portlet max width

[k3nnymusic]

I have got defined center region for portlets which size is 60% of all.
My portlet reading strings(articles) from database, and if one of string length is bigger than portlet width everything break, because portlet width increase. I need to configure const(but 60%) width of porlet. When string will be longer I want to move letters to the next line.
It isn't problem of layout because my cms portlet works fine.
Do you have got any suggestion?

Thanks!
