Print two different things in a single line on a web page

If I have to print something like this --

Reason :  reason number 1
          reason number 2
          reason number 3

Code :    code number
Remarks : remark

So Reason, Code, and Remarks are headings, and thus I have them in tag, rest of the things such as - reason number 1, reason number 2, code number and remark are the values.

Now, If I use for the heading, the value automatically goes to a new line, What if I want to print them as key-values in a single line. How can I do so.

Preferably without float.
