I. Description of the problem
In the page display module, when the need to give the child a box when about margins set, there may be a good parent box can not accommodate children of the box, as follows:
Second, the problem analysis
The fifth child count its right margins, line width in the sub-elements of the box than the parent, so the fifth sub-elements resulting in wrap.
Third, the solution
Since margins are not visible in the visual presentation, it may be the width of the parent box increases, the amount of the fifth sub-elements out of the plurality right margins, so as to ensure line can accommodate five sub-box
Fourth, there is a problem (guess)
Applies to: Parent box style (background color) consistent with the style on stage
If demand exists: Parent box and then on a style different from the present, the parent will result in inconsistent with the width of the box up and down, so that the page uncoordinated
