Change K2 titles to lowercase, style H1, H2...

Hi, I am using Joomla 3, K2 2.6.9 and News 2 template.
I would like to change: K2 titles to lowercase, style H1, H2...- change font and size. Would you help me with that?

Hi,
if you have some basic skills with CSS,
start from this guide: https://www.gavick.com/documentation/jo ... t-size-etc

if not, time to buy a book about CSS

And I think it is time for you to buy a book about how not to be bored by customers questions

Yes, I guess check those two:

1) First about CSS / CSS3 : http://eu.wiley.com/WileyCDA/Section/id ... ?query=css
2) and second https://www.packtpub.com/web-developmen ... essentials

Thanks, Oskar
