Answer 1

Inside your selector use the :not(:first-child) pseudo-class on the ancestor li to exclude the first <li> in a list from matching the selector - even though the style-rule ultimately affects only div.rpwwt-post-excerpt elements.

Like so:

li:not(:first-child) div.rpwwt-post-excerpt {
    display: none;
}

Answer 2

Just select li is not first-child.

use :not for is not , and use first-child to select first element.

so , ul li:not(:first-child) { display:none; }
