Source Serif Pro type weights
Source Serif Pro is our primary serif font and should be used in body copy as a primary serif font in your web and social media communications. Because it is part of the Source typeface family, it complements well with Source Sans in headlines and as small elements in layouts.
This font can be used for some headlines, callouts and dense body copy.
