What does it mean to encapsulate rules?

Question

Layout

The client requested to use the https://simplegrid.io grid and said to encapsulate the rules so that there are no conflicts with the current layout. Tell me how to encapsulate the rules correctly?

Answer 1

You need to take the grid file https://github.com/zachacole/Simple-Grid/blob/mast...
Remove common classes and tags from there, leave only the grid.
Add some prefix to all grid classes (container, row, col). For example sg-.
Compile file.
