WeCodeArt Framework utilities are generated with our utility API and can be used to modify or extend our default set of utility classes via PHP. Our utility API is based on a series of PHP maps and functions for generating families of classes with various options.
Utility classes can be used on any block under Advanced Tab -> Additional CSS Class(es) like in the screenshot below:
Q: Why use the utility classes?
A: Because their CSS is loaded only on demand (if utility class is added to block). In the end, you will create page designs with less/more optimized CSS.
