Styles allows you to edit the appearance of themes that don't provide an interface in the WordPress admin for doing so. Themes supported by the free version include:

• TwentyTen
• TwentyEleven

Theme support is provided by a remote API, so the plugin will update as more themes are added. We plan to release support for more themes in as a paid add-on to Styles. Have a specific theme you'd like to see supported? Vote on themes here.

Styles provides:

• Transfer of settings between themes
• Background images using WordPress Media Library
• Photoshop-like Gradient Picker
• Color Picker
• Google Fonts
• Font size, color, styling, and capitalization
• Replace HTML elements with an image
• Live preview when site open in a second window

Enable the plugin to start playing with your site's look under Appearance > Styles.

This plugin requires PHP 5.2, the minimum supported version as of WordPress 3.2.
