If your site utilizes CSS then it is a simple matter to add it to your menu or a footer.
The card above is made using an SU set, One of a Kind (my sister's stamp set). I stamped the bottom on Groovy Guava, using Groovy Guava ink and an SU wheel, It's Beautiful. I also used Chocolate Chip ink, paper, and grosgrain ribbon, and Purely Pomegranate ink & paper.
Edited to fix a link that didn't work. Sorry to anyone that tried to follow that broken link.
