Paul,
As always you end up delivering the answer I can never seem to find.
Thank you very much!
However, I had to modify and deal with the Sign In link, which you might want to update in that documentation.
@media screen and (max-width: 1113px) {
#sp-header #offcanvas-toggler.offcanvas, #sp-header #offcanvas-toggler.mega
{display: block !important;}
.sp-megamenu-parent.d-none.d-lg-block
{ display: none !important; }
.sp-sign-in { display: none !important; }
#offcanvas-toggler {
display: inline-flex;
align-items: center;
height: 3rem;
line-height: 8rem;
font-size: 20px;
}
}
