Using Classes

RoCSS utilizes Roblox's CollectionService to obtain a table of GUI elements it should apply certain styles to.

Tagging Elements

To let RoCSS know that it should apply a style to a certain GUI element, we have to add a Tag to the object. To add a tag to an instance, scroll down in the Properties window until you see the Tags section. Then, click on the + icon to add a tag to it. This tag should be the name of the class you wish the element to be a part of.
