Hi Dmitrii,
Here’s a CSS you may try adding through Appearance > Customize > Additional CSS:
@media (min-width: 1025px) {
/* CSS in here for desktop only */
.navigation-search.nav-search-active {
left: unset;
max-width: 95%;
}
span.menu-bar-item.search-item.active.close-search {
border: solid 1px rgb(174, 174, 174);
border-left: none;
}
}
.inside-navigation input.search-field {
color: rgb(0,0,0);
}
You may modify the values to your preference.
Hope this helps!
