8 Tips to Make Your Website Feel Like an iOS App

Very nice video by Sam Selikoff in which he sets up a web manifest to make his site feel more app-like. Great production quality.

There are some tweaks I’d suggest though:

  1. Fixate the header using position: sticky; instead of position: fixed;. No need for that extra margin on the content then. Update: See note below

  2. Don’t set the header height to a fixed number, as not all devices have (equally sized) notches. Use the User Agent Variable safe-area-inset-top instead, and apply it as the top padding:

    header {
      padding-top: env(safe-area-inset-top);
    }
  3. Don’t disable scaling in case your app does not follow the system font sizing — which it does not by default. To make it do follow the system font sizing, use this snippet:

    @supports (font: -apple-system-body) {
      html {
        font: -apple-system-body;
      }
    }

    💡 You can still override the font-family after that. That way you can have your custom font and also follow the preferred system Text Size

As an extra: to prevent that long-press behavior when the app is not added to the home screen, set -webkit-touch-callout: none; on the links.

On Twitter Sam pointed me out that when using position: sticky; there’s an issue with overscroll/bounce: The header will shift down along with the body as you do so.

In theory one could easily fix this by applying some overscroll-behavior on the body. However, as Safari does not support overscroll-behavior you’ll have to resort to a hack to prevent overscrolling in Safari. But, as that hack relies on 100vh — which Safari also doesn’t understand properly — you’ll have to use another hack to make Safari use the correct value for 100vh.

(* mumbles something about Safari being the new IE6 *)
