This is a paragraph with a test link in the middle, having 2em horizontal margins and yellow background-color. The margins are clickable in IE6-7, they are not clickable in any other browsers. Then there is a second test link without margins, but inside a span having the 2em horizontal margins. The margins are not clickable in IE6-7, but the right one incorrectly gets the link background color (unless it wraps on multiple lines). Then there is a third test link like the second one inside a span with margins, but with some white space between the closing tags of the link and the span. No more background extension on the right margin in IE6-7. A fourth test link is like the third one, but with some white space also between the opening tags of the link and the span, like the third one it has no problems in IE6-7. Finally a fifth link with display: inline-block and margins. No problems in IE6-7 (but of course it doesn't wrap in the same way as an inline one).
