How to animate a CSS-loaded SVG background with JavaScript - javascript

I have the following SVG (shortened version).
.line {
width: 100%;
height: 500vh;
margin-top: 100px;
opacity: 0.8;
background:
linear-gradient(to bottom, #fff, transparent) top/100% 1024px no-repeat,
linear-gradient(to top, #fff, transparent) bottom/100% 128px no-repeat,
url(line.svg) top/768px;
}

</svg>
I don't think that works, but it's the gist of the code. Basically, I have added some JavaScript straight to the SVG, to animate the opacity of each separate path in and out. I want it to sort of "sparkle".
But this isn't working if I style an element with this .line class. It successfully draws the SVG in a repeating fashion, but it doesn't do the animation. I'm wondering how to accomplish this. I don't want to use a purely inline SVG which I could directly animate in a similar way, because I want to use this SVG on multiple pages and don't want to load it inline on each page. But if that's the only way to do it that would be good to know.
Do I need something like this?
Basically my HTML document is like this:
<html>
<body>
<section>something</section>
<section class='line'></section>
<section>something else</section>
</body>
</html>
The .line class sets the CSS background-image to the line.svg file.


EDIT3 (FINAL): What I alluded to in EDIT2 below IS possible and here it is, since I don't have your "line.svg" and I wanted to show a working snippet, I just inlined svg binary into my css , this should be interchangeable with a proper svg file (as in: if .line had background: url("line.svg") it will work identically to my example)
Next time PLEASE post the whole question before publishing. That took way too many edits due to the question being changed.

EARLIER (before Question-er updated question)
If I understand your question and code - you want to have that same 'fade-in and out' effect but without the inline javascript. You can seperate js from the html and add that svg path with js.
window.onload=function() {
var line=document.getElementsByClassName("line")[0];
console.log(line);
/* not sure why I had to concatonate the various pieces, prob because of the code snippet editor in SO */
line.innerHTML='<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="200px" height="200px" viewBox="0 0 200 200" enable-background="new 0 0 200 200" xml:space="preserve">'+

'<path class="myPath" fill="#070707" d="M200,199.422c-0.219,0.195-0.438,0.391-0.664,0.58H200V199.422z"/>'+
'</g>'+
'</svg>';
};
.line {
/*transition: opacity 512ms ease-in-out;*/
animation: shine 1s ease-in-out infinite;
}
#keyframes shine {

<section class='line'></section>
<section>something else</section>
</body>
</html>
NOTE: the above is the OLD snippet, please scroll up in same answer for the final answer which is in the first snippet
EDIT2: ...I believe it may be doable without js, by bringing in line.svg as the background for .line elements and using my css to animate it, but it's bed-time :)...

svg width in morphing animation

Hell0, I can't get my svg to take the whole width of the screen!
it doesn't matter if they are distorted or not because the idea of this use is a kind of morphing to change the background color of my page
here is my css:
.container {
height: 5000px; /* hauteur de la page */
}
.img {
width: 100%;
height: 100vh;
object-fit: fill;
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;
transition: opacity 0s ease-in-out;
opacity: 0;
}
.img.transition {
transition: opacity 0s ease-in-out;
}
.img.active {
opacity: 1;
}
the complete code is here : codepen
Thank you

I think adding viewBox parameter to your svg's might help. The 3th and 4th number give it a relative width and height. In the example below, giving it 100% w x h.
Check this out for more info -> https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/viewBox
Also you cannot use the same CSS properties for HTML nodes, also for SVG. Properties like object-fit, margin, position,etc... wil not work on SVG elements, unfortunately.
More info on that here -> https://css-tricks.com/svg-properties-and-css/
<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
<circle cx="50" cy="50" r="50" />
</svg>

Transform transition on button makes child SVG jump position at beginning and end of transition

I am currently creating a Stencil component library and one of the components is a navigation button which has an SVG icon that scales on hover to give a pop effect. To achieve this effect I put a scale transform on the SVG with an ease transition.
The problem is that when I hover over the button, just before the transitions starts, the icon jumps on some of the buttons instances (pretty randomly, depending on where on the page the button is on the page sometimes up, down, left and right) and then when the transient has ended it jumps back (sometimes not even the same amount or direction as the first jump)
<my-element></my-element>
<my-element></my-element>
<my-element></my-element>
<script>
customElements.define("my-element", class extends HTMLElement {
constructor() {
super()
.attachShadow({mode: "open"})
.innerHTML = `
<style>
:host {
display: inline-block;
}
button {
display: block;
border-radius: 8px;
margin: 0;
padding: 0.6rem;
border: none;
cursor: pointer;
}
svg {
display: block;
width: 4rem;
height: 4rem;
padding: 0;
margin: 0;
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
transition: all 1s ease;
transform: scale(1);
}
:host(:not([active]):not([disabled])) button:hover svg {
transform: scale(1.2);
}
</style>
<button disabled={this.disabled}>
<svg>
<use href="#circ">
<?xml version="1.0" encoding="UTF-8"?>
<svg height="24" width="24">
<symbol viewBox="0 0 24 24" id="circ">
<circle cx="12" cy="12" r="12" stroke="none" stroke-width="3" fill="red" />
</symbol>
</svg>
</use>
</svg>
</button>`;
}
});
</script>
This problem is browser agnostic and I've tried for quite a few hours now to figure out what's causing it. It seems removing all padding and margins resolves the issue but that's not really a solution. What I find very strange is if I put the sag inside of a collared div and add the scale transition to the div instead of the SVG, the div scales smoothly without the jump, but the SVG inside the div does the same weird jumps.

Inline elements behave differently than block elements when it comes to transitions/animations. Your div is a block element whereas the svg is an inline one.
Try to make the svg an inline-block element, or stick on a block element to achieve it.
svg {
display: inline-block;
}

Loading Square on the border of image using CSS or JS

Thank you for reading this I want a square which will load in 2 seconds around a image of 50x50
Loading Square image:
From above image the middle one is a image of height=50 and width=50, and the red colour border is loading square .
whenever anyone hover on that image that red colour square will start loading around the image and after 2 second it will complete

You could use a SVG and animate a path around an inner image, e.g.
The direction of the effect is dependent on how you build the path
svg {
cursor: pointer;
border: 1px dashed #ccc;
width: 150px;
height: 150px;
background: url(https://i.ibb.co/qdngFNL/Screenshot-2019-06-07-at-11-45-55.png) center no-repeat / 50px 50px;
}
svg:hover path {
animation: dash 2s linear 0s forwards;
}
svg path {
stroke-dasharray: 770;
stroke-dashoffset: 770;
}
#keyframes dash {
to {
stroke-dashoffset: 0;
}
}
<svg viewBox="0 0 200 200">
<path d="M2 12L2 188 Q 2,198 20,198 L 188 198 Q198,198 198,188 L198 12 Q198,2 188,2 L12 2 Q2,2 2,12z" stroke="red" stroke-width="4" fill="none"/>
</svg>
Also, for the sake of accessibility remember to add an aria-label/aria-describedby attribute if you need to convey useful information to the user, otherwise add a role="none" (or "presentation") to hide this element from assistive tecnologies.

How do I make my SVG mobile responsive

I wanted to make a svg animation for a website. But the svg is not mobile responsive. It stretches out of the background and thus making the width of the website go beyond what I intended. I think most likely that I'm doing something wrong with the viewport or width and height but I can't figure out where it's wrong.. Moreover it looks fine on desktop when I minimize the chrome browser to a mobile screen width size but when I actually open in mobile, it doesn't look the same.. Any help would be appreciated.

Moved the width and height of the svg element out of the inline styling, added max-width: 100% for responsiveness and some background for easier demonstration.

Besides a lightbox, I also have a special galleri slider (showing 8 photos on the first slide and the rest on the second). In each side, there is an arrow (left and right). They both have an hover effect (standard:opacity 0.5. Hover: 1;) But when we are on slide 1, I dont want left arrow to have the hover effect. When I scroll to slide 2, I want the left arrow to get its hover effect and the right arrow should get the hover effect removed.

How can i do this with jQuery?
Thanks!

You could simply toggle an hover class for your two arrow.
CSS:
.hover:hover {
opacity: 1;
transition: opacity 0.4s ease;
}
JS:
initial page load:
$(function(){
$(".navArrowRight").addClass("hover");
});
on page change:
$(".navArrowRight").toggleClass("hover");
$(".navArrowLeft").toggleClass("hover");
with this, your code should look like:
'use strict';
$(document).ready(function() {
$(".navArrowRight").addClass("hover");
$('.navArrowRight').click(function (){
$('#galleri_container').animate({'margin-left':'-105.5%'}, 1000);
$(".navArrowRight").toggleClass("hover");
$(".navArrowLeft").toggleClass("hover");
});
$('.navArrowLeft').click(function (){
$('#galleri_container').animate({'margin-left':'0'}, 1000);
$(".navArrowRight").toggleClass("hover");
$(".navArrowLeft").toggleClass("hover");
});
});
UPDATE
This won't work with SVG since JQuery has a problem with it.
Use this instead with SVG tag:
'use strict';
$(document).ready(function() {
$(".navArrowRight").attr("class","navArrowRight hover");
$('.navArrowRight').click(function (){
$('#galleri_container').animate({'margin-left':'-105.5%'}, 1000);
toggle();
});
$('.navArrowLeft').click(function (){
$('#galleri_container').animate({'margin-left':'0'}, 1000);
toggle();
});
});
function toggle(){
if($(".navArrowRight").attr("class") == "navArrowRight"){
$(".navArrowRight").attr("class","navArrowRight hover");
$(".navArrowLeft").attr("class","navArrowLeft");
} else {
$(".navArrowRight").attr("class","navArrowRight");
$(".navArrowLeft").attr("class","navArrowLeft hover");
}
}

You can do this with jQuery, but you can also do it with CSS, using nested rules. If you create a CSS class for each slide, then you can have two sets of hover rules, something like:
.firstPane .navArrowLeft:hover {
opacity: 1;
transition: opacity 0.4s ease;
}
.secondPane .navArrowRight:hover {
opacity: 1;
transition: opacity 0.4s ease;
}
Add the classes "firstPane" and "secondPane" to the panes, respectively. That way, the hover effects are applied selectively, depending on which pane you have. You could also use jQuery .addClass() and removeClass(), depending on when each pane is focused

Try this:
$(document).ready(function() {
var $arrowRight = $('.navArrowRight')
, $arrowLeft = $('.navArrowLeft')
;
$arrowRight.click(function () {
var $this = $(this);
$('#galleri_container').animate({'margin-left':'-105.5%'}, 1000, function() {
$arrowLeft.removeClass('hover');
$arrowRight.addClass('hover');
});
});
$arrowLeft.click(function () {
var $this = $(this);
$('#galleri_container').animate({'margin-left':'0'}, 1000, function() {
$arrowRight.removeClass('hover');
$arrowLeft.addClass('hover');
});
});
});
For this given CSS:
.navArrowLeft.hover:hover {
opacity: 1;
transition: opacity 0.4s ease;
}
.navArrowRight.hover:hover {
opacity: 1;
transition: opacity 0.4s ease;
}
