To customize the look of a Sharepoint site you can achieve a lot by making a CSS which overrides the standard CSS (on that subject more later). To determine what part of the standard stylesheet I have to override the IE Developer Toolbar is an absolute must have.
However when installing in Internet Explorer 7 it didn’t show me the DOM tree in the left screen. This worked flawless in Internet Explorer 6 so I was a bit surprised about the empty screen.
I looked around on the internet and though the solution is out there I didn’t see a clear answer. So this is a reminder for myself and hopefully for more people out there looking for the solution. To enable the DOM tree you need to ‘Enable’ the option
Script ActivX controls marked safe for scripting. This can be found in
Tools > Internet Options > Security Tab > Custom level....
Here you have to scroll down a bit and then you can put
Script ActivX controls marked safe for scripting to enable and after you do a restart of Internet Explorer the IE Developer Toolbar should be fully functional.
