If you use Link back
This is only for the links that you want to change for this kind:
How ever you can do it any how you want to but this is how i have learned and wanted to share how i do it.
Text-decoration you can use:
text-decoration: underline overline dotted red;
text-decoration: underline wavy blue 5px;
text-decoration: underline overline;
letter-spacing: is if you want to space out your letters to look different. The only way to use it, is to mess with the numbers and that way you get an idea of what the numbers do when you go from -1 to just 1 or 2. be creative.
Margin and padding are how u want each words to be moved apart. mess around with it and you will get the idea of it.
for the hover you can really use a back background if you want, might look funky and now how you want it this is just going to work for all your main links that don't have anything special to them.. just simple links.
If this has helped you in anyway, link back!
