I set this CSS code that i found in other subject in the costum.css file but it is not working to increase – to decrease it works.
.header-type-3 .logo-with-menu { width: 300px;}
.header-type-3 .main-nav .menu {width: 870px;}
When I use the browser inspector the custom css code is there and I can set for example 50px and it goes smaller but if I set 600 it keeps the size, it does not go any bigger.
