Forcing headings to wrap in html

Question

I have a web page that displays a pdf document. In the header there is an image and an h1 tag that contains a name. When the name is too long, it gets cut off. How can I force it to wrap to the next line instead so that the entire name is displayed? I tried inserting a style="white-space:normal" but it doesn't help. Any suggestions?

Answer 1

word-wrap:break-word;

Answer 2

It should have the combination of two:

word-wrap: break-word;
white-space: normal;
