Width and Height of Elements in CSS

CSSWeb DevelopmentFront End Technology

The CSS height and width property are used to specify the height and width of an element respectively. We can also set the maximum and minimum values for these properties using the max-height, max-width, min-height, and min-width properties.

Syntax

The syntax of CSS height and CSS width property is as follows −

Selector {
   height: /*value*/
   width: /*value*/
}

The actual width and height of elements is calculated as follows −

Box SizeCalculation
Total Widthwidth + padding-left + padding-right + border-left + border-right + margin-left + margin-right
Total Heightheight + padding-top + padding-bottom + border-top + border-bottom + margin-top + margin-bottom

Example

The following examples illustrate CSS height and CSS width properties −
