Style Attribute - LiruJ/GuiCookie GitHub Wiki
A style attribute describes a certain aspect of a style. For example; the SliceFrame attribute allows an image to be specified along with some parameters, this is then used when drawing the element's frame to determine colour, image, slice sizes, and more.
Every style attribute has an optional Name parameter which allows for multiple of the same attribute type to be added to a single style. This is used when an element or component handles drawing multiple of the same attribute, rather than having separate elements.
