black text

Hi,
I edit Wikipedia regularly and I want dark mode so it is easer on my eyes. There is no skin which does this for you there are chrome extension which do it but I find them hard to use and they also slow down my computer. You can add custom css to a skin so I added this to a skin:

body {background-color: rgb(24, 24, 24);}
.cnotice {
    position: relative;
    overflow: hidden;
    background: #f8f9fa;
    border: 1px solid #a2a9b1;
    border-radius: 2px;
    margin-bottom: 1em;
    cursor: pointer;
    color: #222;
    font-weight: 500;
}

It worked but only on the side and bottom does anyone know a fix?
