Ajaxcart Pop-up error message instead of block message

[Webmaster001]

We have a custom ajaxcart order form. We want to know if it is possible that we alter the style.css somehow that if there is an error message instead of showing the message inline (as block) it pops up so it won't move other input fields we customized.

 

Right now, when the error messages shows up it partially gets covered by other input fields and makes the cart look messed up.
