Each visual element includes style properties that set the dimensions of the element and how the element is drawn on screen, such as backgroundColor or borderColor.
Style properties are either set in C# or from a style sheet. Style properties have their own data structure (IStyle interface).
UI Toolkit supports style sheets written in Unity Style Sheet (USS). USS files are text files inspired by Cascading Style Sheets (CSS) from HTML. USS syntax is the same as CSS syntax, but USS includes overrides and customizations to work better with Unity.
