SVG Animations Very Laggy after Resizing (Expert)? - javascript
So I am adding an SVG to my website. I am also resizing this svg to fit most of my screen, by changing a class called "background-svg" that you'll see in my code below.
Basically, If you make the SVG bigger, it becomes super laggy (like its animations are super laggy) and even other animations on the page become super laggy. Try On JSFIDDLE
If you make the SVG small, the animations are Smooth. On the JSFIDDLE link above, try making your window smaller (you'll see the animations are better), then make your window bigger (laggy animations again).
Problem Only Occurs on Chrome and Safari...No Lags on FireFox

TL;DR: Super Laggy SVG Animations if SVG is large, but smooth animations if SVG is small.
This has to do with GPU usage when animating with pure CSS. Although most properties like transform are 'GPU injected' this isn't a guarantee. If you were to do this with JavaScript; you may see significant performance enhancements.
I do not get much 'lag' at all while running these animations.
This article is specific to a JS animation library, but clearly explains this concept as well.
How CSS animations are rendered
As far as performance changing with window scaling, it has to do with the number of pixels being altered/rendered with each animation cycle.
For example, if you're vector SVG draws a shape on a 500x500px canvas that takes up 75% of the area, you're going to be drawing alot less pixels in then if you have a 2000x2000px canvas with a shape that takes up 75% of the area.
Since this is calculated over and over again then redrawn when you're using an SVG, there can be a significant performance difference when scaling up.
Since browsers are built and render differently, FireFox is simply able to handle the redrawing of these shapes over and over better than the other browsers in this circumstance.
I've noticed two main issues:
the order of the css properties: transform and transition properties are after the vendor-specific ones, so I put it before them
the use of the 2D transformations, which don't exploit hardware acceleration, so I changed them with the equivalent 3D ones
The following snippet contains part of what I've modified, you can try it in this fiddle and give me a feedback
#Triangle-2 {
animation: box2 1s infinite;
-o-animation: box2 1s infinite;
-moz-animation: box2 1s infinite;
-webkit-animation: box2 1s infinite;
}
#keyframes box2 {
10% {
transform: rotate(1deg);
-o-animation: rotateZ(1deg);
-moz-animation: rotateZ(1deg);
-webkit-transform: rotateZ(1deg);
}
90% {
transform: rotate(-2deg);
-o-animation: rotateZ(-2deg);
-moz-animation: rotateZ(-2deg);
-webkit-transform: rotateZ(-2deg);
}
}
I've worked with html elements translations in the past, and in my case the 3D css solution outperformed the 2D and the javascript ones, mostly because of the hardware speed up without passing through the javascript interpreter.
If you want take a look here to have more details about hardware accelerations and comparison with javascript solutions.

Consistent filling of SVG's rectangles
How to make each of these squares filled with red colour consistently left to right; and when one filled with red, previous will have default colour?
#foo > rect {
height: 32px;
width: 32px;
}
<svg id=foo height=32 width=160>
<rect x=0 y=0 />
<rect x=64 y=0 />
<rect x=128 y=0 />
</svg>
This animation must be repeatable.
If you are open to a CSS solution you can simulate such effect using background animation where you can easily scale to any number of square but without fading:
.rect {
height: 32px;
width:calc(40px*10); /* 10 Squares*/
background:
/* This gradient will make the red color to fade from the first to the last*/
linear-gradient(red,red) 0 0/32px 100% no-repeat,
/* This gradient will create the squares (32px of black then 8px of transparent)*/
repeating-linear-gradient(to right,black 0 32px,transparent 32px 40px);
margin:0 5px;
animation:change 10s steps(10) infinite;
}
#keyframes change{
to {
background-position:calc(100% + 32px) 0,0 0;
}
}
<div class="rect"></div>
With CSS variable you can control the different values:
.rect {
--s: 32px; /* Square size */
--nb: 10; /* Square number */
--gap: 8px; /* gap between squares */
--c1:black;
--c2:red;
height: var(--s);
width:calc((var(--gap) + var(--s))*var(--nb));
background:
linear-gradient(var(--c2),var(--c2)) 0 0/var(--s) 100% no-repeat,
repeating-linear-gradient(to right,var(--c1) 0 var(--s),#fff var(--s) calc(var(--s) + var(--gap)));
margin:5px;
animation:change calc(var(--nb)*1s) steps(var(--nb)) infinite;
}
#keyframes change{
to {
background-position:calc(100% + var(--s)) 0,0 0;
}
}
<div class="rect"></div>
<div class="rect" style="--nb:8;--s:50px;--c1:green;--c2:yellow"></div>
<div class="rect" style="--nb:15;--s:10px;--c2:blue"></div>
Use CSS keyframes:
#foo > rect {
height: 32px;
width: 32px;
animation: anim 3s infinite;
}
#foo > rect:nth-of-type(1){
animation-delay: 0s;
}
#foo > rect:nth-of-type(2){
animation-delay: 1s;
}
#foo > rect:nth-of-type(3){
animation-delay: 2s;
}
#keyframes anim{
0% { fill: black; }
50% { fill: red; }
100% { fill: black; }
}
<svg id=foo height=32 width=160>
<rect x=0 y=0 />
<rect x=64 y=0 />
<rect x=128 y=0 />
</svg>
CSS/JS: CPU lightweight loading spinner
I am designing a Node.js application to perform tasks that take a variable amount of time. While the application performs those tasks I want to display a loading spinner. However my loading spinner taxes the CPU much more than I expected. Viewing my CPU usage in Task Manager, at idle my program is ~1% but with a single loading spinner visible it rockets up to >36% (in electron, Task Manager shows about 12% CPU use in Chrome).
This is unacceptable because the spinner can be on screen for greater than ten minutes and my poor laptop starts to overheat. I have tried using .gif images and pure css solutions as an alternative to rotating svgs but both methods also use too much of the CPU.
Is there a lightweight solution (~3% CPU maximum) to create a spinner like the snippet shown below?
<svg width="64px" height="64px" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100" preserveAspectRatio="xMidYMid" class="lds-rolling" style="shape-rendering: auto; animation-play-state: running; animation-delay: 0s; background: red;"><circle cx="50" cy="50" fill="none" ng-attr-stroke="{{config.color}}" ng-attr-stroke-width="{{config.width}}" ng-attr-r="{{config.radius}}" ng-attr-stroke-dasharray="{{config.dasharray}}" stroke="#ffffff" stroke-width="10" r="35" stroke-dasharray="164.93361431346415 56.97787143782138" style="animation-play-state: running; animation-delay: 0s;" transform="rotate(179.618 50 50)"><animateTransform attributeName="transform" type="rotate" calcMode="linear" values="0 50 50;360 50 50" keyTimes="0;1" dur="1s" begin="0s" repeatCount="indefinite" style="animation-play-state: running; animation-delay: 0s;"></animateTransform></circle></svg>
If that spinner design is what you are looking for, I would suggest a pure CSS solution. Define an element that will have class spinner. Then your css might look something like this:
.spinner {
background: red;
height: 64px;
width: 64px;
border: 5px solid white;
border-radius: 50%;
border-top: 5px solid transparent;
animation: rotate 0.6s linear infinite;
}
#keyframes rotate {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
<div class="spinner"></div>
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.
IE / Edge SVG loading/rendering issue
When I open my website in Microsoft Edge, Everything looks mostly okay, except that the left-hand side of the logo does not keep time with the right-hand side -- the B comes in nice and smooth, but the S is slightly behind in timing and very jerky. Refreshed several times and it is always exactly the same. Also, if I scroll down and back up to the top in Edge, the S is sometimes only partly drawn (i,e. the bottom of it is missing) even though it was drawn completely when I first open the page.

Also, the graph/circle animations work, but they don't do exactly the same thing as they do in Chrome. In Chrome the circles do a full 360 degrees before coming to their final positions, in Edge they just go from the top to their final position (i.e. only turn 270°, 180° or 90°).

Anyone know how to fix these issues?

Svg scale path at a center point (pulsating)
I am trying to animate several paths in an svg around two circles. My goal is to scale the paths at center, as if they were pulsating. I've looked at every answer on stackoverflow to figure out how to achieve this. The closest solution I have found did not wok.
Here is a jsfiddle of what I have so far. As you can see, the paths are scaling away/towards the origin. If there is no way to achieve this with CSS, is it possible to achieve this with a javascript framework like Velocity.js?
This is the SVG:

And here is the CSS:

text-align: center;
}
.icon-sun-beam {
animation-name: scale;
animation-duration: 3s;
animation-iteration-count: infinite;
transform-origin: 50px 50px;
animation-timing-function: linear;
animation-fill-mode: both;
animation-direction: alternate;
}
.icon-sun-beam:nth-child(even) {
animation-delay: 4.5s, 4.5s;
}
.icon-sun {
animation-name: rotate;
animation-iteration-count: infinite;
animation-duration: 18s;
animation-timing-function: linear;
transform-origin: 50px 50px;
}
svg {
shape-rendering: geometricPrecision;
}
#keyframes rotate {
0% {
transform: rotate(0);
}
100% {
transform: rotate(360deg);
}
}
#keyframes scale {
0% {
transform: scale(0.85, 0.85);
}
100% {
transform: scale(1.35, 1.35);
}
}
There is a simple solution, that is cross-browser.
Just give each of your sunbeams its own absolute transform-origin.
.wrapper {
width: 100px;
text-align: center;
}
.icon-sun-beam {
animation-name: scale;
animation-duration: 3s;
animation-iteration-count: infinite;
animation-timing-function: linear;
animation-fill-mode: both;
animation-direction: alternate;
}
.icon-sun-beam:nth-child(even) {
animation-delay: 4.5s, 4.5s;
}
.icon-sun {
animation-name: rotate;
animation-iteration-count: infinite;
animation-duration: 18s;
animation-timing-function: linear;
transform-origin: 50px 50px;
}
svg {
shape-rendering: geometricPrecision;
}
#keyframes rotate {
0% {
transform: rotate(0);
}
100% {
transform: rotate(360deg);
}
}
#keyframes scale {
0% {
transform: scale(0.85, 0.85);
}
100% {
transform: scale(1.35, 1.35);
}
}

I ended up using GSAP library to animate the SVG. I chose to do this because there was no solution that would have worked without breaking the animation on either Chrome or Firefox. This is the code that I have tested which works on IE 11, Firefox and Chrome. I used Jquery and TweenMax libraries.
$(document).ready(function() {
var sun = $(".icon-sun");
var sunBeamEven = $(".icon-sun-beam:even");
var sunBeamOdd = $(".icon-sun-beam:odd");
function animateSun(){
TweenMax.to(sun, 12, {rotation:"+=360", svgOrigin:"50 50", smoothOrigin:true, repeat:-1, ease:Linear.easeNone});
TweenMax.to(sunBeamEven, 4, {scale:0.5, transformOrigin:"50% 50%", repeat:-1, yoyo:true, ease:Linear.easeNone});
TweenMax.to(sunBeamOdd, 4, {scale:0.5, transformOrigin:"50% 50%", repeat:-1, yoyo:true, ease:Linear.easeNone, delay:3});
}
animateSun();
