To sum up the above problems (by a trace ):
"The title is centered relative to the container, and the content is always aligned with the left of the title"
1. Table mode: http://jsfiddle.net/Tz23W/1/
2. inline-Block Mode: http://jsfiddle.net/dCxHW/2/
3. Width: Max-content
This problem leads to the relationship between the usage of Min-content, Max-content, and fit-content in css3 sizing module and css2.1 (these attribute values cannot be explicitly specified in CSS 2.1, can only be calculated ). Http://dev.w3.org/csswg/css3-sizing/#width-height-keywords
