A great easy improvement for any website is getting rid of that annoying dashed box that appears when clicking on a link. Many big sites like eBay.com and Google.com have not removed this dashed box from their hyperlinks and I think it just looks tacky. I understand that it might help some users understand that it is a link, but it also detracts from the design of the page. I think we have surpassed the age of tables and outlines, people know from common sense today where a link is and isn’t.
Here is a small snippet of CSS that you can add to your stylesheet that will remove the outlines [dashed box] from your hyperlinks. This is successful in Mozilla Firefox 2, 3, Internet Explorer 7, 8, and Safari 3, 4.
I think it is an easy way to add some class to your page. I implement this in every page I design. Below is an example of a dashed/outlined hyperlink box.
