Do you want to make it once on page loading or at any time after page
loaded?

It is html builder to create a html file. The reason is my content
change often. sometimes may be just
one line or two, if set row=10, it wast more space.
what I basic idea is use string length to check my contents (may use a
function to check it), then based on that assign a var. to rows. Is
it possible? also if the content is longer that 10 rows, use
scrollbar.
