📖 Rule Details

This rule aims to enforce a number of attributes per line in templates. It checks all the elements in a template and verifies that the number of attributes per line does not exceed the defined maximum. An attribute is considered to be in a new line when there is a line break between two attributes.

There is a configurable number of attributes that are acceptable in one-line case (default 1), as well as how many attributes are acceptable per line in multi-line case (default 1).
