How to create chat bubbles like facebook Messenger

Question

How would I create chat bubbles like this. More specifically how to group two ore more consecutive messages by one type of user into a bubble as a whole. For exampl

Answer 1

Here is a pure css solution, but it hinges on your ability to detect and apply the chat__bubble--stop class when the final message of a group is sent. Unfortunately the pseudo class :last-of-type can't be used; as others have pointed out, the last message in a group isn't necessarily the last of the conversation. It also makes use of the adjacent sibling selector (+).

.chat {
  list-style-type: none;
  width: 20em;
}

.chat__bubble {
  margin-bottom: 3px;
  padding: 5px 10px;
  clear: both;
  border-radius: 10px 10px 2px 2px ;
}

.chat__bubble--rcvd {
  background: #f2f2f2;
  color: black;
  float: left;
  border-bottom-right-radius: 10px;
}

.chat__bubble--sent {
  background: #0066ff;
  color: white;
  float: right;
  border-bottom-left-radius: 10px;
}

.chat__bubble--sent + .chat__bubble--sent {
  border-top-right-radius: 2px;
}

.chat__bubble--rcvd + .chat__bubble--rcvd {
  border-top-left-radius: 2px;
}

.chat__bubble--stop {
  border-bottom-right-radius: 10px;
  border-bottom-left-radius: 10px;
}
