Hi James!
I dug into the css on the other plugin and I think this should do the trick: `.icon-shopping-cart {
background-image: none;
background-position: none;
background-repeat: no-repeat;
background-position: none;
display: inline-block;
height: auto;
line-height: inherit;
vertical-align: inherit;
width: auto;
}`
I wouldn't worry too much about those flags. The "My Shortcodes" plugin is already using that method, so it probably won't have too much of an impact, but do try the updated code as it should be more efficient. Please let me know what you find. Also, thanks for the review. Much appreciated!
