margin 0px auto code example
Example 1: margin 0 auto
Specifying 0 tells the browser to set the top and bottom margin to 0.
Specifying auto tells the browser to automatically determine the left
and right margins equally.
It's the same as:
margin-top:0;
margin-bottom:0;
margin-left:auto;
margin-right:auto;
Example 2: margin 30px auto
/* La propriété s'applique aux quatre côtés */
margin: 1em;
/* vertical | horizontal */
margin: 5% auto;
/* haut | horizontal | bas */
margin: 1em auto 2em;
/* haut | droit | bas | gauche */
margin: 2px 1em 0 auto;
/* Valeurs globales */
margin: inherit;
margin: initial;
margin: unset;
