CSS – Web Development Skills – Free Udemy Courses

If HTML is our body then CSS is clothes. Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language.

HTML and CSS are the two most important languages for a new web developer to learn. They are also the easiest.

CSS has a simple syntax and uses several English keywords to specify the names of various style properties.

A style sheet consists of a list of rules. Each rule or rule set consists of one or more selectors and a declaration block.

Before CSS, nearly all presentational attributes of HTML documents were contained within the HTML markup. All font colors, background styles, element alignments, borders, and sizes had to be explicitly described, often repeatedly, within the HTML. CSS lets authors move much of that information to another file, the style sheet, resulting in considerably simpler HTML.

For example, headings (h1 elements), sub-headings (h2), sub-sub-headings (h3), etc., are defined structurally using HTML. In print and on the screen, the choice of font, size, color, and emphasis for these elements is presentational.
