Yeah, lol :-)

The first thing I can remember of (Davi reverted my commit... "unstable
code"... lol, I can't convert the whole webapp all at once! :-D ) is..
tables :-)

HTML:
<table bgcolor="{$webpage->theme->contentBGcolor}" cellpadding="0"
cellspacing="0" rules="none" border="0">

I converted it into XHTML this way:

<table style="background-color:{$webpage->theme->contentBGcolor};border:0;">

Notice that we lost the information provided by cellpadding, cellspacing
and rules. There are no equivalents in CSS, IIRC.

Moreover, look at this sample code (I've found different pieces like this):

<img src="bla.png" width="90" height="120" align="left" alt=""
border="1" hspace="0" vspace="0">

In XHTML it would be:

<img src="bla.png width="90" height="120" align="left" alt="image"
style="border:0;position:relative;left:0;top:0" />

(I don't really remember if "align" is an acceptable attribute of img)

Now, see that I used position:relative, with left and top = 0px instead
of hspace and vspace... is that correct? I'm not sure.

Cheers,
David

P.S.: in my opinion, it would be better using DIVs instead of TABLEs.
But I think it's a lot of work

P.P.S.: I'm stopping my work, as we still have to decide whether to
carry it on.
