change page content with div tag

[techie_ns]

Hi there,

There might be some code out there but I was unable to find it.

I want to change page content based on a click on some text. all content and all text must be on the same page.

e.g. there are three column of a table

no1 no2 no3

with click on no1 I want to display a login screen, with click on no2 display text test test.

Thanks in advance.
