Brackets for Mac is an open source code editor for HTML, CSS, and JavaScript built on top of HTML, CSS, and JavaScript.

Brackets for Mac comes with a clean user interface called Quick Edit UI. This is where you place context-sensitive code and edit it with built-in tools, instead of cluttering your coding environment with various panels and icons.

It also has a very useful feature called Live Preview that works directly with your browser to make code changes instantly. You can switch between source code and browser view.

Brackets for Mac is a robust editor that has everything you need to work with files and directories, as well as create new files. Code completion features allow you to quickly assemble applications without knowing the exact syntax. If you need helper code syntax and code options, the Quick Edit option will help you with that.

Brackets for Mac also offers a powerful extension framework. There are many extensions available that can be viewed and installed using the extension manager located in the File menu or by clicking the icon in the top right corner of the main interface.

Overall, Brackets for Mac is easy to use and a pleasure to code. The interface is easy to navigate and the extensions offer a lot of options. The Live Preview option is a really useful tool because you get instant feedback on any changes to your code.

Best of all, according to Adobe, because Brackets for Mac is open source and built with HTML, CSS, and JavaScript, with it you can help build the best code editor for the web (if you want).
