The “Clearfix” hack is a technique used in CSS to clear or contain floated elements within a container. It addresses issues where a container does not fully encompass its floated child elements, causing layout problems, especially with collapsing margins.
There are various ways to implement the clearfix hack, but a common method involves adding a pseudo-element with the clear: both property to the container.
For Example
.container::after {
content: "";
display: table;
clear: both;
}
Features
- Clearing Floated Elements: The clearfix hack ensures that a container fully wraps around its floated child elements.
- Preventing Collapsing Margins: It helps avoid issues where margins of elements inside the container might collapse, affecting the layout.
