Im sorry if this seems like a stupid question but I am still learning php.
I need to limit the width of a form that is to go in a side column on a web page. The column width is only 175px so when I insert the form, the fields extend outside of the margins.

What do I need to change in the php for the form to limit this from happening?

To add a bit of complexity. I will also be using another form in the main content of another page so I cant restrict the width of all forms. Just this one.

Thanks in advance to anyone who can help.
