How to align itself NOT items in a center?

Question

When i use this snippet code

<h:panelGrid id="myGrid" columns="1"
rendered="#{myBean.showResults}" width="50%"
border="1" style="text-align: center;">  

The items of the panelGrid will be centralized
BUT
I want to centralize h:panelGrid itself in the center of the my XHTML page
Like this HTML code

<table id="myGrid" border="1" align="center">

Answer 1

Provided that it has a known width, give it a left and right margin of auto. This way it will center itself relative to the parent block element.

<h:panelGrid ... style="margin: 0 auto;">

Answer 2

wrap it in a panelgrid that has the size of your page and set the style of the parent grid to text-align center. Then your child grid will be centered on page (remove the text-align: center style from your child panelgrid
