GTK+ is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off projects to complete application suites.

GTK+ is free software and part of the GNU Project. However, the licensing terms for GTK+, the GNU LGPL, allow it to be used by all developers, including those developing proprietary software, without any license fees or royalties.

GTK+ has been designed from the ground up to support a range of languages, not only C/C++. Using GTK+ from languages such as Perl and Python (especially in combination with the Glade GUI builder) provides an effective method of rapid application development.

Checking your CSS can be a real pain, if you don't have the proper tools. Free CSS Toolbox gives you the essentials to take care of the job in seconds. After having tested it we concluded that it had all the tools you would really need, like automatic check, reformat and the most important, validation of CSS. All you have to do is paste or open your code in Free CSS Toolbox to get working on it. We also liked the compress tool, which reduces your CSS to the max, ridding it of unnecessary code. The program also features all the shorthand properties you need, like borders, background or padding.

Free CSS Toolbox is not an extremely advanced application, but it'll cater to those looking for a no-fuss add. Even they're discreet, we were a bit annoyed by the ads for other apps like Rapid CSS editor. On the whole though, Free CSS Toolbox is a simple program to quickly correct your CSS and best of all, it's free.
