Stop writing code. Start drawing it
  Macaw provides the same flexibility as your favorite image editor but also writes semantic HTML and remarkably succinct CSS. It's time to expect more from a web design tool.

Fluid canvas and grid
  Macaw is engineered for fluid widths. Resize the canvas and your grids and elements will update accordingly.

Responsive Breakpoints
  Designing for different device sizes is tricky. Macaw lets you define arbitrary breakpoints and tweak properties for that specific width.

Rich Typography
  Macaw gives you access to your system fonts, a full library of web fonts and even allows you to pull in Typekit fonts. It also provides useful calculations like characters per line.

Interactivity
  Building clickable prototypes in Macaw is as easy as clicking on a target, but it doesn't stop there. You can also add more dynamic interactions with the scripting palette. Macaw will even autogenerate templates and jQuery variables for you.

Requirements:
* Intel, Mac OS X 10.7 or later.
