Change Timeline title text size specificly

Hi

I am able to change the size of the date posted text on the timeline of the homepage but whenever I try to change the size of the title text it changes the size of both the title text and the date text to be the same size. I do not want them to have the same size text as each other so can I please have the css code that targets the timeline title itself. http://www.bradahad.com
