At this point the majority of the underlying "functionality" for your Article content type and the Views that will display the Article listings/teasers are now complete. However, it's very unlikely that things are "looking" the way you want them to quite yet. That's where Theming comes into the picture (customizing the "look and feel" of your site). First you'll learn how to customize the theme of the full Article pages (nodes), and then how to theme the Articles: Page and Articles: Block Displays from Views module. You will learn how to gain complete control over the HTML and CSS of every field of information, allowing you to customize them in any way you'd like.
