[Maypole] width of edit fields

[Dave Howorth]

The field boxes on the edit page are fairly narrow and don't make much 
sense with long text fields such as my sequences. I've tried to change 
them, but I'm a css ignoramus and can't make it work. I've found 
explicit width settings for text inputs and textareas:

input[type=text] {
     height: 16px;
     width: 136px;

and

textarea {
     width: 136px;

These settings seem to be shared between the search, addnew and edit 
boxes. I think what I want is for the boxes to be as wide as the space 
available, so I tried commenting out the width lines. This caused the 
boxes to get a little bit wider, but not full width (and not the same 
width as each other?). I tried an explicit large value and that forced 
the boxes to become wide, but it isn't what I want to do.

What is it that limits the width of these boxes?

Thanks, Dave
