Having problems understanding the center margin - task div wrapper center. margin:0 center;

Hi how are you?

Just trying to understand the margin centering rules in CSS.

Not sure about the correct layout here.

replace your 'center' keyword with 'auto'. ('center' is not usable for margin property)

'auto' will automatically calculate your margins for left and right here. And the margin will be same on both sides. The effect is that the #wrapper will be horizontaly centered then.

margin: 0 auto;

Also your last bracket is in the wrong direction.

Adapt your code as such

wrapper {
  max-width: 940px;
  margin: 0 auto;
  }
