HTML (Hyper-Text Markup Language) is a standardized system for tagging text files to achieve font, color, graphic, and hyperlink effects on World Wide Web pages. In other words, it is a computer language that allows you to tell the computer what to display and how to display it.

 

CSS (Cascading Style Sheet) is the language for describing the presentation of Web pages, including colors, layout, and fonts. It allows one to adapt the presentation to different types of devices, such as large screens, small screens, or printers. It is a reference sheet that works inside an HTML document, it dictates how the information in the HTML document is to be displayed.

 

Within the CSS document there are specific the exact characters are needed to display the HTML how you want, otherwise the computer will not be able to read it. It is important to have an understanding of CSS rather than copying and pasting, as even one extra bracket can change the look of the whole page. It is helpful to be able to find your errors.
