Button can be manually assigned any of the button color swatches from the theme to add visual contrast with the container they sit inside by adding the data-theme attribute on the button markup and specifying a swatch letter.
All the standard button swatches can be applied to lists. The default theme is "f" (silver in the default theme).
The list item color scheme can be changed to any button color theme swatch by adding the data-theme="e" attribute to the list, and setting the letter theme swatch.

Every layout and widget in jQuery Mobile is designed around a new object-oriented CSS framework to make it possible to design complete sites and applications. The theming system is similar to the ThemeRoller system in jQuery UI but with a few important improvements:
-
Richer designs are now possible because themes now include multiple color "swatches": 4 bars with matching buttons for each, 3 content areas that can be freely mixed and matched to create visual texture
-
Open-ended theming allows for additional theme swatches can be added to a theme to add almost unlimited more variety to designs
-
All backgrounds now use CSS3 gradients to dramatically reduce file size and number of server requests
-
A simplified icon set only includes the most commonly used icons in either black or white colors to reduce image weight
+
By taking advantage of CSS3 properties to add rounded corners, box and text shadow and gradients instead of images, the theme file is very lightweight and reduces server requests.

In jQuery Mobile, there is a single theme CSS file that contains multiple color "swatches" for bars, content blocks and buttons that can be combined to achieve a wide range of visual effects. The key to the theme system used in jQuery UI is separation of color and texture (theme) from structural styles that define things like padding and dimensions. This allows the theme colors and textures to be defined once in the stylesheet as color "swatches", that can be mixed and matched. We also take advantage of CSS3 properties to add rounded corners, box and text shadow and gradients to make the theme styles very lightweight and reduce server requests.

Themes include at least 3 swatches for bars, content blocks and buttons. To make mapping of color swatches consistent across our widgets, we have followed the convention that swatch "a" is the highest level of visual priority (black in our default theme), "b" is secondary level (blue) and "c" is the baseline level (gray) that we use by default in many situations. Themes may have additional swatches but these are used for accents colors or specific situations within an app or site.

The default theme contains 4 color swatches for bars to use in header, footer and tool bars. The swatches are designated by letters (a, b, c, etc.) and are organized into a visual hierarchy where "a" is the highest level of visual priority, "b" is secondary, "c" is the baseline, and "d" is for accents. Each swatch defines the border color, text color, gradient, text-shadow, font family and link color. Our default theme looks like this:

By default, the framework assigns the "a" swatch (black in the default theme) to all headers and footer because these are typically given high visual priority in an application. To set the color of a bar to a different swatch color, simply add the data-theme attribute to your header or footer and specify a letter (a, b, c, d) and the specified theme swatch color will be applied.

Content Blocks

The default theme contains 3 color swatches for use in content blocks. These are designed to coordinate with the header color swatches in the default theme. Just as with bars, you can add as many content block swatches you want by extending the theme stylesheet. If a theme isn't specified on a content block, the framework will default to "c", just like the header.

The jQuery Mobile framework uses a single theme swatch called "active" (bright blue in the default theme) to consistently indicate the selected state, regardless of the theme of the widget. We apply this in navigation and form controls to indicate what is currently selected. Because this theme swatch is designed for clear, consistent user feedback, it is not currently a theme swatch that can be overridden via the markup. It is set once in the theme and applied by the framework whenever a selected or active state is needed. The styling for this state is in the theme stylesheet under the ui-btn-active style rules.

Buttons
A set of 4 button colors are also included in the default theme. Each button has styles for normal, hover/focus and pressed states. Each button is intentionally styled to match the color of a bar so they feel tightly integrated.
A button is automatically assigned a theme swatch letter that matches it's parent bar or content box to visually integrate the button into the parent theme, like a chameleon. To illustrate this idea, below, the same exact button code is in each of the 4 bars and is automatically setting their color swatch to match on the parent bar swatch.
This makes it really easy to ripple a theme change through a page by setting a theme swatch on a parent because you know the buttons will maintain the same relative visual weight across themes. Since form elements use the button styles, they will also adapt to their parent container too.

To add visual emphasis of certain buttons in a toolbar, the theme swatch color for a button can be set by adding a data-theme="a" to the anchor to make it stand out visually from it's parent. If the theme is set on a button in the markup, the framework won't override the theme swatch color when the parent theme is changed because you made a conscious decision to set the color.

Icons
There a core set of standard icons included in the framework that can be assigned to any button. To minimize the download size of the core icons, jQuery Mobile only includes these icons in white and automatically adds a semi-transparent black circle behind the icon to make sure it has good contrast on all background colors.
