programmatically changing webkit-transformation values in animation rules

Question

I have this stylesheet:

        @-webkit-keyframes run {
            0% {
                -webkit-transform: translate3d(0px, 0px, 0px);
            }                


        

Answer 1

I didn't get when you wanted to modify these values (i.e. use variables) but nevertheless here are 3 to 4 solutions and 1 impossible solution (for now).

• server-side calculation: in order to serve a different CSS from time to time, you can tell PHP or any server-side language to parse .css files as well as .php or .html and then use PHP variables in-between PHP tags. Beware of file caching: to avoid it, you can load a stylesheet like style.css?1234567890random-or-time it will produce an apparent different file and thus won't be cached

• SASS is also a server-side solution that needs Ruby and will provide you an existing syntax, probably cleaner than a hand-made solution as others have already about problems and solutions

• LESS is a client-side solution that will load your .less file and a less.js file that will parse the former and provide you variables in CSS whatever your server is. It can also work server-side with node.js

• CSS being dynamically modified while your page is displayed?
  For 2D there are jquery-animate-enhanced from Ben Barnett, 2d-transform or CSS3 rotate are pitched the other way around (they use CSS3 where possible and where there are no such functions, they fallback to existing jQuery .animate() and IE matrix filter) but that's it.
  You could create a plugin for jQuery that would manage with a few parameters what you want to achieve with 3D Transformation and avoid the hassle of modifying long and complex CSS rules in the DOM

• CSS only: you could use -moz-calc [1][2] that works only in Firefox 4.0 with -webkit-transform that works only in ... OK nevermind :-)
