I'm trying to style a button that allows the reader to click it, then be brought to the single post page to continue reading the article. I'm trying to set it up using this tutorial: http://www.oscaralexander.com/tutorials/how-to-make-sexy-buttons-with-css.html. However, it's not working. The link and text shows up, but the actual background image of the button does not work. Any ideas? Thanks.
