[pmwiki-users] finding lines with space in front

[jdd]

Hello,

I have layout problems with a page:

http://new.dodin.org/wiki/index.php?n=Doc.TraductionDeLaPageSurSuseParDavidKrider

I beg I forgot a blank space in front of some long line, but can't 
find it.

as a more general solution, could it be possible to have such line 
with a grey background, like mediawiki?

does this have to be changed in the skin or in the main css? what to 
serach for?

thanks
jdd
