Contextual Alternates are another fun OpenType feature enabled by default throughout Avalon. Below are the words “Contextual Alternates” written with the beautiful Ambiance BT with contextual alternates enabled:

Contextual alternates are enabled by default, so the markup I used for this is quite simple:

<TextFlow FontFamily="Ambiance BT" FontSize="30">

<TextFlow FontFamily="Ambiance BT" FontSize="30"
  Typography.ContextualAlternates="False">
  Contextual Alternates
</TextFlow>

I’ll close this post with an animated screenshots of typing the word "Effect" with alternates enabled (especially the transition from "E" to "Ef"):
