JS Sapper + Bulma breakpoints in (S)CSS - javascript

I'm trying to use Sapper with Bulma and (S)CSS.
My goal is to apply various paddings on "main" inside of src/routes/layout.html, with padding on desktop devicees, and without (or a smaller one) on mobile.
Using the predefined breakpoints or mixins doesn't work properly for me, as the following code raises an SCSS error :
EDIT: this is the svelte component:
<script>
import 'bulma/css/bulma.css'
// or import 'bulma/bulma.sass' ???
</script>
<style type="text/scss">
main {
position: relative;
max-width: 56em;
background-color: white;
margin: 0 auto;
sizing: border-box;
padding: 0.5em;
+desktop-only {
padding: 2em;
}
}
</style>
What's wrong and how to fix it ?

I'm trying to use interact.js in rails 6, but I cannot get it to work. I am a newbie so this may be a common question, but how do I properly import an external library like interact.js. I've tried everything I've found online so I imagine I'm looking for the wrong thing. Any help will be appreciated, Thanks in advance!
this syntax:
import '#interactjs/auto-start'
import '#interactjs/actions/drag'
import '#interactjs/actions/resize'
import '#interactjs/modifiers'
import '#interactjs/dev-tools'
import interact from '#interactjs/interact'
is used for npm modules import. You can't do that in the browser without preprocessing your code. You can import the library like this, preferably in a separate script tag. But if you plan to import only one library you can set it
<script src="CDN url"></script>
Put it above your other script tag. Find an appropriate CDN host for your library. Example: https://cdnjs.com/libraries/interact.js/1.0.2
You can't use those import statements like this. If you import the library from CDN, you can use it like in the documentation. Look at https://interactjs.io/docs/installation CDN pre-bundled usage. I presume interact is globally exposed and you don't have to import anything.
If you want to go the proper way about this, you would be setting up a separate project/folder for your frontend application. That application has to be then built, and you attach the built distribution files in your Rails HTML. It depends on your purposes.

Unable to overwrite react-h5-audio-player scss variables

I've just included react-h5-audio-player into my project and following the README page to customise the styles by overwriting the SCSS variables responsible for the colours.
However it seems like my styles just get ignored. Do you have any idea what could be going wrong here? Thank you very much.
This is the codesandbox where I've reproduced the problem: https://codesandbox.io/s/react-and-scss-forked-yeu0q?file=/src/index.js
As you can see I've included the style.css (which contains the overwritten variables) in 3 places -- before importing audioplayer's js, before importing audioplayer's css and after both of these just in case to see if any of these works. I also randomly added !default and !important to the variables hoping that at least some of the syntax would work, but the styles are just keep being ignored.
I will also include the code to this post if someone prefers seeing it here rather in codesandbox:
style.css:
html,
body {
background-color: papayawhip;
font-family: sans-serif;
h1 {
color: tomato;
}
}
$rhap_theme-color: #ff0000; // Color of all buttons and volume/progress indicators
$rhap_background-color: #ff0000 !important; // Color of the player background
$rhap_bar-color: #ff0000 !default; // Color of volume and progress bar
$rhap_time-color: #0000ff !important !default; // Font color of current time and duration
$rhap_font-family: inherit !important; // Font family of current time and duration
index.js:
import React from "react";
import { render } from "react-dom";
import "./styles.scss";
import AudioPlayer from "react-h5-audio-player";
import "./styles.scss";
import "react-h5-audio-player/src/styles.scss";
import "./styles.scss";
const App = () => (
<div>
<h1>Hello</h1>
<AudioPlayer src="http://example.com/audio.mp3" />
</div>
);
render(<App />, document.getElementById("app"));
For another approach you can use this example:
.rhap_container {
background: #f7f7f9;
}
.rhap_controls-section {
margin-bottom: 15px;
}
.rhap_progress-section {
height: 20px;
padding-bottom: 20px;
}
.rhap_main-controls-button {
width: 80px !important;
height: 80px !important;
}
.rhap_main-controls-button {
width: 56px;
height: 56px;
display: block;
}
.rhap_main-controls-button svg {
color: #ff5555;
width: 100%;
height: 100%;
}
.rhap_progress-filled,
.rhap_progress-indicator {
background-color: #ff5555 !important;
}
.rhap_button-clear.rhap_volume-button {
color: #ff5555 !important;
}
.rhap_volume-bar, .rhap_volume-indicator {
background-color: red;
}

SASS styles injected by innerHTML don't work

I want to inject style to div in component. My issue is it's scss and in application we use scss but style does not want to work. When inject the same style as css one. Everything works fine. The question is how can I force my component to execute style like this? Is it even possible or should I convert scss style to css one?
HTML.TS
<div id="myExampleId">
<div #htmlContainer [innerHtml]="htmlToDisplay | safehtml"></div>
</div>
Style to display in component:
<style>
#myExampleId {
table {
border-collapse: collapse;
width: 100%;
}
th{
background-color:#fe996b;
}
td, th {
border: 1px solid #999;
padding: 0.5rem;
text-align: left;
}
body {
background-color: #fe996b;
}
}
</style>
Import the styles not in the template but in the component itself.
Look in Angular docs https://angular.io/guide/component-styles

How to make a custom Web Component "height:100%" of the page?

I wrote a Web Component using Vue.js and vue-custom-element. Now I want to make my-chat and my-whiteboard Web Components "height:100%".I'm using the component like this:
// App.vue
<template>
<splitpanes class="default-theme">
<pane>
<my-chat></my-chat>
</pane>
<pane>
<my-whiteboard></my-whiteboard>
</pane>
</splitpanes>
</template>
The only way that I know is to set the height of all parents to 100% like this:
html,
body,
splitpanes,
pane,
my-chat,
my-whiteboard {
height: 100%;
}
//main.js
...
// Load custom element plugin
Vue.use(vueCustomElement);
// Define web components
Vue.customElement("skyroom-whiteboard", Whiteboard);
Vue.customElement("skyroom-chat", Chat);
...
And do this for the all tags inside web my-chat and my-whiteboard too!!!
The problems:
This is not working for my- components.
It seems to be wrong! Isn't there any right way to do this?
The simple way to do it is to use
my-chat, my-whiteboard {
min-height: 100vh;
}
However, when one of them becomes taller than 100vh, it will grow without the other one. So, most likely, ...
display: block;
height: 100vh;
overflow-y: auto;
... will do a better job.
Here's an example (you don't need any the CSS after /* let's test it */ line but I had to add it as all of them are custom elements and, by default, they have a display value of inline):
my-chat,
my-whiteboard {
display: block;
height: 100vh;
overflow-y: auto;
}
/* let's check it */
my-chat,
my-whiteboard {
box-sizing: border-box;
}
tester {
height: 200vh;
padding: 1rem;
}
splitpanes { display: flex; }
pane:first-child { flex-basis: 75%; }
pane:last-child { flex-grow: 1; }
body { margin: 0; }
/* don't use this line in your app, it will likely break stuff
* I used it here because I don't have any content to break! */
.default-theme * { display: block; }
<splitpanes class="default-theme">
<pane>
<my-chat>
<tester>my-chat</tester>
</my-chat>
</pane>
<pane>
<my-whiteboard>
<tester>my-whiteboard</tester>
</my-whiteboard>
</pane>
</splitpanes>
Important note: If any of your components gets parsed by Vue into actual <div> elements, you'll need to change the selectors accordingly (but you did say they're custom elements, so I'm guessing they're used as-is).

How to change div elements' css inside iframe [duplicate]

I have not had much success finding how to style Google's new recaptcha (v2). The eventual goal is to make it responsive, but I am having difficulty applying styling for even simple things like width.
Their API documentation does not appear to give any specifics on how to control styling at all other than the theme parameter, and simple CSS & JavaScript solutions haven't worked for me.
Basically, I need to be able to apply CSS to Google's new version of reCaptcha. Using JavaScript with it is acceptable.
Overview:
Sorry to be the answerer of bad news, but after research and debugging, it's pretty clear that there is no way to customize the styling of the new reCAPTCHA controls. The controls are wrapped in an iframe, which prevents the use of CSS to style them, and Same-Origin Policy prevents JavaScript from accessing the contents, ruling out even a hacky solution.
Why No Customize API?:
Unlike reCAPTCHA API Version 1.0, there are no customize options in API Version 2.0. If we consider how this new API works, it's no surprise why.
Excerpt from Are you a robot? Introducing “No CAPTCHA reCAPTCHA”:
While the new reCAPTCHA API may sound simple, there is a high degree of sophistication behind that modest checkbox. CAPTCHAs have long relied on the inability of robots to solve distorted text. However, our research recently showed that today’s Artificial Intelligence technology can solve even the most difficult variant of distorted text at 99.8% accuracy. Thus distorted text, on its own, is no longer a dependable test.
To counter this, last year we developed an Advanced Risk Analysis backend for reCAPTCHA that actively considers a user’s entire engagement with the CAPTCHA—before, during, and after—to determine whether that user is a human. This enables us to rely less on typing distorted text and, in turn, offer a better experience for users. We talked about this in our Valentine’s Day post earlier this year.
If you were able to directly manipulate the styling of the control elements, you could easily interfere with the user-profiling logic that makes the new reCAPTCHA possible.
What About a Custom Theme?:
Now the new API does offer a theme option, by which you can choose a preset theme such as light and dark. However there is not presently a way to create a custom theme. If we inspect the iframe, we will find the theme name is passed in the query string of the src attribute. This URL looks something like the following.
https://www.google.com/recaptcha/api2/anchor?...&theme=dark&...
This parameter determines what CSS class name is used on the wrapper element in the iframe and determines the preset theme to use.
Digging through the minified source, I found that there are actually 4 valid theme values, which is more than the 2 listed in the documentation, but default and standard are the same as light.
We can see the code that selects the class name from this object here.
There is no code for a custom theme, and if any other theme value is specified, it will use the standard theme.
In Conclusion:
At present, there is no way to fully style the new reCAPTCHA elements, only the wrapper elements around the iframe can be stylized. This was almost-certainly done intentionally, to prevent users from breaking the user profiling logic that makes the new captcha-free checkbox possible. It is possible that Google could implement a limited custom theme API, perhaps allowing you to choose custom colors for existing elements, but I would not expect Google to implement full CSS styling.
As guys mentioned above, there is no way ATM. but still if anyone interested, then by adding in just two lines you can at least make it look reasonable, if it break on any screen. you can assign different value in #media query.
<div id="recaptchaContainer" style="transform:scale(0.8);transform-origin:0 0"></div>
Hope this helps anyone :-).
I use below trick to make it responsive and remove borders. this tricks maybe hide recaptcha message/error.
This style is for rtl lang but you can change it easy.
.g-recaptcha {
position: relative;
width: 100%;
background: #f9f9f9;
overflow: hidden;
}
.g-recaptcha > * {
float: right;
right: 0;
margin: -2px -2px -10px;/*remove borders*/
}
.g-recaptcha::after{
display: block;
content: "";
position: absolute;
left:0;
right:150px;
top: 0;
bottom:0;
background-color: #f9f9f9;
clear: both;
}
<div class="g-recaptcha" data-sitekey="Your Api Key"></div>
<script src='https://www.google.com/recaptcha/api.js?hl=fa'></script>
Unfortunately we cant style reCaptcha v2, but it is possible to make it look better, here is the code:
Click here to preview
.g-recaptcha-outer{
text-align: center;
border-radius: 2px;
background: #f9f9f9;
border-style: solid;
border-color: #37474f;
border-width: 1px;
border-bottom-width: 2px;
}
.g-recaptcha-inner{
width: 154px;
height: 82px;
overflow: hidden;
margin: 0 auto;
}
.g-recaptcha{
position:relative;
left: -2px;
top: -1px;
}
<div class="g-recaptcha-outer">
<div class="g-recaptcha-inner">
<div class="g-recaptcha" data-size="compact" data-sitekey="YOUR KEY"></div>
</div>
</div>
Add a data-size property to the google recaptcha element and make it equal to "compact" in case of mobile.
Refer: google recaptcha docs
What you can do is to hide the ReCaptcha Control behind a div. Then make your styling on this div. And set the css "pointer-events: none" on it, so you can click through the div (Click through a DIV to underlying elements).
The checkbox should be in a place where the user is clicking.
You can recreate recaptcha , wrap it in a container and only let the checkbox visible. My main problem was that I couldn't take the full width so now it expands to the container width. The only problem is the expiration you can see a flick but as soon it happens I reset it.
See this demo http://codepen.io/alejandrolechuga/pen/YpmOJX

grecaptcha.render('myrecaptcha', {
'sitekey': '6Lc7JBAUAAAAANrF3CJaIjt7T9IEFSmd85Qpc4gj',

Great!
Now here is styling available for reCaptcha..
I just use inline styling like:
<div class="g-recaptcha" data-sitekey="XXXXXXXXXXXXXXX" style="transform: scale(1.08); margin-left: 14px;"></div>
whatever you wanna to do small customize in inline styling...
Hope it will help you!!
I came across this answer trying to style the ReCaptcha v2 for a site that has a light and a dark mode. Played around some more and discovered that besides transform, filter is also applied to iframe elements so ended up using the default/light ReCaptcha and doing this when the user is in dark mode:
.g-recaptcha {
filter: invert(1) hue-rotate(180deg);
}
The hue-rotate(180deg) makes it so that the logo is still blue and the check-mark is still green when the user clicks it, while keeping white invert()'ed to black and vice versa.
Didn't see this in any answer or comment so decided to share even if this is an old thread.
Just adding a hack-ish solution to make it responsive.
Wrap the recaptcha in an extra div:
<div class="recaptcha-wrap">
<div id="g-recaptcha"></div>
</div>
Add styles. This assumes the dark theme.
// Recaptcha
.recaptcha-wrap {
position: relative;
height: 76px;
padding:1px 0 0 1px;
background:#222;
> div {
position: absolute;
bottom: 2px;
right:2px;
font-size:10px;
color:#ccc;
}
}
// Hides top border
.recaptcha-wrap:after {
content:'';
display: block;
background-color: #222;
height: 2px;
width: 100%;
top: -1px;
left: 0px;
position: absolute;
}
// Hides left border
.recaptcha-wrap:before {
content:'';
display: block;
background-color: #222;
height: 100%;
width: 2px;
top: 0;
left: -1px;
position: absolute;
z-index: 1;
}
// Makes it responsive & hides cut-off elements
#g-recaptcha {
overflow: hidden;
height: 76px;
border-right: 60px solid #222222;
border-top: 1px solid #222222;
border-bottom: 1px solid #222;
position: relative;
box-sizing: border-box;
max-width: 294px;
}
This yields the following:
It will now resize horizontally, and doesn't have a border. The recaptcha logo would get cut off on the right, so I am hiding it with a border-right. It's also hiding the privacy and terms links, so you may want to add those back in.
I attempted to set a height on the wrapper element, and then vertically center the recaptcha to reduce the height. Unfortunately, any combo of overflow:hidden and a smaller height seems to kill the iframe.
in the V2.0 it's not possible. The iframe blocks all styling out of this. It's difficult to add a custom theme instead of the dark or light one.
Late to the party, but maybe my solution will help somebody.
I haven't found any solution that works on a responsive website when the viewport changes or the layout is fluid.
So I've created a jQuery script for django-cms that is dynamically adapting to a changing viewport.
I'm going to update this response as soon as I have the need for a modern variant of it that is more modular and has no jQuery dependency.

With the integration of the invisible reCAPTCHA you can do the following:
To enable the Invisible reCAPTCHA, rather than put the parameters in a div, you can add them directly to an html button.
a. data-callback=””. This works just like the checkbox captcha, but is required for invisible.
b. data-badge: This allows you to reposition the reCAPTCHA badge (i.e. logo and
‘protected by reCAPTCHA’ text) . Valid options as ‘bottomright’ (the default),
‘bottomleft’ or ‘inline’ which will put the badge directly above the button. If you
make the badge inline, you can control the CSS of the badge directly.
In case someone struggling with the recaptcha of contact form 7 (wordpress) here is a solution working for me
.wpcf7-recaptcha{
clear: both;
float: left;
}
.wpcf7-recaptcha{
margin-right: 6px;
width: 206px;
height: 65px;
overflow: hidden;
border-right: 1px solid #D3D3D3;
}
.wpcf7-recaptcha iframe{
padding-bottom: 15px;
border-bottom: 1px solid #D3D3D3;
background: #F9F9F9;
border-left: 1px solid #d3d3d3;
}
if you use scss, that worked for me:
.recaptcha > div{
transform: scale(0.84);
transform-origin: 0;
}
If someone is still interested, there is a simple javascript library (no jQuery dependency), named custom recaptcha. It lets you customize the button with css and implement some js events (ready/checked). The idea is to make the default recaptcha "invisible" and put a button over it. Just change the id of the recaptcha and that's it.

I am just adding this kind of solution / quick fix so it won't get lost in case of a broken link.
Link to this solution "Want to add link How to resize the Google noCAPTCHA reCAPTCHA | The Geek Goddess" was provided by Vikram Singh Saini and simply outlines that you could use inline CSS to enforce framing of the iframe.
// Scale the frame using inline CSS
<div class="g-recaptcha" data-theme="light"
data-sitekey="XXXXXXXXXXXXX"
style="transform:scale(0.77);
-webkit-transform:scale(0.77);
transform-origin:0 0;
-webkit-transform-origin:0 0;
">
</div>
// Scale the images using a stylesheet
<style>
#rc-imageselect, .g-recaptcha {
transform:scale(0.77);
-webkit-transform:scale(0.77);
transform-origin:0 0;
-webkit-transform-origin:0 0;
}
</style>
You can use some CSS for Google reCAPTCHA v2 styling on your website:
– Change background, color of Google reCAPTCHA v2 widget:
.rc-anchor-light {
background: #fff!important;
color: #fff!important; }
or
.rc-anchor-normal{
background: #000 !important;
color: #000 !important; }
– Resize the Google reCAPTCHA v2 widget by using this snippet:
.rc-anchor-light {
transform:scale(0.9);
-webkit-transform:scale(0.9); }
– Responsive your Google reCAPTCHA v2:
#media only screen and (min-width: 768px) {
.rc-anchor-light {
transform:scale(0.85);
-webkit-transform:scale(0.85); }
}
All elements, property of CSS above that’s just for your reference. You can change them by yourself (only using CSS class selector).
Refer on OIW Blog - How To Edit CSS of Google reCAPTCHA (Re-style, Change Position, Resize reCAPTCHA Badge)
You can also find out Google reCAPTCHA v3's styling there.
A bit late but I tried this and it worked to make the Recaptcha responsive on screens smaller than 460px width. You can't use css selector to select elements inside the iframe. So, better use the outermost parent element which is the class g-recaptcha to basically zoom-out i.e transform the size of the entire container. Here's my code which worked:
#media(max-width:459.99px) {
.modal .g-recaptcha {
transform:scale(0.75);
-webkit-transform:scale(0.75); }
}
}
Incase someone wants to resize recaptcha for small devices.
I was using recaptcha V2 with primeng p-captcha (for angular). The issue was that for smaller screens it would go out of the screen.
Although you can't actually resize it (the external thing and all everyone has explained it above) but there is a way with transform property (scaling the the container)
this was my code below the way, I achieved it
p-captcha div div {
transform:scale(0.9) !important;
-webkit-transform:scale(0.9) !important;
transform-origin:0 0 !important;
-webkit-transform-origin:0 0 !important;
}
Other than p-captcha you can use this code snippet below
.g-recaptcha {
transform:scale(0.9);
transform-origin:0 0;
}

Topic is old, but I also wanted to scale the reCAPTCHA widget -- but to make it bigger for phone users, unlike many others who wanted it smaller. The only way that worked was transform: scale(x), but that seemed to make the widget too wide for my page, thus shrinking the rest of the form on the page. Using a container div as shown below fixed my problem, and hopefully it will help someone else who thinks a bigger version is better on a small screen.
<style>
:root {
/* factor to scale the Google widget in potrait mode (on a phone) */
--recaptcha-scale: 2;
}
#media screen and (orientation: portrait) {
/* needed to rein in the width of inner div when it is scaled */
#g_recaptcha_div_container {
width: calc(100vmin / var(--recaptcha-scale));
}
#g_recaptcha_div {
transform: scale(var(--recaptcha-scale));
transform-origin: 0 0;
}
#submit_button {
width: 65vmin;
height: 9vmin;
font-size: 7vmin;
/* needed to scoot the button out from under the scaled div */
margin-top: 10vmin;
}
}
</style>
<html>
<!-- top of form with a bunch of fields to create an acct -->
<div id="g_recaptcha_div_container">
<div id="g_recaptcha_div" class="g-recaptcha" data-sitekey="foo">
</div>
</div>
<input id="submit_button" type="submit" value="Create Account">
<!-- bottom of form -->
</html>
You can try to color it with this css filter hack:
.colorize-pink {
filter: brightness(0.5) sepia(1) hue-rotate(-70deg) saturate(5);
}
.colorize-navy {
filter: brightness(0.2) sepia(1) hue-rotate(180deg) saturate(5);
}
and for the size, use transform css hack
.captcha-size {
transform:scale(0.8);transform-origin:0 0
}
Lets play a little with JavaScript:
First at all, we know that recaptcha badget include all the shit from the most crazy people on Google, so you can only make changes with theme "dark" and "light" on your web.
Take a look to my website
SantiagoSoñora.
let recaptcha = document.querySelector('.g-recaptcha');
With this, you only can touch simple settings of the badge, like z-index and size, but no much more...
So far, i made two functions that set data-theme to light or dark mode at innit. Note that its neccessary assign the "light" because Google not include that by default.
function reCaptchaDark() {
document.addEventListener('DOMContentLoaded', (event) => {
recaptcha.setAttribute("data-theme", "dark");
})
}
function reCaptchaLight() {
document.addEventListener('DOMContentLoaded', (event) => {
recaptcha.setAttribute("data-theme", "light");
})
}
Then, for example, my web looks if user prefers a dark or a light theme, and set that configurations to the recaptcha bag:
(theme.onLoad = function() {
if (window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches) {
reCaptchaDark();
toggleTheme();
}
else {
reCaptchaLight();
}
})();
Note that my code for toggle from dark to light is on the toggleTheme() function.
Keep doing magic: You should configure a class on the html tag or something else on your web for made the change between dark and light theme, and with that we now modify the src on the iframe so when we toggle dark/light mode ,with our button it changes:
theme.onclick = function() {
toggleTheme();
if (html.classList.contains('dark')) {
recaptcha.setAttribute("data-theme", "dark");
setTimeout(function() {
let iframes = document.querySelectorAll('iframe');
iframes[0].src = iframes[0].src.replace('&theme=light', '&theme=dark');
}, 0);
}
else {
recaptcha.setAttribute("data-theme", "light");
setTimeout(function() {
let iframes = document.querySelectorAll('iframe');
iframes[0].src = iframes[0].src.replace('&theme=dark', '&theme=light');
}, 0);
}
}
And here you go, the recaptcha badge change from dark to light "preassigned" themes by Google bad guys.
And last but not least, a function that updates the page to change if your theme is dark by default.
This update the LocalStorage
(function() {
if( window.localStorage ) {
if( !localStorage.getItem('firstLoad') ) {
localStorage['firstLoad'] = true;
window.location.reload();
}
else
localStorage.removeItem('firstLoad');
}
})();
You can use the class .grecaptcha-badge for some css changes, like opacity and box-shadow, -> (use !important)
Thats all, hope you can implement on your site
