The code above is some part of the full code at http://dot.kr/x-test/layOut01/

In domainLogo div, there are long text without any space.
If the text is short, no problems.
But when text is very long like the http://dot.kr/x-test/layOut01/, the last part of the text is behind guest-logIn part and go farther to right and the horizental scroll bar is created at the bottom of the browser.

Can I make the layout to automatically dropping the text when the text is very long inside the domainLogo div with your help?

You gave us the exact same links.

But you have a few options :).

word-wrap:break-word;
might be what you are looking for.

hope that helps
