How do I make a containing div overflow hidden inside it's containing div-CodePudding

I'm trying to give this simple calculator app I'm making a 'light sheen', like what you'd see on a phone screen under light. What I've done is I've put a div for the light sheen inside the containing div which is the phone shape, but I can't make it so overflow is hidden for the light sheen div.

Hopefully the current code snippets help:

<div >
        <div ></div>
        <div >

.phone-container {
    height: 750px;
    width: 400px;
    background: rgb(0, 0, 0);
    border-radius: 60px;
    border: 5px solid rgb(172, 172, 172);
    display: flex;
    flex-direction: column;
    justify-content: space-between;
    align-items: center;
    padding: 20px;
    padding-bottom: 50px;
    overflow: hidden;
}

.light-sheen {
    width: 900px;
    height: 450px;
    background-color: white;
    position: absolute;
    bottom: 0px;
    transform: rotateZ(-35deg);
    opacity: 0.1;
}

Any help is appreciated, thanks!

CodePudding user response：

Since you use position: absolute; on light-sheen, it's not possible to hide the overflow part.

Make light-sheen position: relative; instead.

.light-sheen {
    width: 900px;
    height: 450px;
    background-color: white;
    position: relative;
    bottom: 0px;
    transform: rotateZ(-35deg);
    opacity: 0.1;
}
