Do you mean direction for left-to-right (english, romance langs, easterne european langs) vs right-to-left (arabic, hebrew, japanese (i think)) language orientation?
Edit: Hmph, stuff that does things like that creeps me out. Firefox's "view selection source" rewrites the HTML it shows too. Took a while to figure that one out.
Ooooooh. I see. It's a shame -- the Web Developer Toolbar is such an awesome tool. For weeks now I have assumed that developers knew some secret that I didn't and that my style sheets would be crappy and amateurish until I started inserting my own margin-left-ltr-source properties.
Anyone know of a way to get around this, to see the CSS as it was originally written? I think there's no better learning tool than to look at the style sheets of really well designed sites.
I believe the "-ltr-source" stuff only shows up when you use the "View Style Information" option of the WDT. If you choose "View CSS" or "Edit CSS", you'll view the actual CSS as it is written for the entire webpage ("Find" doesn't work with "Edit CSS" so I usually go with "View CSS")
