Customize Menubar and Mobile Menu

1. Use:

#menu ul li a {
  border-right: none;
}

2. Use:

#menu .current-menu-item a, #menu .current_page_item a {
  background: #fff;
  color: #f5b7c3;
}

3. Use:

#header {
  padding-bottom: 0;
}

4. Use:

h1 {
  color: #000;
}

5. Use:

h2 {
  color: #f5b7c3;
}

Note – Remember to remove the spans.

6. Looks like you’ve already simplified your menu, however a design update is coming soon that will improve the mobile menu. You might try a plugin like http://wordpress.org/plugins/mobile-menu/ in the meantime.
