The definition of CSS consists of three parts: selector (selector), properties (attribute) and value (attribute).

The basic format is as follows:

Selector {property:value} that is: (selector {attribute: value})

The definition of CSS has the following requirements:

(1) attributes and values should be separated by colons. Such as body {color:blue}. The selector body refers to the main part of the page, color is the attribute that controls the color of the text, and black defines the value of the color. The effect of this example is to make the text on the page blue.

(2) if the value of an attribute consists of multiple words, you must put quotation marks on the value. For example: P {font-family: "sansserif"}. This example defines the paragraph font as sansserif, and the name of the font consists of two words, so put it in quotation marks.

(3) if you need to specify multiple attributes to a selector, you can use a semicolon to separate all attributes from values. For example: P {text-align:center;color:red}. This example defines the arrangement in a paragraph play, and the text in the paragraph is red.

(4) in order to make the defined stylesheet easy to read, the definition of the stylesheet is best written in a branch format. Such as:

{

Text-align:center

Color:black

Font-family:arial

}

In this example, the Chinese character of the paragraph is black and the font type is arial.
