3.6 Universal Theme Design System

Applications you build with Oracle APEX use a built-in design system called Universal Theme.

Technically speaking, Universal Theme consists of HTML templates, Cascading Style Sheets rules, icons, images, and JavaScript libraries. However, APEX shields you from having to understand these technologies. It's only important to remember that these resources cooperate to automatically ensure a consistent, professional look to all the pages you create on any desktop or mobile screen size.

• Theme Styles
  Universal Theme comes with several pre-defined styles.

• The Role HTML and CSS Play to Format Data
  While Universal Theme lets you deliver great results without being an expert in web technologies, understanding the role HTML and CSS play is useful when customizing data formatting.
