13. Themes 13  jQuery Mobile has a robust theme framework that supports up to 26 sets of toolbar, content and button colors.  Provides a consistent and touch-friendly look and feel for your widgets across platforms. It is built around the following essential concepts: 1. Swatch - one of several color schemes provided by your theme  uses single-letter designations  the default jQuery Mobile theme provides two swatches  "a" swatch is a neutral, gray swatch  "b" swatch has a darker color scheme designed to contrast with the "a" swatch. 2. Active State  The theme defines an "active" state  Gives immediate feedback upon a user action if there should be a brief processing delay  most mobile devices implement a 300ms delay between the time when the user lifts her finger from the touchscreen and the triggering of the "click" event  JQM adds the "active" state to a button whenever the device is poised to emit a "click" event so the user receives immediate feedback that the application is committed to processing the "click" in the next 300ms.

14. Themes (cont.) 14 3. Theme inheritance  You do not need to specify a swatch for everything  A swatch defined on the outermost container will be inherited by all the tags in the container  Can override swatch for portions of a container by specifying a theme swatch for one of its subcontainers  Can also build your own custom themes  Can also download and use 3 rd party themes  Note: Different releases of jQuery have different themes  1.1.1 is a very popular release

15. How to implement a theme 15  jQuery Mobile (v 1.4) provides two different style themes, "a" and "b" - each with different colors for buttons, bars, content blocks, and so on.  To customize the look of your application, use the data- theme attribute, and assign the attribute with a letter: 

16. data-theme = “a” 16  Black text on a light gray background for page content  Black text on a gray background for headers and footers  Black text on a light gray background for buttons  White text on a blue background for active buttons  Blue text on links  Light gray text (placeholder) or black text (value) on a white background for input fields

17. data-theme = “b” 17  White text on a dark gray background for page content  White text on a dark gray background for headers and footers  White text on a charcoal background for buttons  White text on a "cyan" blue background for active buttons  "Cyan" blue text on links  Gray text (placeholder) or white text (value) on a black background for input fields

18. Theming headers, footers, and popups 18  Use data-theme attribute

19. Theme Classes 19  two theme classes: a (gray) and b (black)  you can also create your own, custom class values  all the way up to the letter "z" ClassDesription ui-page-theme-(a-z)Specifies the color for pages ui-btn- (a-z)Specifies the color for a button ui-body-(a-z)Specifies the color for a content block, popups, lists etc. ui-bar- (a-z)Specifies the color for a bar (footers, headers, and other bars)
