How Can I Make a Floated Div Expand to the Height of Its Parent?

Expanding Floated Div Height to Match Parent

Floating child elements can disrupt the vertical alignment of parent containers. To address this issue and ensure that the height of a floated child div expands to match its parent, follow these steps:

1. Set Parent Properties:

Add the following CSS properties to the parent element:

.parent {
    overflow: hidden;
    position: relative;
    width: 100%;
}

• overflow: hidden prevents child elements from overflowing outside the parent container.
• position: relative establishes a relative positioning context for the child elements.
• width: 100% ensures that the parent div occupies the full width of its container.

2. Configure Floated Child:

For the floated child div (e.g., .child-right), apply the following CSS properties:

.child-right {
    background: green;
    height: 100%;
    width: 50%;
    position: absolute;
    right: 0;
    top: 0;
}

• background: green assigns a green background color for visibility.
• height: 100% sets the height of the child div to match the height of its parent.
• width: 50% defines the width of the child div as half the parent's width.
• position: absolute removes the child div from the normal document flow and positions it absolutely within the parent container.
• right: 0 aligns the child div to the right edge of the parent.
• top: 0 aligns the child div to the top edge of the parent.

By implementing these CSS properties, the floated child div will automatically expand its height to match that of its parent, ensuring a vertically aligned layout.
