Hi mate the HTML tags are styled mostly by your theme, so you'll have to write some custom CSS to make it look different.

strange as nothing else in my theme has boxes!  OK will have a think on this one.

What about the width of fields ?

If you use Chrome Developer tools (F12) and select an element on the page you can see where it is inheriting it's style from. If you give me a link here I can take a quick look for you and point you in the right direction.

no I can't shift the box - can you provide me some css to do this please?

This is the page:

The box is horrid as is the spacing in it, needs line breaks, and the field width is too narrow.

i am not a coder but if you can give me the css (if you don't mind!) I know where to put it in my theme.  I would be most grateful.  Thank you.
