In this tutorial will learn how to center div,span or any element horizontally using css3 in just few lines of code.

So, lets start with css,
.horizontal-center {
position: relative;
left: 50%;
transform: translateX(-50%);
-moz-transform: translateX(-50%); /* For mozilla support */
-webkit-transform: translateX(-50%); /* For safari support */
-ms-transform: translateX(-50%); /* For IE support */

Can’t you just use “margin: auto;” alone for the same purpose?
Yes we can do, by applying “margin : 0px auto;”.
but in some cases margin doesn’t work.
This one is just different approach for align horizontally center..
Good to see a different approach! Better to use “margin : 0px auto;”. But when you are using pop ups, this approach will be useful!
Yes right Joby Tom.
Thanks.
