[OpenLayers-Users] Another offset problem (follow-up on Bug? Zoom box offset when using large scales)

Sun Aug 26 20:16:22 EDT 2007

Dito here. But only notice the problem on IE6. IE7, FF and Safari dont seem
affected. Basically the mouse pointer coordinates (using MousePosition) are
offset by the size of the margin. Removing the margin-left off the main
content div (which contains the map) stops the offset, (but of course breaks
the template!)

Heres the map:
http://www.geograph.org.uk/mapper/

removing

	margin:4px 10px 0px 170px;

from ".content2" in the css file fixes it.

Related:

Also having (had) a 10px border on the map div did also offset the
coordinates, but changing that to a background colour and 10px padding
sorted that. (cant remember which browsers but at least Firefox)

Do get the two pixel offset too in Safari and FF, that could be related to
the ticket. (hmm, could that be the 2px border on the content2 class? ....
Yes Confirmed removing the border removes that small offset; at least on
Firefox (as has easy CSS editing) ... so thats not going to be so easy to
fix...)

Cheers,

Barry
