I’ve made the changes, but stil there is some differences. On Firefox/Chrome is fine, but in IExplorer/Edge is not aligned.

I did a research in order to fix IE only, and I applied these rules in CSS:

_:-ms-lang(x), .sh-nav li.menu-item { padding: 0 76.6px 0 0; } /* for IE11 / IE 10 */

_:-webkit-full-screen, .sh-nav li.menu-item { padding: 0 76.6px 0 0; } /* for Edge */
