Align to center div with variable size

Question

Hi, I have a div dad I’ve set up with min-width:800px and max-width:1400px, how do I make this div always align to the center?

Answer 1

Place the automatic margins:

.exemplo {
   min-width:800px;
   max-width:1400px;
   margin-left:auto;
   margin-right:auto;
}
