html - change default hyperlink properties in custom tag -

I have found the following .. How do I change the properties of the hyperlink text in blue in this example and underline black And not underlined?

At very basic level, like this:

  a: Link {color: black; Text-decoration: None; }   
 To make it specific to the link within your custom tag (including  display: block  to spread its code in the width of its container ):  
  ab.sa:link {color: # 000; Display area; Text-decoration: None; }   
 and to change the hover style:  
  ab.s a: hover {background-color: # 000; Color: #fff; }   
 If you want more information, then there is a tutorial on it that tells different pseudo squares.
