Sliding bottom panel through HTML, CSS, JS by clicking on card/tile - javascript

I'm beginner and trying to display details of a card/tile from the sliding bottom of the page over click action. I already found one of the template with my requirements and trying to customize. I found few code samples on how can I do sliding effect from the bottom. I was able to findout solution but it works with hover action where as I am trying to do is as below.
Scenario:
As shown in the mockup screenshot >> Cards will be displayed in the home screen >> users clicks on one of the Card >> background should be transparent 50% and movie details should get displayed in sliding button panel >> PLAY NOW should be active
Like the left menu loading in the given template below - playdo template
one of the similar example I found is this but as I mentioned this is hover feature - Sliding bottom panel through HTML, CSS and JS
An other from the top sliding - http://hoveralls.design-way.ro/
Template in the screenshot that i am using is - https://github.com/tomclaus/playdo

Hi and welcome to the front-end world.
What you need to do is to create two different css classes that contain the things you want to change (in this case the top and the transparency). One for when your card/tile is "minimized" and one for when is "maximized".
.minimized{
background-color: rgba(255,255,255, 0.5);
top: 90%;
}
.maximized{
background-color: rgba(255,255,255, 1);
top: 75%;
}
and then apply a click event to your card/title using jQuery or Javascript and swap those classes to give the proper behavior.
$("#card").click(function(){
if($(this).hasClass('minimized')){
$(this).removeClass('minimized');
$(this).addClass('maximized');
}
else{
$(this).removeClass('maximized');
$(this).addClass('minimized');
}
});
Make sure that the CSS for your card/tile includes this:
-webkit-transition: all ease 1s;
That line will give a smooth transition when you swap the minimized and maximized classes.
Please check this jsfiddle to see the code in action.
ps. Since I'm using the "-webkit-" prefix for the transition this example only will work with webkit browsers (safari and chrome)

Ok I finally understood what you want to do with the mockup.
Well the idea is the same, and I'm sure it can be implemented in many other ways but I hope this one helps you to understand what is going on.
Pretty much you need two states (classes) for the actions you want to achieve.
A Minimized and Maximized for the div that holds the movie details.
#details{
z-index: 4;
position: absolute;
-webkit-transition: all ease 1s;
background-color: #2980b9;
color: white;
padding: 30px;
width: 100%;
height: 300px;
}
.minimized{
top: 100%;
}
.maximized{
top: 40%;
}
And other two for the "gray courtain" that sits on top of the cards when the details are show.
#courtain{
position:absolute;
background-color: rgba(100,100,100, 0.5);
width: 100%;
height: 100%;
}
.active{
z-index: 2;
}
.deactive{
z-index: -1;
}
All these must be controlled or toggled using Javascript with a click event for the Card.
function hideAndShow(){
var details = $('#details');
var courtain = $('#courtain');
if(details.hasClass('minimized')){
courtain.removeClass('deactive');
courtain.addClass('active');
details.removeClass('minimized');
details.addClass('maximized');
}
else{
courtain.removeClass('active');
courtain.addClass('deactive');
details.removeClass('maximized');
details.addClass('minimized');
}
}
It is important to check the "z-index" values on the states to place them correctly above the other, the one with the highest z-index value is the one that remains on top.
I've updated the JSFiddle, check it out and hopefully all this makes sence.

scaleY property not maintained properly for small screens

I am tryng to fix a css bug for mobile screens
when I click section 1 content opens and if i move till the bottom of the section one content and after that if I click section 1 content closes.
but I dont see section 2 after that I see section 3 since the screen moves upwards.
how to retain the section 2 in our screen.
am I doing anything wrong with the scaleY property.
providing the related code below
I used scrollIntoView but still not point to second one any idea???
I used window.scrollTo(0, 0) but still not point to second one any idea???
.television .chromecast .sun .sunItem > .bulb {
overflow: hidden;
transition: transform .5s, max-height .5s;
transform: scaleY(0);
box-sizing: border-box;
max-height: 0;
transform-origin: center top;
}
.television .chromecast .sun .sunItem.selected > .bulb {
transform: scaleY(1);
max-height: 100%;
}
We need to invoke properly on the select function
onSelect() {
this.props.onSelect(this.props.id);
this.focusDiv();
}
That's the expected behaviour. The scroll position is retained but you remove content from the top of the screen so you end up further down in the page.
It's always a bad idea to collapse the previous elements when expanding a new one, especially on mobile.
To fix that, you will need to script a scrolling to the top of the open section. That could easily be achieved using jQuery.ScrollTo() or something similar, but to be honest, I would just leave the previous sections open, unless the users have a tendency to scroll back up and that would require to much scrolling to get back to the top of the page. Other UX solutions like a scroll to top link might come in handy to solve that.

CSS transition not working when two classes are added

Before I say anything, I looked at about a dozen SO threads including this one which you'll see the code suggested in there in my JSBin as well: Why does this CSS transition event not fire when two classes are added?
The issue is that adding two classes back to back too fast results in no transition animation whatsoever.
I'm implementing this into a legacy JS custom right click menu and making it mobile friendly with just CSS by first applying the mobile styles with .mobile-menu then an animation class of .mobile-menu-show when they long press (since there's no right click mouse button).
The transitions don't work this way though. If I add .mobile-menu on page load it's fine, but I can't because I'm adding the mobile-menu class based on how the right click menu is triggered (long press == mobile styles, right click == normal styles)
Demo code: http://jsbin.com/maxuku/edit?html,css,output
==Edit==
Hopefully to clarify, I want the menu you see at the default to go hidden (translateY(100%)) then slide up from the bottom. If you use Slack, long press on a message. Or iPhone's had this same concept here where it would slide up:
please change css class as below
.context-menu {
position: fixed;
bottom: -100%;
left: 0;
right: 0;
z-index: 100;
-webkit-transition: all 0.25s; /* Safari */
transition: all 0.25s;
}
.mobile-menu {
background: #fff;
width: 100%;
box-sizing: border-box;
box-shadow: 0 0 5px rgba(0,0,0,0.5);
}
.mobile-menu-show {
bottom: 0;
}

On input focus make background look like modal

On my webpage, I have a footer which has a textarea box. When the user clicks in the textarea, I want the rest of the page to darken by 60%, kindof like they are in a modal. I am a noob when it comes to advanced css so I am unsure of the properties to apply.
I am using bootstrap 3, javascript and knockout. I know how to detect when the user is in the text area I just want to change the background so everything else is opaque.
A jsFiddle would be wonderful as well :)
We use a combination of CSS and JQuery JavaScript for that. You'd basically use some Overlay method first to overlay the whole page (e.g. See Technique #1 from the Link).
With the help of JavaScript, We attach to events of the forms to:
Show the Overlay
Make the required form elements, e.g. the first Div inside the form, appear above the Overlay ("z-index" CSS attribute)
CSS:
Overlay has Z-Index 10, so give the relevant element the Z-Index 11 to appear on top:
form > div { z-index: 11; }
this JQuery JavaScript can look like this:
$(document).on("focus", "textarea", function() {
$(".overlay").show();
});
Beware, this is not only a "background" topic, if you want to prevent users to do any interaction with the page, you need an overlay which actually blocks clicks. Also, in our case, we also had to prevent any links to be triggered which are below the overlay. Users were still able to go through the links using the TAB key on they keyboard to navigate to a button and click it using the Space key, so we also added JavaScript code to prevent that when in editing mode.
EDIT: a very basic Fiddle
Here is how I would do this - When the user clicks in the text area, set a class on body, and style the class.
with jQuery (you can use vanilla js too)
$('.my-textarea').on('focus', function() {
$('body').addClass('dark');
});
$('.my-textarea').on('blur', function() {
$('body').removeClass('dark');
});
body.dark {
background-color: #333;
opacity: 0.6;
}
A good solution is to make a modal appear behind the input and not just making the background darker, this can be accomplished with css alone
...
<style>
textarea:focus{
z-index: 901;
position: relative;
}
textarea ~ .textarea-modal{
position: fixed;
background-color: transparent;
margin: auto;
left: 0;
right: 0;
top: 0;
bottom: 0;
width: 100%;
height: 100%;
z-index: 900;
pointer-events: none;
transition: background-color .5s ease;
}
textarea:focus ~ .textarea-modal{
pointer-events: auto;
background-color: rgba(0,0,0,0.3);
}
</style>
...
<div>
<textarea></textarea>
<div class="textarea-modal"></div>
</div>
...
feel free to change the selectors to target specific elements, however at the moment when you focus on the textarea a modal would appear below it with other elements behind.

buttons not keeping up with slider when window re-size

Whenever i re-size my window the slider buttons (next/previous) disappear and do not move with the slider. Any idea on how to fix this?
JSFIDDLE:https://jsfiddle.net/b31kvqwr/
Buttons CSS:
#nav img {
position: absolute;
top: -10px;
cursor:pointer;
color:grey;
width:40px;
height:30px;
}
#prev {
margin-left: 530px;
font-size: 10px;
}
#next {
right: -30px;
margin-top: 13px;
}
PS: if the result in the jsfiddle doesn't show, expand the result tab.
This is how the slider looks like when full screen (the right way);
This what happens when i re-size the browser horizontally:
The buttons aren't moving with the slider. Any help please?
The problem at the moment is that you are using margin-left:530px; meaning that the arrows will always be 530px from the left of the screen no matter the size of the screen. It also looks like what ever is wrapping it has a set width and isn't resizing, your code was to messy for me to find this but there are a few thing that I found to make the problem a little better,
https://jsfiddle.net/b31kvqwr/2/
I have managed to keep it the correct place for a lot of the, however to improve get it working perfectly you will need to create 1-2 #mediaqueries to tweet the alignments at different sizes to make it perfect.
The way I did this was by changing margin-left to position:absolute and use a left positioning instead on your prev and next buttons;
#prev {
left: 50%;
font-size: 10px;
position:absolute;
}
#next {
margin-top: 13px;
left:58%;
position:absolute;
}
As I side note I would recommend cleaning up your code like #TingGaint said as it is insanely messy. Also when posting on stack try only include the relevant code not all of it as it makes it quicker and easier to look through and help.
EDIT
I have found the problem, still do what I said above however now instead of have the arrows div where they are now, move them out and so there below <div id="wrapper"> however you will have to play around with the placement as they will be at the top of the screen. However now they stay in the same place when re-sizing!

Highlight a section of an image in JavaScript

I run a small webpage that allows users to click on various links using image maps. I'd like to highlight the section that a user clicks on to give some feedback to the user (they may be clicking on several different parts rapidly).
Is there a way I can invert (or otherwise highlight) a small section of an image JavaScript?
Instead of using image maps, you could try this CSS method:
Use a transparent <div> on top of each "image-map" part (link), and then use the CSS :hover pseudo-class to handle the highlighting.
CSS:
#image {
position: relative;
width: 400px;
height: 100px;
background-image: url(image_map.png);
}
#map-part {
position: absolute;
top: 10px;
left: 10px;
width: 50px;
height: 50px;
background-color: transparent;
}
#map-part:hover {
background-color: yellow; /* Yellow Highlight On Hover */
opacity: 0.2;
filter: alpha(opacity=20);
}
HTML:
<div id="image">
<a id="map-part" href="http://www.example.com/"></a>
</div>
Note that this will only work for rectangular links.
Take a look at jQuery MapHilight.
I'm not sure it does exactly what you need, but you can achieve that with minor tweaking.
How about overlaying a semi-transparent <DIV> block over the clicked area to highlight it?
There are many way,
In a d fashion way, break down your images into many smaller pieces and using table to combine them. After that, by using javascript to replace thr "src" attribute for the highlight effect.
In another CSS way, use CSS to clip the alt. image on top of the original, and control which area should be visible.
It is better to have a single image for all rather then many small images to speed up and user will get it without delay by network.
