HOWTO: Use CSS3 animations
- 1. Include the CSS3 animations file
- 2. Add the relevant CSS class to your canvas tag
- Using CSS3 animations with the textAccessible option
- Note about using window.onload with animations
CSS3 animations are a very efficient way to add effects to your charts. Browser support is good (Chrome, Firefox, Opera, Safari, IE10+) and there are a lot of effects available. You can chain the effects by setting two to run sequentially.
The CSS3 effects library is available in the
css folder of the download archive and it is authored by Daniel Eden.
1. Include the CSS3 animations file.
Including the CSS3 file is a simple matter of adding a <link> tag to your page header.
<link rel="stylesheet" href="animations.css" type="text/css" media="screen" />
animate.css file is quite large (over 60k) so if you
only use certain effects from it you can take those effects
out of the file and put them in your own CSS file. The front page of
this website used to do this and, compressed (using
gzip), the CSS that was
necessary for the effect that was used (a modified

2. Add the relevant CSS class to your canvas tag
This is just a case of adding a
class="" attribute to your canvas tag.
<canvas id="cvs" width="600" height="250" class="animated rotateIn">[No canvas support]</canvas>
Using CSS3 animations with the textAccessible option
If you're using CSS effects with the
then you need to add the relevant CSS class to a wrapper DIV
like the code shown here:
<div style="display: inline-block; width: 600px; height: 250px" class="animated rotateIn"> <canvas width="600" height="250" id="cvs">[No canvas support]</canvas> </div>
<script> var div = document.getElementById('cvs').parentNode; div.className = ''; div.className = 'animated hinge'; </script>
Note about using window.onload with animations
If you're missing part of your animation then it may be due to the
window.onload event. If your canvas tag is near the top
window.onload event, which may not be triggered immediately, you may end up not seeing the start of your animation
effect. You can mitigate this by using jQuery to add the appropriate CSS classes after the call to the
Also, as a general rule, the jQuery
ready event (which utilises the underlying standard
DOMContentLoaded event) will
result in your charts being displayed quicker than the
