For the Flash:
object {outline:none;}
For links:
a {outline:none;}
There you have it 
P.S. The dotted outline is created to help those who cannot use a mouse to navigate, but keyboards. The outline is a visual indicator to navigate around. If you are working on a website that needs high accessibility, you might not want to hide the outline.
Sometimes we need to do an inline CSS for whatever reasons. Very quick easy way to create a hover effect:
<a onmouseover=”this.style.color=’#944e06′;” onmouseout=”this.style.color=’#cb6412′;” style=”color:#cb6412; text-decoration: underline;” href=”http://www.nikkifoundation.com/about”>Check it out.</a>
Additional styling:
this.style.fontWeight=’bold’
this.style.fontStyle=’italic’
this.style.background=’white’
Good Luck!
