When styling links (or any text which could eventually become a link) that could break into multiple lines, double-check your line-height. Not only for the sake of legibility, but to make sure a gap between two lines does not occur. Take a look at the following example I found on the web:
If your mouse hits the white gap between those two lines and you click, nothing happens. The user expectation is of course different: the user expects to land on a new page. This can be very frustrating and confusing for your users, but thankfully, a fix is very easy: adjust your line height (or even padding) and the problem is gone.
