Increase size of title font on home page feature slider

On the home page feature slider: https://catchthemes.com/demo/helena/ The title "Mountain Bar No-Bake Cookies"...is there a way to make the title larger? For instance, is there a way to make it roughly the same font size as the title on this page: https://catchthemes.com/demo/helena/2015/11/29/typesetting-design/ "Typsetting & Design" Many thanks!
