this missing one last word "me "

Many other words are also missing.

I give you full marks for plugging away at this but - do you realize that wrd_pr_linr = 4 will never look good for sequences of short or very long "words"

I a I a
highlighthighlight highlighthighlight highlighthighlight highlighthighlight

And even when it works (more or less) it will only look reasonably good for fixed-width fonts of certain sizes?

Hi,
fxm
Many thanks. I like what you have done with the max words


Can we have multiple char_max variables according to perhaps span class?

Hi

I will have more than one instance of text that needs to be treated like this. For example 1 large span and 3 smaller spans. What I really want is for this wrapping of text to be done by the size of the parent DIV.

But working with what here provided instead where it is based on the number of characters I would need to have different values for char_max according to the div it was in.

e.g. in the large area it might be .largespan char_max=40 while in the smaller areas it was .smallspan char_max=30

I hope that this makes sense.

One solution would be to give each span an id and add parameters to set_padd(). function set_padd(n,s) {}

set_padd(30,"span1")
set_padd(40,"span2")
