Height and Width in CSS: A Practical Guide

Set height and width in CSS

height and width properties help set the height and width of elements in CSS. They can get the following values:

• auto - is the default mode in which the browser calculates the height and width
• length - value in px, cm.
• percent (%) - the value in percent

 div { 
  height: 200px; 
  width: 50%; 
  background-color: powderblue; 
 } 
 
 div { 
  height: 100px; 
  width: 500px; 
  background-color: powderblue; 
 } 

The image displayed on the browser of the above two examples

Note: height and width properties do not include padding, borders, and margins. They will determine the height / width of the area inside the element's padding, border, and margin.

Max-width setting

The max-width used to select the maximum width for the element, can use the values:

• length - length in px, cm.
• percen (%) - percent
• No - this is the default mode, meaning there is no maximum limit

Possible problems with the card

above is when the browser window is smaller than the element width (500px), the browser will add a vertical scroll bar to the rang. If using max-width, the browser will handle it better when the window is small.
