cubicweb #1373338 Have a way to avoid a horizontal slider [open]

On a reasonable resolution (1024x768 see http://www.strategiesdunet.com/blog/41-infos-du-net/68-statistiques-de-resolution-decran-des-internautes-en-mars-2009 ) we should not have a horizontal slider. If there is a way to be sure of this, it would be a nice feature in cubicweb.

An example I can think of is the code snippets, when logs are pasted for instance, that make a solid box that makes the page way too large (the boxes on the right disappear). Either have a linebreak or maybe a slider inside that zone ?
