1. Basic selector (single)

Universal selector (*): will match all HTML elements

Tag selector: corresponds to all HTML tags, with the same name as the tag name.

Class selector: you can add styles by defining the same class attribute for a class of HTML elements. Class styles are defined with "." The beginning definition. The CLASS property of CSS generally uses tables for cascading styles. For example:

.news indicates that the element of class=news adds style

News indicates that the element of class=news adds style.

.news title represents the elements of class=title under class=news

ID selector: adds styling to HTML elements that mark specific ID attributes. \

Definition of Id selector, starting with the "#" sign

A web page cannot have the same value of ID. ID is unique like an ID number.

The ID attribute of the HTML element, which is generally used by JavaScript

2. Combination selector

Multi-element selector: that is to define multiple HTML elements at the same time.

Body,p,a,ul,li,p {margin:0px;padding:0px;}

Each HTML element has a default style.

Descendant element selector: separate selectors with spaces.

.news .title p {background-color:#FF0000;}

Child element selector: use the > sign to separate the parent-child selector, there is no third-level problem.

Third, pseudo-class selector

Pseudo-class selectors generally add styling to hyperlinks.

Hyperlinks have four states:

Normal status a:link {}

Put the status a:hover {}

Activation status a:active {}

Visited status a:visited {}

Global link

A:link,a:visited {color:#333;text-decoration:none;}

A:hover {color:#FF0000,text-decoration:underline;}

Add class styles to links (class= "a2")

A.a2:link,a.a2:visited {}

A.a2:hover {}
