A while ago I wrote this article about transparency in internet explorer 6. This was just one of many problems with browser compatibility that can hit you when you design a Joomla template. This article is about another such problem: the so called 'double margin bug of internet explorer'. If you see that your Joomla site looks good in Firefox or the brand new Google Chrome browser, but in internet explorer you see that some parts are not at the right place, like there is a double margin, then you've come accross this bug.
