@creedon Hi, yeah i had changed that value to get the navigation in line with 'studio' in the logo.
Originally I had changed the top value in the split navigation code to achieve this but thought i'd try with the line hight in the site navigations instead to see if it helped with the issues i had. Have reverted back to using the top value in the below code to achieve it. Both seem to make no difference to helping with the issues.
/*Make split navigation*/
.header-nav {
position: absolute;
top: 130px;
bottom: 0;
margin-top: 0!important;
}
.header-nav-item:nth-of-type(2) {
margin-right: 345px!important;
}
