Inline Block Spacing with Justify

View the page source to see the 'fix'. Note that I strongly advise people to comment out the white space instead of using a CSS solution, but if that's not possible, this is my best attempt.

Each example box is 200px wide.

Based on this idea, but with my spacing fix applied to solve one of the problems with it.

Without spacing fix:

Inline-block item 1 Inline-block item 2
With 2 lines
Inline-block item 3 ...

Without spacing fix and % boxes:

Inline-block item 1 Inline-block item 2
With 2 lines
Inline-block item 3 ...

With spacing fix:

Inline-block item 1 Inline-block item 2
With 2 lines
Inline-block item 3 ...

With spacing fix and % boxes:

Inline-block item 1 Inline-block item 2
With 2 lines
Inline-block item 3 ...

And for comparison:

Commented out white space in this case prevent the technique from working:

Inline-block item 1Inline-block item 2
With 2 lines
Inline-block item 3...
