How to Prevent Overflow:hidden from Hiding Floating Children in CSS?

Preserving Child Visibility in Overflow: Hidden Containers

In CSS, the overflow: hidden property conceals overflowing content within a container. However, when applied to parents of floating children, an intriguing effect occurs. The container automatically aligns itself adjacent to its floating siblings, creating a layout where a floating element's parent appears juxtaposed to it.

Problem Statement:

The challenge lies in maintaining this layout without concealing the children. By making the container overflow: visible, the container disregards the floating elements' flow, appearing on top of them.

Solution:

To overcome this, utilize the "clearfix" technique. By appending the "clearfix" class to the parent and removing overflow: hidden, the following CSS rules maintain the desired layout:

<code class="css">.clearfix:before,
.clearfix:after {
    content: ".";
    display: block;
    height: 0;
    overflow: hidden;
}
.clearfix:after {
    clear: both;
}
.clearfix {
    zoom: 1; /* IE < 8 */
}</code>

This approach effectively "clears" floating elements while preserving their layout, allowing the parent container to align itself adjacent to them without masking its children.
