Overall Structure

  1. 1.
    We have three structures: default, collapsed navigation, and fullscreen.
  2. 2.
    Each structure is split by:
    1. 1.
      App frame: global elements including navigation and top bar. More here.
    2. 2.
      Page content: Within the app frame - an inner area comprised of page-specific content. See more about how the page content here.
Default
Collapsed
Fullscreen

Width and Responsiveness

  1. 1.
    We use page content gutters to deal with different screen sizes. The gutters expand to accommodate larger screens and the content has a fixed maximum.
  2. 2.
    We actively support screens from 1280px by 800px up to 1920px by 1080px, which means we easily fit into 96% of desktop screens. We haven't prioritized responding to tablets because we we don't have feedback that people are using Customer.io on tablets.
  3. 3.
    We design wireframes in 1366px by 768px screen size because it is the most commonly used screen size (35% of desktops).
