Dear Ahmed, Mete,
I think Ahmed is trying out to do it differently from what I did. If I
understood correctly, you are trying to create and application that
will highlight tajweed rule under gnome, right?
What I idi is something very basic. I just create an html page so that
each character will have different colors, nothing to do with tajweed
rules. However, if we encode the text to correcpond to tajweed rules,
we will have the correct colors for it.
Anyway, it only works under IE. I use the <span> tag for each
character. Under firefox, this will lead to the characters to take the
isolated forms only, thus not very usefull. I did not try it under
