Basics of Height & Width in Css:

First, let’s take a look at the height and width individually and understand their role in web development.

Height Property in Css –

Height property specifies the vertical length of an element. By default when we create an element its height is set to ‘auto’. This means that the browser will decide how much height the should element get.

Syntax of height in Css –

height: value;

Width property in Css –

The width property specifies the horizontal length of an element. By default, it is also set to auto.

Values of the Height and Width property

  • Auto – This is the default. The browser calculates the height and width.
  • Length – This defines the height/width in px, cm, etc.
  • Percentage – This defines the height/width in percent of the containing block.
  • Inherit – This sets the height/width to its default value
  • Initial – This inherits the value passed to the parent element.
  • Let’s take a look at an example of these properties:

Max- Width / Height in css :

Max-width/height property is used to set the maximum width or height of the element.
This property is used to set the uppermost/maximum limit/length to the height or width property. It is primarily used so that the element does not cross a specific height or width

Syntax :

max-height: value ;
max-width : value ;
Min- width / height :

Min-width/height does the same job as of max-width/height but vice versa. This deals with the minimum length of height/width of elements to maintain a minimum ratio when the windows are much smaller.
