This is the second part of our “Resources for WordPress Theme Designers” series, last time out we looked at Free Font Icons. This time I am going to be looking at tools to help with your CSS development. With the introduction of CSS3 things got a little more complicated and much more powerfull for web designers and there is a whole load of new tools to make your life easier and help you get to all the new features.

CSS3 Generator

CSS3 Transforms

One of the most powerful features of CSS3 are transforms, which allow us to take any element in an HTML document, and while not changing its effect on the page layout, rotate it, translate it (move it left, right, up and down), skew it and scale it.


Modernizr is a JavaScript library that detects HTML5 and CSS3 features in the user’s browser.


Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.


LESS extends CSS with dynamic behavior such as variables, mixins, operations and functions. LESS runs on both the client-side (Chrome, Safari, Firefox) and server-side, with Node.js and Rhino.
