Hello,

You can easy add custom css code here: http://prntscr.com/gbgjxt

@media only screen and (min-width:993px) {
    header.de_header_2 {height: auto;}
    header div#logo {height: auto;}
    header div#logo a img {max-width: 260px;max-height: 110px;}
}

1, you need using a child-theme to custom css code for your website.

2, Please don't change theme name from "archi" to "bodrummobilya".

Thank you
