CSS body:

1. CSS, the full name of cascading style sheets, is a computer language used to express file styles such as HTML or XML.

2. The stylesheet defines how to display HTML elements, just as color attributes do. Styles are usually saved in an external .css file.

3. Which style will be used when the same HTML element is defined by more than one style?

In general, all styles are cascaded in a new virtual stylesheet according to the following rules, where the number @ 4 has the highest priority.

@ 1, browser default settings

@ 2. External style sheet

@ 3. Internal stylesheet (located inside the tag)

@ 4. Inline style (inside the HTML element)

4. There are two locations for the stylesheet, the first is in the tag in the header, and the second is to reference the external file in a separate css file by using the tag within the tag.

@ element selector p {color:red;}

Element selector

@ ID selector # id {color:red;}

ID selector

@ Class Selector .className {color:red;}

Class selector

@ derived selector div p {color:red;}
