a {outline:none;}
Have you ever noticed a dotted line around a hyperlink on a live web site? Well, you can get rid of that ugly outline by setting one style for "a" (anchor).
a {outline: none;}
The css property= 'outline'
The Value='none'
a = is the selector used to target the anchor (the text used to create a hyperlink)
Designers typically include this or a similar style as a part of their CSS Reset.
