Whan studying and testing code for lateral notes from suggestions into fr.source, I noted that the code is extremely simplified simply stating width of our div class="testi" (used for the large majority of texts in Ns0) as* width:45%* instead of *width:33em*.
All the code needed for a right lateral note, with a main div *width:45%*, is:
<span style="position:absolute; left:74%; width:13%; text-align:left; text-indent:0em; line-height:110%"><small>{{{1|test}}}</small></span>
where param 1 is the text of the note, with no need of additional templates.
My question is: is there any drawback using *percent *value for a div width instead of *em* unit? I can't find any so far.
