Hey, they’re empty — the markup is irrelevant. The only reason I didn’t just use pseudo-elements is so this would work in IE7 and older. <b> and <i> were quick

Hey, they’re empty — the markup is irrelevant. The only reason I didn’t just use pseudo-elements is so this would work in IE7 and older. <b> and <i> were quick and easy to type. I would not recommend copy and pasting any of the code on the page, just the technique, if a scalable, fast-loading arrow is desired :)
