Nested headers with different height

Hi,

I have three nested headers and all in same height. But i need my second header to be small then other headers.
How to fix this?Could you please suggest how to fix it?

All my headers are dynamic headers.

Hi @akilareddy.gaddam

There is an option to change the height http://jsfiddle.net/tshz8nL1/ but minimum is 23px for the headers
