Ext.js - Style


Advertisements


Application Styling refers to user adjustment of the look and feel of the components. These adjustments may include: color, color gradients, font, margins/padding, etc. Ext JS 6 has a new way of styling the application.

It uses SCSS for styling. SCSS is a more dynamic way of writing the CSS code. We can write the variables in our stylesheet with the help of this. However, a browser cannot understand SCSS. It can only understand CSS, hence all SCSS files should get compiled into CSS to a production-ready code.

Thus, SCSS file is called preprocessor files. In Ext.js, compilation is done through Sencha CMD tool. Sencha CMD compiles it manually only once using the following command.

sencha app build [development]

Global_CSS is the main CSS file, which has all SCSS variables associated with it in ExtJS that can be used in our application for customizing our theme by providing different value based on our need.

Following are some of the CSS variables available in the Global_CSS in Ext.js.
