CSS3 for SASS

This is a simple SASS file that provides a number of useful mixins to achieve CSS3 effects cross-browser. For each rule, the styles are implemented for as many browsers as possible.

DISCLAIMER: this gist is not ready. I forked it to develop a more useful mixin list, but discovered some mixins are behaving other than expected. Needs rework. Use at your own risk!

	How to print a string in both (or more) languages when using qTranslate on Wordpress

	qTranslate provides Wordpress with multilanguage support and automates this in a pleasant way.
	However you might want to print a specific string in a specific language, somewhere in your
	theme or module.
	Use this function to extract the content from the qTranslate quicktags, and retrieve the
	title directly from the database using this query.
