The Style marginTop property in HTML DOM is used to set or return the top margin of an element. 

Syntax:

  • It returns the marginTop property.
object.style.marginTop
  • It is used to set the marginTop property.
object.style.marginTop = "length|percentage|auto|initial|
inherit"

Return Values: It returns a string value that represents the top margin of an element

Property Values:

  • length: It is used to specify the margin in fixed units. Its default value is 0. 
  • percentage: It is used to specify the amount of margin as a percentage relative to the width of the containing element. 
  • auto: If the value is set to ‘auto’, then the browser automatically calculates a suitable value for the margin size. 
  •  initial: It is used to set the property to its default value. 
  •  inherit: It is used to inherit the value from its parent element. 

Example: In this example, we are using object.style.marginTop = length property.
