format sub-heading for featured content

Hi. How do I format the sub-heading on https://wellnesswarriorsboston.org/? I tried the following CSS, but it also changes the entry-summary for the Featured Content widgets. I just want to change the sub-heading. I think I am using the wrong element, but I'm not sure what would be correct. #featured-content p { font-size: 34px; } What am I doing wrong? Also, is there any way to insert a link into the heading? I don't think so, but I thought I'd ask. :-) Thank you. Alice
