How to Allow Elements to Overflow a Container with `overflow: hidden`?

Container Overflow Control for Specific Elements

You may encounter situations where you have a container with specific height and width dimensions and overflow:hidden to conceal any elements that exceed its boundaries. However, you may also want to allow certain elements within the container to extend beyond these boundaries.

To achieve this, employing the approach of keeping the overflow:hidden element with position:static and positioning the overflowing element relative to a higher parent (rather than the overflow:hidden parent) proves effective. For example:

<code class="css">.relative-wrap {
    position: relative;
}

.overflow-wrap {
    height: 250px;
    width: 250px;
    overflow: hidden;
    background: lightblue;
}

.respect-overflow {
    position: relative;
    top: 75px;
    left: 225px;
    height: 50px;
    width: 50px;
    background: green;    
}

.no-overflow {
    position: absolute;
    top: 150px;
    left: 225px;
    height: 50px;
    width: 50px;
    background: red;
}</code>
<code class="html"><div class="relative-wrap">
    <div class="overflow-wrap">
        <div class="respect-overflow"></div>
        <div class="no-overflow"></div>
    </div>
</div></code>

In this example, the .relative-wrap div serves as the higher parent with position: relative. Within .relative-wrap, the .overflow-wrap div (with overflow:hidden) is positioned with position:static. The overflowing elements (in this case, .respect-overflow and .no-overflow) are then positioned relative to .relative-wrap (their grandparent element) using position: relative for .respect-overflow (which respects the boundaries of .overflow-wrap) and position: absolute for .no-overflow (which can extend beyond the container boundaries).

This approach effectively allows you to have elements within a container with overflow:hidden that can protrude beyond its boundaries, giving you greater flexibility in your layout and design.
