CSS Background Color of ::before element not showing-CodePudding

I'm following some tutorials to do some coding, and I've found that for some reason, when i use the ::before pseudo attribute, and try to set the background color of it, nothing is visible.

body {
    display: flex;
    justify-content: center;
    align-items: center;
    min-height: 100vh;
    background: #1d061a;
    font-family: consolas;
}

.container {
    display: flex;
    justify-content: center;
    align-items: center;
    flex-wrap: wrap;
    padding: 40px 0;
}

.container .box {
    position: relative;
    width: 320px;
    height: 400px;
    display: flex;
    justify-content: center;
    align-items: center;
    margin: 40px 30px;
    transition: 0.5s;
}

.container .box::before {
    content: '';
    position: absolute;
    top: 0;
    left: 50px;
    width: 50%;
    height: 100%
    background: #fff;
    border-radius: 8px;
    transform: skewX(15deg);
    transition: 0.5s;
}

(I couldn't figure out how to get the code to display correctly)

You've got some error in your ::before missing a ; after height declaration.

Little syntax error; all that was missing was a " ; " after your height declaration in the ::before selector, causing your background-color to not be picked up.

    display: flex;
