Where to edit checkout layout?

The address boxes in the checkout are too wide for the content area, and the shipping address extends into the right-hand column (see attached screenshot). Please can anyone tell me where to edit this?

Thank you.

Hi SarahW,

To edit the width of the address boxes go in HikaShop > System > Configuration > Display.

Click on the edit "icon" next to Front-End CSS File.

Then edit the properties of:

.hikashop_checkout_address{
	width: 250px;
}
.hikashop_checkout_address_right_part{
	width: 250px;
}

Thank you very much for that, Xavier .
