When using flexbox, if you set the margin property to auto, it will automatically adjust the margins for both the horizontal and vertical axes.

Structure in HTML:

<div class="parent">
    <div class="child">
    </div>
</div>

CSS Style:

html, body {
    width: 100%;
    height: 100%;
}
.parent {
    display: flex;
    width: 100%;
    height: 100%;
    border: 5px solid red;
}
.child {
    width: 100px;
    height: 100px;
    margin: auto; /* Automatically adjusts margin for horizontal and vertical axis */
    border: 5px solid blue;
}
