Let's say I have a function that changes the Align Self css property via JS.
HTML
<img id= "arrow" src="/images/leftarrow.svg">
CSS
.container {
background-color: $white;
box-shadow: 2px 0px 4px 1px black;
width: 400px;
height: 100vh;
display: flex;
flex-direction: column;
visibility: visible;
position: relative;
z-index: 2;
}
#arrow {
height: 25px;
width: 25px;
position: absolute;
align-self: flex-end;
top: 50vh;
cursor: pointer;
background-color: $white;
border-radius: 50%;
}
JS
function reverseIcon () {
arrow.style.alignSelf = "flex-start";
}
arrow.addEventListener("click", reverseIcon);
Javascript doesn't seem to change the align self property straight away. When I click, it does not change. I jumped into devTools to see what was wrong and it was applied when there was a change in the screen(?). I have no media queries. I tried this on 3 different browsers but AlignSelf doesn't seem to show up on the screen right away. It only actually changes as soon as I jump into devtools or like change the size of the screen. Anyone know why?
**Nevermind, Seems like only Chrome isn't responding to it. Still don't understand what part of this code isn't compatible with Chrome then
Are you sure the alignSelf property gets applied when you change your screen size?
Or is it just the default bahavior? In Dev-Tools, if you inspect, do you see the style-attribute at your image element? If yes, than it could be that your #arrow selector overrides it. If that's the case, I would try to toggle between a class where you can use the !important rule to override the property. Like so:
.flex-start{
align-self: flex-start !important;
}

I need help keeping my CSS tooltip on screen for my website. It unfortunately is too big for the website near the edge of the screen and also is WAY too big for any mobile device and doesn't position correctly (probably because I plan to add very large descriptions in each tooltip). I would like to just use CSS but would be willing to use JS as I'm starting to think that may be the only way to do it correctly, but I'm having a lot of trouble figuring out how to make it work.
I basically had copied over the code from another website with many tweaks if it helps you understand my code better: https://www.w3schools.com/css/css_tooltip.asp
The only results I could find online were about centering the tooltip on the screen which strangely didn't work and code using SCSS which I'm not experienced with and would prefer not to use.
Here is my partial HTML and CSS code:
body {
overflow-x: hidden;
overflow-y: scroll;
}
.ref {
position: relative;
display: inline-block;
border-bottom: 1px dotted black;
}
.ref .versekjv {
visibility: hidden;
width: 250px;
background-color: black;
color: #fff;
text-align: left;
padding: 5px;
border-radius: 6px;
z-index: 98;
position: absolute;
top: 100%;
left: 50%;
margin-left: -125px;
flex-direction: column;
}
.ref .versekjv::after {
content: " ";
position: absolute;
bottom: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: transparent transparent black transparent;
}
.ref:hover .versekjv {
visibility: visible;
}
.redletters {
color:red;
}
#media screen and (max-width:1000px){
.ref .versekjv {
font-size: 1rem;
max-width: 20rem;
position: fixed;
bottom: auto; top: 13%;
left: 78%;
text-align: left;
transform: translate(-50%);
transform: translateX(-50%);
white-space: normal;
z-index: 98;
}
.ref .versekjv::after {
border-color: transparent;
}
}
<li class="box"><a>
<div class="innerbox">Reference</div>
<div class="innerbox"><u class="ref">Reference<span class="versekjv"><b>Bible Book</b><p><i>#</i> Verse Text</p></span></u></div>
<div class="innerbox"><u class="ref">Reference<span class="versekjv"><b>Bible Book</b><p><i>#</i> Verse Text</p></span></u>; <u class="ref">Reference<span class="versekjv"><b>Bible Book</b><p><i>Verse Num.</i> Verse Text</p></span></u></div>
</a></li>
Thank you so much for your help!
First, you need to get the DOM object of your tooltip,
let tooltip = document.querySelector(".ref .versekjv")
Then, you can use the js method "getBoundingClientRect", which gives you an object that has top, right, left and bottom fields which give you the distances of your element from top, right, left and bottom of the viewport. If your element is fully visible inside the element, all four fields would be positive numbers, otherwise it means it's partly invisible, for example a left field of "-10" means about 10px of length of your elements is beyond the left edge of the viewport.
What you can do is that you always check the top, left, ... distances of your element, and if they are negative numbers, manually change them and thus position your element correctly, which could be achieved like this:
tooltip.style.left = 20
Objective:
I would like the Header, Tab Section, and the Radio Button Section to be fixed in a form (see image below). Meaning that they should always be in view, and never have any overlapping elements.
The form looks like the following:
This is working fine when I simply scroll down on the form:
The Problem:
When I open the Angular Material dropdown, it overlaps over the Radio Button Section:
Here is the HTML. The highlighted sections are the elements that I want to be fixated on the form:
And here is the CSS for the 3 sections
//Header:
.module__header {
position: fixed;
top: 0px;
z-index: 1001;
display: flex;
height: 35px;
width: 100%;
background-color: #082749;
color: #FFFFFF;
font-size: 14px;
font-weight: 500;
align-items: center;
justify-content: stretch;
padding: 0;
margin-bottom: 0;
}
// Tab Section:
.mat-tab-label-container {
position: fixed;
top: 35px;
padding-top: 10px;
z-index: 1001;
width: 100%;
background: #fff;
}
// Radio Button Section:
.timaticFullTextView {
padding-top: 35px;
padding-left: 15px;
padding-bottom: 15px;
background: #fff;
z-index: 1001;
position: fixed;
width: 100%;
border-bottom: 1.5px solid gray;
}
I have tried changing the cdk-overlay-container to a z-index of <1001, but that still is overlapping the Radio Button Section.
How can I have the opened dropdown display underneath all 3 sections?
Edit: Adding screenshot to show the cdk-overlay that is giving issues. I have tried removing and lowering the z-index, but it doesn't have any effect
The problem is that mat-tab-body has z-index: 1 and this won't allow your fixed view inside to have a higher elevation. You can remove the z-index from mat-tab-body put then your content without a z-index won't be clickable anymore so you have to add a z-index and position to your not fixed content.
The code would have to look something like this:
<mat-tab>
<mat-tab-body> <!-- <-- added automatically -->
<div class="tab-header"></div>
<div class="tab-content"></div>
</mat-tab-body>
</mat-tab>
::ng-deep mat-tab-body {
z-index: unset !important;
}
.tab-header {
position: fixed;
z-index: 1001;
}
.tab-content {
position: relative;
z-index: 1;
}
You've found the right element whilst applying styles to the wrong one.
Here is how I made it work
.cdk-global-overlay-wrapper, .cdk-overlay-container {
z-index: 99999 !important;
}
I would like to get a circle to expand from itself, while keeping the original circle. What I want is something like when you hover over the circles (e.g. water) on this page (click lets get started to see the circles). I'm not sure how to do this. Note that my knowledge of jQuery is quite small, so if you find a way to do this with jQuery, can you try to keep it simple? Thanks in advance. The earlier the better, as this is for a school project.
I tried to make the div have a function for onmouseover, but then I don't know how to get the rest. I was thinking about while the div animates from a smaller width and height, to move the circle, but the circle will still expand from the middle, and not the old circle.
Start with a CSS-only setup, then see if you actually need Javascript at all. This will generally always be more responsive/faster-loading. However, if you're already loading a JS library and it has functions built for this (like jQuery), then sure make use of them. There are plenty of tutorials for animating elements, CSS or JS.
Play around with numbers and styling as you wish.
Codepen
#container {
width: 100%;
height: 100vh;
display: flex;
justify-content: center;
align-items: center;
}
.circle {
width: 200px;
height: 200px;
background-color: red;
border-radius: 50%;
}
.circle:before {
content: "";
width: 200px;
height: 200px;
border-radius: 50%;
position: absolute;
z-index: -1;
display: inline-block;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
transition: 0.5s ease-in-out;
}
.circle:hover:before {
transform: scale(1.7) translate(-20%,-30%);
background-color: pink;
}
<div id="container">
<div class="circle red"> </div>
</div>
I am trying to do a very simple quiz like this one:
https://www.sitepoint.com/simple-javascript-quiz/
I tried to make it more responsive and added this line:
<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0"/>
It worked fine but when I add a long text on the alternatives of each question, the button "Next Question" stay behind the text, only on mobile (iphone 6, safari).
I tried to add a z-index: 1000; and nothing changed:
button{
font-family: 'Work Sans', sans-serif;
font-size: 22px;
background-color: #279;
color: #fff;
border: 0px;
border-radius: 3px;
padding: 20px;
cursor: pointer;
margin-bottom: 20px;
z-index:1000;
}
So, there's a few things wrong here. As said above you need to remove the height from .quiz-container and remove the absolute positioning from .slide.
What I would suggest is that you add display: none; to slide then your active style to display:block - this will correctly display the button where it should be. With that said, you will lose the fade effect. You'd need to add this CSS to get it back. Hope this helps!
.quiz-container {
position: relative;
margin-top: 40px;
}
.slide {
width: 100%;
opacity: 0;
display: none;
}
.active-slide {
opacity: 1;
display: block;
}
You set position: absolute to your quizz questions, so they will ignore the space of every element you set in HTML.
A large z-index will only put an element above another, that's the why you see the quizz questions above the button.
The problem will be solved if you increment the height of quiz-container on mobile screen (try use #media screen).
https://www.w3schools.com/cssref/css3_pr_mediaquery.asp
I recomend you to find another way to put your questions at the top of page instead using position: absolute
The problem really is that your quiz-container div has a fixed height of 200px, and you can't make it fluid because your slides have position:absolute, which removes them from the flow and prevents the parent growing in height accordingly.
So you need to re-think how to go about this.
An interesting approach would be to use flexbox, controlling which slide to show with the order property.
.quiz-container {
margin-top: 40px;
overflow: hidden;
}
#quiz{
display: flex;
}
.slide {
opacity: 0;
transition: opacity 0.5s;
/*gives each slide 100% width and prevents it from growing or shrinking*/
flex: 0 0 100%;
}
.active-slide {
opacity: 1;
/*sets the order to -1, so it's positioned before all other flex-items*/
order: -1;
}
Hi there, I've downloaded LeanModal, but whenever I show the modal, it seems the overlay is applying to even the modal itself.
I assumed it was a z-index fix, but it seems that (when looking in chrome dev tools) that the z-index is being applied after the fact by leanmodal, and the CSS is ignored.
#lean_overlay {
position: fixed;
z-index: 100;
top: 0px;
left: 0px;
height:100%;
width: 100%;
background: #000;
display: none;
}
// can't get it to sit above the overlay
#popup {
z-index: 150; // it looks like it's being overwritten in dev tools
width: 600px;
padding: 30px;
display: none;
background: #FFF;
}
$("#i").leanModal();
Anyone else run into this?
Thanks
