What is CSS

CSS (Cascading Style Sheets) is a language for specifying how documents (HTML, SVG OR XML) are presented to users. Mainly how they are styled and laid out.
Some exmple of basic styling that can be done on CSS are, changing the size and color of headings and links. turning a single column of text into a layout. it can be used fo effects such as animation.

CSS Syntax

CSS is a rule-based language — you define the rules by specifying groups of styles that should be applied to particular elements or groups of elements on your web page.
For example, you can decide to have the main heading on your page to be shown as large red text. The following code shows a very simple CSS rule that would achieve the styling described above:

In the above example, the CSS rule opens with a selector . This selects the HTML element that we are going to style. In this case, we are styling level one headings (<h1>).
We then have a set of curly braces { }.
Inside the braces will be one or more declarations, which take the form of property and value pairs. We specify the property (color in the above example) before the colon, and we specify the value of the property after the colon (red in this example).
This example contains two declarations, one for color and the other for font-size. Each pair specifies a property of the element(s) we are selecting (<h1> in this case), then a value that we’d like to give the property.
