Content does not wrap to the viewport/parent element
What is it?
The NOBR element indicates to the browser that all contents within its
boundaries will not have linebreaks inserted. This behavior overrides the
default line-wrapping mechanism that is intrinsic to HTML and can yield
odd visual results for long runs of content.
DTD NOTE: The only DTD to include this
element is the Internet Explorer 3.0 DTD - It incorrectly treats it as a
stand-alone element even though both Netscape's original description and
observed behavior for both Internet Explorer and Netscape show it is
definitely a container element. I have decided to treat it as a container
along the model of other character level formatting tags (like B or I)
since there is no intrinsic modifying block behavior.
