I'm new in Semantic-UI. In Foundation 6 to work with SASS you edit _settngs.scss to customize. What is the equivalent LESS file in Semantic-UI?

To make changes you need to alter any of the appropriate files in the following directory.
/semantic/src/site
For instance, we changed the global font size and color of red by altering
/semantic/src/site/globals/site.variables
and adding
@emSize: 16px;
@red: #F44336;
You'll have to rebuild your .less files obviously once you make the changes.
