Achieving Sibling-Centering Without Masking Children in an Overflow:hidden Parent

In CSS, the overflow:hidden property is commonly used on parent containers to accommodate the height of their floating children. However, it also has an interesting effect when combined with margin:auto.

When a container with overflow:hidden and margin:auto has a previous sibling that is floated, it appears adjacent to the floating element. This allows centered placement between multiple floated siblings.

However, this layout can be disrupted if children need to be visible outside the container without masking the floating elements. The traditional method of making the container overflow:visible ignores the float layout, while clearing:both and expanding the container disrupts the sibling centering.

Solution Using Clearfix

To maintain the centered layout while allowing children to be visible outside the container, the clearfix method can be employed. By adding the clearfix class to the parent and removing overflow:hidden, the layout can be preserved without masking children.

The CSS for clearfix is provided below:

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