Remove the underline of tag

<A> label pseudo-class style

A set of specialized pre-defined classes are called pseudo classes, which are mainly used to process the hyperlink status. The hyperlink text status can be controlled by pseudo-class selector + style rules. Pseudo-class delimiters include:
Total: A indicates connections in all states, such as a {color: Red}
① A: Link: unaccessed link, for example, a: link {color: Blue}
② A: visited: The accessed link, for example, a: visited {color: Blue}
③ A: active: the link color when the link gets the focus, for example, a: Active {color: Blue}
④ A: hover: When you move the mouse over the link, for example, a: hover {color: Blue}
Generally, the status of a: hover and A: visited links (color, underline, etc.) should be the same.
The first three attributes correspond to the link, vlink, and alink attributes of the Body element.
The procedure of the four States is as follows: A: Link-> A: hover-> A: Active-> A: visited. In addition, a: Active cannot be set with or without underscores (always ).

1. <Style type = "text/CSS">
2. <! --
3. A {font-size: 16px}
4. A: link {color: Blue; text-Decoration: none;} // unaccessed: blue, underline-free
5. A: active: {color: red;} // activation: red
6. A: visited {color: Purple; text-Decoration: none;} // accessed: Purple, no underline
7. A: hover {color: red; text-Decoration: underline;} // move the cursor near: red or underline

How to remove the underline of <A>:
Use the code "text-decoration" to set the hyperlink underline"
Syntax:
Text-Decoration: None | underline | blink | overline | Line-through

Text-decoration parameters:
None: No Decoration
Blink: flashing
Underline: underline
Line-through
Overline: dashes

To remove the underline, set text-decoration to none.
For example, <style> A {text-Decoration: None} </style>
Can be used on this basis: for example: <style>. myclass A {text-Decoration: None} </style>
<Style> Div A {text-Decoration: None} </style>

Can be extended to the label pseudo class:
A: link {text-Decoration: none; cursor: pointer; color: red ;}
A: visited {text-Decoration: overline; cursor: pointer}
A: active {text-Decoration: overline; cursor: pointer}
A: hover {text-Decoration: overline; cursor: pointer}
. Myclass: hover {text-Decoration: overline; cursor: pointer}
