Basic HTML

HTML is the language that web browsers and web servers use to display web pages. HTML “tags,” when added to a plain text document, instruct web browsers how to display that content on a web page. If a web page is a house, its HTML code is its blueprint. 

CSS: Cascading Style Sheets

Cascading Style Sheets — even the name sounds a little intimidating, like perhaps you’re falling down a steep slope.  But the name is just an accurate description of what CSS is — "sheets" (pages or chunks) of code that describe the style of a document in such a way that multiple commands "cascade" — in other words, they’re applied in a certain order that ensures that both the user and the page designer get as close to the same effect as they possibly can.

Creating Forms

If you want to give your readers the ability to interact with your site – to send information to it rather than simply receive information from it – you’ll need to move beyond basic HTML. Forms are used to gather data from your users. When you use a search engine or enter a login name and password, you’ve seen a form in action.
