CSS TEXT C SS has several options for defining the styles of text. The reason is that you'd be assigning the same font face to all your styles, for example, while you'd want different font weights and sizes for headers and content areas etc.
Uppercase forces all letters to uppercase.
Lowercase forces all letters to lowercase. The official CSS standard provided by W3C also includes properties for word spacing, letter spacing and vertical align, but these aren't supported by todays browsers. T he color is not part of the font collection in CSS - rather it has its own definition.
