Hyper Text Markup Language (HTML) is the markup language that makes up websites. HTML makes up the text, images, links, and basic functions of every website. HTML is used in every website no matter how big or small.
HTML tags are used to help format websites and use special names that are encoded within HTML. There are many tags that are used to format websites such as: < header> header> , < nav> nav>, < body> body>, and < footer> footer>. These kinds of tags are used to group similar content together or help organize code for the developers. For example, the < nav> tag which is often used to hold the links for the other parts of the website (a nav is often found in the top right corner of a website).

CSS is the language which decorates the HTML. It decorates it sby changing: colours, font settings, size settings, backgrounds, and white space. CSS is a necessity with HTML, because without you are left with an ugly, un-styled website.
