Q&A: Extra whitespace in lists

Q: I keep having problems with a list showing up as two lines of instead of one (there is a big gap between the items) in Internet Explorer 6. I don’t know what is causing it as there is nothing inside the list items but text.

A: The problem is that you most likely have line breaks and tabs in between the closing LI and the next opening LI. This is a great thing to do to keep your code readable but Internet Explorer 6 (MSIE6) has a problem with it. One workaround would be to add the linebreaks and tabs inside the brackets of the LI elements, but that is neither pretty nor clever as MSIE6 is on the decline. You can use CSS to work around the same problem by using a fixed height for MSIE6 and overriding this for newer and better browsers that understand the child selector. A sequence like li{height:1em;} html>body li{height:auto;} will fix your problem as MSIE6 also increases the size of the element when the font is larger or the content of the list item spills out into two lines. Without the second selector newer browsers would cut off your content.
