I want do something like that: I trying to ul first-child but no result. :(.

<ul>   
    <li></li> /* + :before */
    <li></li> /* + :before */
    <li>
        <ul>
            <li></li> /* remove :before or never create :before */
        </ul>
    </li> /* + :before */
    <li></li> /* + :before */
</ul>

please help.

:first-child just gets you the first child. If you want to remove :before from nested lis, set content: none for those lis:

ul li li:before {
    content: none;
}
