Hi

how to expand the fields ?

Hi,

You can do that in css, use something like FireBug to see which class is to edit, and then add the css property in the Frontend css File in HikaSHop > Configuration > Display.

I can't find correct line in CSS to change dimensions .....

Hi,

Here is some documentation on how to do that:

If you still can't solve your problem, give us your website url.

laptop-zona.net this the site I working with css, byt i can't find true line in that front-end css and correct them...

Try this property:

.hikashop_checkout_login_right_part{
    width: 99% !important;
}
