CSS width Property

CSS's width property is used to specify the width of text and images. The width of text and images can be specified in pixels (px), percentages (%), centimetres (cm), and other units.

Padding, borders, and margins are not included in the width property. The min-width and max-width properties override the width property.

The width property sets the width of the content area by default, but if the box-sizing property is set to border-box, it sets the width of the border area.
