How To Select Li Child Of A Ul Without Nth-child Via Css?

I am getting a problem with my project where our client has used a logo image inside the menu's ul li. He has used a class with li where the logo is placed but I cant use the class

Solution 1:

:empty selector should be what you are looking for.

ul li a:empty {
    background:red;
    width:50px;
    display: inline-block;
    height: 10px;
}
