CSS margin Property
CSS margin property sets the margin for the HTML element on all the four sides.
margin is a short hand property to specify margin-top, margin-right, margin-bottom, and margin-left properties in a single shot.
margin property can be assigned with one, two, three, or four values.
margin: 35px 25px 45px 65px;
margin: 35px 25px 45px;
margin: 35px 25px;
margin: 35px;
We shall go through each of these scenarios with examples.
