Free live HTML authoring tool with context specific inline CSS editor
When editing HTML and CSS, normally I use Visual Studio which has great intellisense and automatic formatting. I've been using OS X a lot recently and wanted to find a similar editor that was Mac compatible. I was keen to find something free as my HTML authoring needs are fairly light. I stumbled upon a great little open source editor called Brackets by Adobe. Brackets has the usual colour coding and automatic formatting as well as intellisense. What makes it differ from the rest is live preview capability so you can see your code changes in the browser as you type. It also has an inline CSS editor so, at the press of a button, you can see and edit the relevant CSS rules applied to a selected HTML element (see screenshot above). Pretty impressive for a free piece of software!
