Hi TushitaKBC,
I checked the UL text of the page that you have mentioned and it is indeed 14 pixels:
I used the WhatFont extension of the Google Chrome browser to determine the size of that section.
In general, if you want to have a CSS code which is restricted only to the page in question it is recommended that you go to the page listing and click on the Edit with Cornerstone link and in the Cornerstone screen bottom left screen you will find a CSS button which you can add your CSS there which will work only for that soecific page:
Important: You will encounter lots of problems on your website installation because you are using an old version of the theme and the new version of the Cornerstone and those are not compatible.
Please update the theme to version 6.1.6 and Cornerstone to version 3.1.6
Finally I will share with you some tutorials which will help you find the correct css-selectors and how to code CSS:
1- I have found the proper CSS code selector using the Chrome browser Developer Toolbar:
