By learning how to use HTML, you will be able to create websites that are both aesthetically pleasing and functional.

CSS: Styling Your Website

As a front end developer, it's important to have a strong understanding of CSS. CSS is responsible for the styling and look of your website. Without CSS, your website would be a bland, unorganized mess.

CSS is a style sheet language that is used to style HTML documents. It can be used to style the document's layout, colors, and fonts. CSS is also used to style other web-based documents such as XML and SVG.
