Increase font size

Hi,
I am using Google Font Roboto Condensed with Normal 400 and all the html containers selected as shown in image which I have attached. http://imgur.com/Mg6Zerb
I do not use any <P> tag in my post and but in HTML source all the text comes under p. How can I increase the font size of this text.
My URL is – http://www.monkshouts.org/how-to-setup-git-version-control-with-eclipse/
Kindly tell me how to fix this.
