Changing font in smartblog

[stoo_s]

Hi good people of the prestashop forum. I've already tried to contact the developer about this and had no response so am turning to the general community for help. I'm really annoyed at myself for not managing to work this fairly simple question out but where do i change the heading for each of the smartblog blocks displayed on the category pages?

 

As an example, let's say I want to change the current setting of h2 to h4 on the 'Recent Articles' block. I thought i could go to modules/smartblogpopularposts/views/templates/front/smartblogpopularposts.tpl and simply change h2 to h4 but this hasn't worked. I can't find the file i need to change anywhere. It's clear that each block needs to be changed individually and once I am pointed to one I'm sure i'll be able to find the others, but where to look?

 

Thanks in advance,

 

Stuart
