An Introduction to Themes

In the Vahana cloud, the “Theme” is an advanced module. You can access it by clicking the VDLC icon in the top panel of the Vahana cloud portal. It allows you to design a visual pattern or a collection of visual patterns. These visual patterns impart a distinct look and feel to the application pages and UI (user interface) items in the page layout. Designing software applications with organized themes not only makes the application aesthetically interactive and beautiful but also increases its commercial viability in the marketplace.

When you create a theme, you find the following sub modules or sections:

Sub Modules	Description
Color	It provides multiple in-built color categories. In these color categories, you can use a color configurator to define a color and the color tone under the selected color. Apart from predefined categories, you can create a custom category with a desired color and color tone. You can use the color category to impart the background color to layouts and elements.
Typography	It also has multiple predefined categories of typography styles. A category of typography includes the style name, font family, italic, size, line height, line spacing, and font weight.
