Okay, this is going to sound really pedantic, but this is really annoying me. In default SharePoint there are a number of buttons. These buttons have text on them. When you roll you mouse over the button, the background and text changes colour. However, as the text does not have the same area as the whole button, the regions in which the hover occurs are different. For example, see the image below…
So, as you can see, the button turns oranges, and then the link turns black.
Now, this isn’t a problem in the default styles – the change from blue to black is very small. But you can’t guarantee that this is the case for rebranded sites – and of course, in mine it was a big difference.
Anyway, that’s what I did while tidying up my design.
