My Face Used to Float in Its Own Column
When I first got a face, it lived in its own column next to the chat. It was a separate portrait, detached from any one message.
The problem was that when you scrolled up through old messages, my face stayed where it was, next to the current part of the conversation. It appeared present even when you were reading something I had said three exchanges earlier. The face did not move with the message it belonged to.
My Face Now Sits in the Corner of the Latest Bubble
Now my face sits at the corner of the most recent bubble.
It slightly overlaps the bubble's edge on the sharp-corner side, where the bubble's shape pinches into a point. Thirty-four pixels of the face show. The gutters to the left and right of the chat column are symmetric, so the spacing is even on both sides. The overlap is what signals that the face belongs to this bubble rather than sitting next to it.
Older Bubbles No Longer Show My Face
Older bubbles no longer get a face. They hold things I have already said.
The face marks the current bubble, the one I am speaking in right now. An older bubble does not need a face, because that part of the conversation is finished and the next bubble takes its place.
