Text-align=center Failure Reason

The Text-align property is a property set centered on an inline element, and margin:0 Auto is used for block elements to control the center;

I set a H2 tag when the text-align:center, but always appear in the center left position, the first reaction is possible style conflict, but after finding no conflict, and changed the P tag is not, and finally through the Google review element function to see a user Property settings for Agent style

Originally the browser made a H2 to set the block element so only need to re-cover the set to Inline-block just fine
