Alright so I know this code is kind of bad but here is a tutorial:
m.Execute(code_pieces<table>,target<GuiObject>) -> nil
Basically just put a string of CSS code bt only the selector and the code inside, such as #inner{} AND NOTHING ELSE!!! example:
{
"#inner{margin:5;}",
"#other_button{background-color:blue;}"
}
TO MAKE A GUI OBJECT BE SELECTED BY THE NAME THAT COMES AFTER THE #:
go into the object's properties and add a new attribute called "id" and name it the same id that you are selecting it with, such as inner or other_button.
currently supported colors:

currently supported instructions:
