This section is for more advanced HTML topics than the HTML Basics section. Inserting more complicated, heavier types of content into your pages, optimization, and making your markup work better with stylesheets are all on offer here.
|Tables||Tables are grids of boxes used for displaying data. In HTML, they're represented by long nests of tags.|
|IDs and Classes||IDs and classes are two ways of naming sections of your page to enable referencing them in links, scripts, and stylesheets.|
|Audio and Video||HTML5 now includes built-in tags for displaying audio and video content without using a plugin. You just have to encode your media in the right formats.|
|Meta and OpenGraph||Meta tags and OpenGraph tags allow web apps and search engines to better read and understand your page's content.|
