Reply To: Add search icon to mobile side menu

Most Welcome,

As you want to display the search form of 404 page as white and also the search form of mobile menu with grey icon. You can use the below css in Theme Setting >> Custom CSS >> GLobal CSS section:

/*Set search form on 404 page to white*/
.page-id-2503 .woodmart-search-form input[type=text] {
    border: 2px solid #ffffff;
}
.page-id-2503 .searchform .searchsubmit {
    border-left: 1px solid #ffffff!important;
    color:#ffffff;
}
