Answer 1

You could take the classes for the UL elements plus the Header tag (h3) and reset the browsers default margin and padding properties to your settings.

.vertical-menu-list, .vertical-menu-link, h3{
    margin: 5px;
    padding:5px;
}

Or target the elements themselves.

ul, h3{
    margin: 5px;
    padding:5px;
}

This all depends on there being no other margin or padding styles on the other elements in between.
