Problem
I'm trying to simply move an svg element using transform=matrix(a,b,c,d,e,f)
The element is moving fine but when I apply a css transition it has no effect.
Question
Is this possible on svg elements without an external library like d3?
Code I'm trying
html:
<svg width="100%" height="100%" viewbox="0 0 200 200">
<rect x="20" y="20" width="50" height="50"
style="fill: #3333cc"
transform="matrix(1,0,0,1,1,1)"
id="blueBox"
/>
</svg>
<button id="boxMover">
Move it
</button>
jQuery
$(function(){
$('#boxMover').click(function(){
var blueBox = $('#blueBox');
if(blueBox.attr('transform')=='matrix(1,0,0,1,1,1)'){
blueBox.attr('transform', 'matrix(1,0,0,1,100,30)');
} else {
blueBox.attr('transform', 'matrix(1,0,0,1,1,1)');
}
})
})
CSS
svg {
display: block
}
#boxMover {
position: absolute;
left: 20px;
top: 20px;
transition: transform .5s ease;
}
Here's a fiddle I created to test it
A simpler solution:
Create the following class:
.boxEase {
transform: matrix(1,0,0,1,100,30);
transition: all .5s ease;
}
Change your jQuery code to just attach the above class to your box when the button is clicked:
$(function(){
$('#boxMover').click(function(){
var blueBox = $('#blueBox');
blueBox.attr('class', 'boxEase');
})
})
Added dynamic case with variable ending (starting) positions
Use the following jQuery code where transform and transition properties are added to the box conditionally. I imagine you can adjust the conditional to something else but I have used your original example for this case:
`$(function(){
$('#boxMover').click(function(){
var startPos = 'matrix(1,0,0,1,1,1)',
endPos = 'matrix(1,0,0,1,100,30)';
var blueBox = $('#blueBox');
if(blueBox.attr('transform') == startPos){
blueBox.attr('transform', endPos);
blueBox.css({'transform': endPos, 'transition': 'all 0.5s ease'});
} else {
blueBox.attr('transform', startPos);
blueBox.css({'transform': startPos, 'transition': 'all 0.5s ease'});
}
})
}); `
There's a horrible grey area between the CSS and SVG namespaces where things like this happen all the time.
However, you can fix your problem as follows:
Move the transform CSS statement out of the #boxMover rules and put it somewhere it can actually affect the behaviour of your #blueBox SVG element.
Changing the transform attributes of the SVG element directly still won't work because you're talking to the SVG namespace, and the CSS rules aren't having any say in the matter. Instead, set up CSS classes containing the required transform attributes, and switch between those instead. There is no class attribute in the SVG namespace, so the CSS rules will come to life.
Also note that you can't use JQuery's addClass() and removeClass() methods to change the class of an SVG element, so use attr('class') instead
This should work:
$(function() {
$('#boxMover').click(function() {
var blueBox = $('#blueBox');
if (blueBox.attr('class') == 'overHere') {
blueBox.attr('class', 'overThere');
} else {
blueBox.attr('class', 'overHere');
}
})
})
svg {
display: block
}
#boxMover {
position: absolute;
left: 20px;
top: 20px;
}
#blueBox {
transition: transform .5s ease;
}
.overHere {
transform: matrix(1, 0, 0, 1, 1, 1);
}
.overThere {
transform: matrix(1, 0, 0, 1, 100, 30);
}

I've this wordpress site uses matter.js and SVG animation with CSS. It gets heat up very quickly and sometimes exhausted the browser. The web server will go down once in a while for a few minutes too but I'm not sure if is correlated.
I've included a start/stop button to enable animation only when the user clicks instead of running it concurrently with the page loads. This does help a little.
I upgraded the machine type and it seems to solve the downtime issue however it is very expensive to keep. Considering the website is only using 10% of the resources and Google Cloud's recommender suggested to switch to a lower machine type to save 50% of the cost.
Are there ways I can improve the CSS animation?

I have a simple SVG image. There is a circle inside which I would like to rotate 90 degrees. But as you can see in JSFiddle example center of the rotation is not in the middle. What am I doing wrong?
svg {
background-color: #ddd;
}
.circle1 {
fill: none;
stroke-width: 20px;
stroke: #b5b5b5;
}
.circle2 {
fill: #aaa;
transform: rotate(-20deg);
stroke-width: 15px;
stroke: #71c7ff;
}
<svg height="600" width="600">
<circle class="circle1" cx="300" cy="300" r="200"></circle>
<circle class="circle2" cx="300" cy="300" r="200"></circle>
</svg>
Here is JSFiddle example https://jsfiddle.net/oxt681gr/1/
By default, the origin of a transform should be 0px 0px, but now we have wrong info on MDN:
By default, the origin of a transform is center.
Source-link
It is wrong. But in the case if it would be in center of your circle you would not able to see the result of your rotation because you will rotate the circle in his center.
You can change the rotation center with CSS property transform-origin or with SVG transform attribute. In SVG transform attribute we have the default also on 0px 0px. To rotate SVG (without CSS) use transform="rotate(deg, cx, cy)", where deg is the degree you want to rotate and (cx, cy) define the center of rotation.
In my solution you can change it interactive with CSS and JS:
var input = document.querySelector('input'),
circle2 = document.querySelector('.circle2'),
output = document.querySelector('span');
input.onchange = function(e)
{
var newTransformOrigin = e.target.value;
output.innerHTML = newTransformOrigin + 'px' + ' ' + newTransformOrigin + 'px';
circle2.style.transformOrigin = output.innerHTML;
};
svg {background-color:#ddd}
.circle1 {fill: none; stroke-width: 20px; stroke: #b5b5b5}
.circle2
{
fill: #aaa;
transform-origin: 0 0;
transform: rotate(-20deg);
stroke-width: 15px;
stroke: #71c7ff;
}
<p>Change transform-origin <input type="range" min="0" max="600" value="0" step="50">
<span>0px 0px</span></p>
<svg height="600" width="600">
<circle class="circle1" cx="300" cy="300" r="200"></circle>
<circle class="circle2" cx="300" cy="300" r="200"></circle>
</svg>

I have a div with an SVG background. The div height and width do not change. The only thing that changes is the SVG file used for the background when the div is hovered.
The issue seems to be that when the SVG background is replaced (even after the asset is preloaded) the image seems to "shake" before settling into place. I've triple checked and both SVG assets are the exact same height and width and viewport, the only difference is the coloring.
For reference, the issue can be seen on this page: https://tqt.uwaterloo.ca/.
When hovering the "hamburger" icon the issue can be seen.
When hovering the "search" icon there is no issue, however the "search" icon has the exact same SVG replacement on it and it's working as expected.
Final note: This issue is only replicatable on retina (2x+) monitors.
There are two bugs here, one in Blink (Chrome and Chromium based browsers) and one in webkit, both caused by the transitioning of the background-image property.
Here is a minimal repro of these bugs:
const svg = `<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 34 26">
<path d="M0,0h34v4H0V0z M0,22h34v3.9H0V22z M0,11h34v4H0V11z" fill="black"/>
</svg>`;
const url = 'url(data:image/svg+xml,' + encodeURIComponent( svg ) + ')';
const urls = [ url, url.replace( 'black', 'red' ) ];
let i = 0;
setInterval(() =>
document.querySelector( '.burger' ).style.backgroundImage = urls[ (++i % 2) ],
500
);
.burger {
height: 30px;
width: 100px;
background-position: center;
background-repeat: no-repeat;
transition: background-image .2s linear;
}
<div class="burger">
</div>
Chrome's bug is due to the fact your svg files don't have their own width and height attributes, setting one will fix it there.
Safari bug is caused by the retina scaling, on which they weirdly apply the transition too... For this one a fix would be harder, but setting the correct height will make it less visible since we'd only have antialiasing artifacts to move.
Here is the same snippet as above, with just the height and width attributes set:
const svg = `<svg width="34" height="26" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 34 26">
<path d="M0,0h34v4H0V0z M0,22h34v3.9H0V22z M0,11h34v4H0V11z" fill="black"/>
</svg>`;
const url = 'url(data:image/svg+xml,' + encodeURIComponent( svg ) + ')';
const urls = [ url, url.replace( 'black', 'red' ) ];
let i = 0;
setInterval(() =>
document.querySelector( '.burger' ).style.backgroundImage = urls[ (++i % 2) ],
500
);
.burger {
height: 30px;
width: 100px;
background-position: center;
background-repeat: no-repeat;
transition: background-image .2s linear;
}
<div class="burger">
</div>
Now, there should probably be a note that if targeting only quite recent browsers is not an issue for you, you could achieve the same effect by using only CSS filters, saving one network request:
const svg = `<svg width="34" height="26" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 34 26">
<path d="M0,0h34v4H0V0z M0,22h34v3.9H0V22z M0,11h34v4H0V11z"/>
</svg>`;
// This time we generate only a single black url
const url = 'url(data:image/svg+xml,' + encodeURIComponent( svg ) + ')';
document.querySelector( '.burger' ).style.backgroundImage = url;
.burger {
height: 30px;
width: 100px;
background-position: center;
background-repeat: no-repeat;
transition: filter .2s linear;
}
.burger:hover {
/*
Using formula from
https://stackoverflow.com/a/43959856/3702797
to safely fallback on black for browsers withtou support for filters
*/
filter: invert(10%) sepia(100%) saturate(10000%) ;
}
hover the icon to change its color.
<div class="burger">
</div>
I need to change SVG fill property by adding up a class. Say from #fff to #000. I tried fiddling with two different methods. I got successful with one of either method. Rather I don't prefer the method to use which I was successful.
Method 1: - Succesful.
I just added a class on the body tag and over-ride the svg fill property. Take a look at the code below
var button = document.getElementById("btn");
var body = document.body
var count = false;
button.onclick = changeBackground;
function changeBackground() {
body.classList.toggle('toggle');
}
body {
background: #3d3d3d;
}
.sheetListWhite {
fill: #fff;
}
.slBGColor {
fill: #3d3d3d;
}
.toggle {
background: #fff;
}
.toggle .sheetListWhite {
fill: #3d3d3d;
}
.toggle .slBGColor {
fill: #fff;
}

Fiddle it HERE
Now you can see I can't override the following classes .slBGColor, .sheetListWhite
How can I get rid of this bug? Any Idea. I don't want to use the svg tag directly instead of use tag. I mean I would like to use all of my SVG from an external resource. Any Help
Thanks.
The "insides" of a <use> cannot be addressed via the <use> element. It is considered opaque/private. As far as the browser is concerned, there is no class="slBGColor" inside the <div>. So .toggle .slBGColor {} does nothing.
You can make it work by restyling the symbol definition itself.
For example, if I make the following two changes to your example, the ellipse in the symbol changes colour based on whether the "toggle" class is set or not.
var body = document.body;
.toggle div {
background: red;
}

However, be aware that will also change any other references to that symbol on the page.
I am having troubles to scale the SVG to fit the window size.
In this example, I have a wavy path and a text element, what I want to achieve here is to move the text element along the wavy path from left to right (which is done by GSAP) and stop in the half way of the path in the initial load; it will move to the end when users start scrolling.
My problem is that, the wavy path created by SVG is too long, even the half way of the path will be off the window, I tried to scale down the wavy path by using viewBox, failed; using css width: 100vw, failed.
I also used the css transform property, it did scale the wavy path down, but that was a fixed size, I want to make it as responsive as possible, which means regardless the window width, the text element always stops in the middle of the screen first ( half way of the wavy path ), then moves to the right hand side of the screen. Is this possible when using inline SVG element? If so, please point me in the right direction.
Thank you in advance!
(Please view the example in full page mode, that will explain my problem perfectly, but the scroll function will be disabled because the height in that mode is 100vh, there is no room for scrolling)

If you want your SVG to scale to fit the screen (or any parent container), it needs to have a viewBox attribute. This attribute tells the browser the dimensions of the SVG content. Without it, the browser has know way of knowing how much it needs to be scaled.
Your path is about 3780 width, and the bottom of it is at y=144. So a reasonable value of viewBox would be:
viewBox="0 0 3780 150"
document.getElementById("MyPath").setAttribute("d", document.getElementById("Path").getAttribute("d"));
var tl = new TimelineMax({
repeat: 0,
delay: 1
});
tl.to("#Text", 3, {
attr: {
startOffset: '50%',
opacity: 1
}
});
window.addEventListener('scroll', function() {
tl.to("#Text", 3, {
attr: {
startOffset: '100%',
opacity: 0
}
});
}, true);

Here's what you could do: add a media query defining the desired width and then apply the following styles separately for the text and path elements inside the svg element:
text {
font-size: 2em;
}
path {
-webkit-transform: scale(.3);
-ms-transform: scale(.3);
transform: scale(.3);
}
See the snippet below:
document.getElementById("MyPath").setAttribute("d", document.getElementById("Path").getAttribute("d"));
var tl = new TimelineMax({
repeat: 0,
delay: 1
});
tl.to("#Text", 3, {
attr: {
startOffset: '50%',
opacity: 1
}
});
window.addEventListener('scroll', function() {
tl.to("#Text", 3, {
attr: {
startOffset: '100%',
opacity: 0
}
});
}, true);
