iotaCSS allows you to fully customize all classes based on your needs. Assuming you would like to change the syntax of
the classes from .u-absolute to u-position-absolute. To do this, you should update the namespace classes:
Enable responsive position utilities
By enabling the responsive position utilities, you have access to a set of utility classes which bind to breakpoints. By
default, they bind to the iotaCSS global breakpoints specified in Settings.Core.
Heading positioned absolute on mobile and fixed on tablets and up.
Set breakpoints only for position utility
In case you would like to use different breakpoints to position utility only, you should use the local variable.
