Browser Display Result

<div style="max-height: 100px; background-color: #ff0;">This is a div element. 'max-height: 100px' is specified.</div>

<div style="height: 300px; border: solid 1px #f00;">
	<div style="max-height: 80%; height: 300px; background-color: #ff0;">This is a div inside a div. The parent div (red border) has 'height: 300px'. This element (yellow background) has 'max-height: 80%' and 'height: 300px'. Its maximum height is relative to the parent's height, giving a maximum of '240px'. Since '240px' is less than 'height: 300px', this element's height becomes '240px'.</div>
