Ext.js - Style

Application Styling refers to user adjustment of the look and feel of 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 the more dynamic way of writing CSS code.
We can write the variables in our style sheet with the help of this. But a browser cannot understand SCSS it can only understand CSS, so all the SCSS file should get compiled into CSS to a production ready code.
That why SCSS file is called preprocessor files. In Extjs compilation is done through Sencha CMD tool.
Sencha CMD compiles it manually only once using command as below:
sencha app build [development]
Global_CSS is the main CSS file which has all SCSS variable associted with it in ExtJS which we can use in our application for customizing our theme by providing different value based on our need.
