How to create chats like facebook messenger

Question

How to create chat bubbles like this. More specifically, how to group two or more consecutive messages by one type of user into a bubble as a whole. For example, for SENDER, the first message has a lower right border of 0, the messages between them have a top right, the bottom as a border radius of 0, and the last has a top right 0 border radius. Should I use javascript or can this be done using css.

HTML structure ca be

<ul>
 <li class="him">By Other User</li>
 <li class="me">By this User, first message</li>
 <li class="me">By this User, secondmessage</li>
 <li class="me">By this User, third message</li>
 <li class="me">By this User, fourth message</li>
</ul>

What css class / styles should I use?

Answer 1

This is a fairly simple example, but it should explain all the basic principles that you need.

ul{
  list-style: none;
  margin: 0;
  padding: 0;
}

ul li{
  display:inline-block;
  clear: both;
  padding: 20px;
  border-radius: 30px;
  margin-bottom: 2px;
  font-family: Helvetica, Arial, sans-serif;
}

.him{
  background: #eee;
  float: left;
}

.me{
  float: right;
  background: #0084ff;
  color: #fff;
}

.him + .me{
  border-bottom-right-radius: 5px;
}

.me + .me{
  border-top-right-radius: 5px;
  border-bottom-right-radius: 5px;
}

.me:last-of-type {
  border-bottom-right-radius: 30px;
}

<ul>
 <li class="him">By Other User</li>
 <li class="me">By this User, first message</li>
 <li class="me">By this User, secondmessage</li>
 <li class="me">By this User, third message</li>
 <li class="me">By this User, fourth message</li>
</ul>

Answer 4

Here is a clean css solution, but it depends on your ability to detect and apply the class chat__bubble--stopwhen sending the final group message. Unfortunately, the pseudo-class :last-of-typecannot be used; as others have pointed out, the last message in the group is not necessarily the last of the conversation. It also uses a nearby 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;
}

<ul class="chat">
 <li class="chat__bubble chat__bubble--rcvd chat__bubble--stop">What are you up to?</li>
 <li class="chat__bubble chat__bubble--sent">Not much.</li>
 <li class="chat__bubble chat__bubble--sent">Just writing some CSS.</li>
 <li class="chat__bubble chat__bubble--sent">I just LOVE writing CSS.</li>
 <li class="chat__bubble chat__bubble--sent chat__bubble--stop">Do you?</li>
 <li class="chat__bubble chat__bubble--rcvd">Yeah!</li>
 <li class="chat__bubble chat__bubble--rcvd">It super fun.</li>
 <li class="chat__bubble chat__bubble--rcvd chat__bubble--stop">... SUPER fun.</li>
</ul>
