Remove a piece of blue


I’m currently coding a newsletter form.

My page :

I would like remove this little piece of blue here :

To have that one :

How I can do that ??

Thank you !

That blue doesn’t show up in Firefox. What browser are you seeing it in?

EDIT: O, I see what you mean. You could try

border-top: 0;

But I’m using an old version of Firefox right now (3.6) and the arrow appears down from and way to the left of the submit button, which is why I didn’t see it. You need to fix its placement.

I’m using Firefox 8 (last version).

It’s ok with “border-top” !

thank you !!!
