Changing Size Blog Title Links on Homepage (Dawn 5.0.0)

[MFJ]

Hi,

Today i wanted to change the size of the products titles on my homepage. It worked with this code in the base.css assets: 

a.full-unstyled-link {
font-size: 16px;
}

By doing this, the sizes of the titles of my blog posts, on the home page, changed automatically too. It's because they're also hyperlinks, just like the product titles on my homepage. How can i make the titles of my blog posts bigger back again, without changing the size of the product titles on the homepage?

I hope someone can help me with it. Thank you in advance!
