Website's puzzle description with a long sequence word causes page to expand in width quite a lot and doesn't wrap properly on Firefox version 41, other browsers (Opera and Chrome) fixes word breaking automatically. I look the html source and found that sequence word has style property 'word-break: break-word' which is incorrect and the word 'break-word' is not correct value on word-break property in CSS3 at the moment.
I think the value is suppose to be 'break-all' to make word wrapping work properly and fixes the problem.
