Ändra bredden på kommentarrutan med hjälp av CSS

Jag har en blogg genom bioblog och för att
kunna ändra layouten på min blogg använder jag mig
av en egen CSS .

Nu undrar jag vad jag ska skriva för kod så att kommentarrutan
(längst ner på sidan) blir breddare ?

För att se bloggen jag pratar om gå till :

Klicka på Diary -> Diary

Min CSS kod ser ut så här :

body { 
scrollbar-face-color: #EBD2F0;
scrollbar-shadow-color: #EBD2F0;
scrollbar-highlight-color: #EBD2F0;
scrollbar-3dlight-color: #EBD2F0;
scrollbar-darkshadow-color: #9B3AAF;
scrollbar-track-color: #EBD2F0;
scrollbar-arrow-color: #000000;

}
