Looking at the MDN article for CSS margin it says:
margin
When two values are specified, the first margin applies to the top and bottom, the second to the left and right.
Citation: developer.mozilla.org/en-US/docs/W...
So margin: 0 auto is the same as the following 4 properties:
margin: 0 auto
margin-top: 0; margin-right: auto; margin-bottom: 0; margin-left: auto;
When margin-left and margin-right are both auto that will usually center-align a Block Level Element, like a <div>.
margin-left
margin-right
auto
<div>
Thanks!
