The main gradient control allows you to:

  • » Add a new stop by clicking anywhere in between the existing stop markers

You can use the ‘Stops’ panel to conrol the color and the position of the currently selected stop more precisely.

The ‘Preview’ panel allows previewing the current gradient as a vertical or horizontal one, and also allows quickly previewing how the Internet Explorer fallback gradient will look in IE.

Finally, the ‘CSS’ panel always has the CSS for the current gradient for easy copying and pasting into your stylesheet. You can also use this panel to import an existing gradient CSS into the tool.


The ‘Ultimate Web 2.0 Gradients’ preset gradients were derived from work by deziner folio and SGlider12.

The Color Picker is a minor adaptation of John Dyer’s Color Picker.

The Base-64 encoder function is from webtoolkit.
