Find CSS Class with ability to replace
ECMAScript (JavaScript)
Changing class names is hard with a large codebase written in multiple languages. Classes can appear in several constructs. This tries to match the various ways a class can be represented in HTML. Plug the RegEx in to Sublime Text 2 using "Find in Files...". When replacing in ST2, change $1 to \1.
