Pattern

External links

Links that leave the site open in a new tab and say so with an arrow when they are a call to action.

Rules

New tab
Links to other sites use target="_blank". Links within niklausgerber.com open in place (relative paths, no domain).
rel
rel="noopener noreferrer". Some older links on the Unresolved page carry only noopener; align them when the page is next edited.
Arrow
Calls to action that leave the site end in “↗” after a no-break space, in <span aria-hidden="true">: “Order on Amazon ↗”, “Get it on the App Store ↗”. Plain text links carry no arrow.
Referral
Playground links add ?ref=niklausgerber.com.
Email
Shown as text and linked with mailto:, always inside <!--sse--> … <!--/sse-->.
Domain
Every absolute URL to the site itself uses https://niklausgerber.com, never www.
