Border overlapped by fields

To stop this from happening, go into the Designer

and

1. Click the CSS tab

2. Click any of the fields

At this point you will see a new empty rule appear in the work area of the CSS tab.

3. Insert the following declaration:

max-width: 90%;

so that the full rule becomes

.form-line {
 max-width: 90%;
}

Alternative Method:

Use the same rule in the form's injected CSS.
