On this page, http://glidingholiday.co.uk/glidingholiday.htm , you'll notice that the background image for the h2 in the two columns on the right extend to touch the border of the divs class= .half.
Lower down the page on the left is a div called .imgBox250, which now has almost the same code as .half. The h2 has the very same css for both divs. But here the background image for the h2 doesn't reach the edges of the border, and is set further below the top border. It should also sit the same 5px below the top as in .half.
It's usually something obvious when I make mistakes, and I'm sure you guys will find it in minutes, but I've been fiddling with things for a while and am struggling.
