11.3.1 About Cascading Style Sheets

A Cascading Style Sheet (CSS) provides a way to control the style of a web page without changing its structure.

When used properly, a CSS separates visual attributes such as color, margins, and fonts from the structure of the HTML document. Oracle Application Express includes themes that contain templates that reference their own CSS. The style rules defined in each CSS for a particular theme also determine the way reports and regions display.

When using built-in themes, you can find the theme specific CSS files in the following locations:

/i/themes/theme_xx 
/i/themes/theme_xx/css

Theme specific image can be found in the following locations:

/i/themes/theme_xx  
/i/themes/theme_xx/images

Where xx is the theme number. Theme specific CSS files include the Oracle Application Express version number to preserve backward compatibility for imported applications using older versions of a theme.
