The next thing is visual hierarchy. 1
So in terms of what is the most important, second most important, third most important thing on the page. 2
And on Android this is established using size. 3
So the title will always be bigger than everything else 4
and the subtitle will be slightly smaller and the text will be even smaller. But on iOS the visual hierarchy 5
is established using the weight of the typography. 6
So for example, the title will be something that's bold and the subtitle will be regular and the text 7
will be thin or light. And through the thickness of each of these letters essentially you're establishing 8
where you want the user's eye to flow from and to.
