Placing child above and outside overflow parent-CodePudding

in the following code example, I'd like to place my circle outside the red div and still be seen. however due to parent's overflow: auto it is not fully seen, even when I change overflow-x to visible and overflow-y to auto, it is still hidden. adding the code example and the outcome.

Removing overflow: auto from .child fixes that:

.parent {
    background-color: blue;
    height: 100px;
    width: 100px;
    padding: 20px;
}

.child {
    position: relative;
    background-color: red;
    height: 50px;
    width: 50px;
    padding: 10px;
    /* overflow: auto; */
    
}

.circle {
    position: absolute;
    background-color: green;
    left: -5px;
    border-radius: 50%;
    height: 20px;
    width: 20px;
    background-color: green;
}

you can try this

// Removing overflow: auto; // add position:fixed;

.parent {
    background-color: blue;
    height: 100px;
    width: 100px;
    padding: 20px;
}

.child {
    position: relative;
    background-color: red;
    height: 50px;
    width: 50px;
    padding: 10px;
    overflow: auto;
}

.circle
{
    position: fixed;
    background-color: green;
    left:8px;
    border-radius: 50%;
    height: 20px;
    width: 20px;
    background-color: green;
}
