I am making a form using text input fields and selectboxes. Each input is in another form td. I have a problem with the borders of the input fields. Unlike other browsers, Firefox default puts the border inset. By declaring the doctype this problem normally is solved (I use:
<!DOCTYPE html>). Anyhow, it won’t with selectboxes. Other browsers have no problem with it.

<select>has border-box sizing by default in all browsers. So if you’re setting explicit sizes, you’ll see the above behavior. You can use-moz-box-sizing: content-box; box-sizing: content-boxto override the default.
