Horizontal centering TWO vertically placed child divs inside parent DIV

How to horizontally center two child DIV elements place vertically one after another inside a PARENT DIV container element and the child DIVs will be exactly horizontally centered.

  • PARENT DIV is of 400px width and height.
  • Child is of 200px width and height.
  • We have set the positioning property : RELATIVE of Parent div.
  • That means inner DIVs inside parent will be placed relative to parent / container div.

Then we have placed a wrapper just outside of two vertical DIVs. Two child vertical DIVs are of margin: 0 auto , which places child DIVs with respect to WRAPPER divs.

We have tested the following codes in IE6,Opera 10, Firefox 4 and I hope it will work in other browsers too.
