Cascading Style Sheets are to web development as interior design is to a home: they determine the layout and presentation of your pages. Just like a house, a web page needs a solid, stable foundation, walls, and the ability to meet building codes before design choices should be considered. In HTML, that’s content, structure and validation. For basic web pages, everything else is CSS.
