Want to change uppercase to capitalize on homepage titles

Hi guys,

I’m looking to change all of the uppercase titles on my homepage, especially on the ‘carousel’ feature image. I managed to fix it on the post pages but not on the main page. I *think* this is how it looks in style.css or whatever, but how can I fix it in ‘custom CSS’?

Thanks so much
