Through css you can customize any links you have on your blog pretty much any way you want them to look. If you want a rundown on link styling than check out W3schools.
In your custom.ss file add the following code. You can put it anywhere you want but I recommend putting it at the top.

Always describe what you’re doing by putting your descripton between the comment tags /* */ at the beginning shown below in green. The comments aren’t shown on your rendered page and it just makes things easier for you to remember…
/*link styles*/
.custom a {put your custom styles here for links;}
.custom a:visited {put your custom styles for links that have already been clicked on ;}
.custom a:hover {put your custom styles for when you hover over a link without clicking on it ;}
The above does a sitewide link customization. If you want to just target links in a post or page then check out this tutorial
