Hello all! I'm a very curious person who loves to learn about design and understand how certain design choices are made. I'm particularly curious about typograhy choices. I've seen that in this page https://www.invisionapp.com/inside-design/how-to-build-a-portfolio-when-youre-new-to-design/ you use a combination of Eina and Maison Neue. From what I understood, they're both Grotesque Sans Serif typefaces. What I was wondering, what would lead to pair those typefaces? Also, I've read that pairing typefaces from the same classification(both sans or serif) was bad, because they can clash. Is this always true? I would assume that no, if you're using both, they would be a good match. As so, what makes them a good match? Is it because they're both same classification, grotesque?
