An example of using CSS3 to imitate WeChat chat bubbles

Today I would like to share with you a small case from a project I just worked on. Because we are working on a chat function, the previous chat page UI was very ugly, so I will not show it to you here.

Now I will teach you how to use css3 to create a page that is the same as the WeChat chat interface.

First of all, let me show you what the page looks like, as shown below:

page This is roughly what it looks like, let’s learn the production steps together.

Part One: HTML

<div class="leftd">
    <span ng-class="leftd_h">
        <img  ng-src="./img/c_pic.pn" / alt="An example of using CSS3 to imitate WeChat chat bubbles" >
    </span>
    <div class="speech left" ng-class="speech left"> 
        二货，你看你傻样！
    </div>
</div>
<div class="rightd">
    <span ng-class="rightd_h">
        <img  ng-src="./img/u_pic.pn" / alt="An example of using CSS3 to imitate WeChat chat bubbles" >
    </span>
    <div class="speech right" ng-class="speech left"> 
        嘻嘻嘻嘻。。。。。。
    </div>
</div>
<div class="leftd">
    <span ng-class="leftd_h">
        <img  ng-src="./img/c_pic.pn" / alt="An example of using CSS3 to imitate WeChat chat bubbles" >
    </span>
    <div class="speech left" ng-class="speech left"> 
        笑什么笑，没看到本宝宝今天变漂亮了吗？
    </div>
</div>
<div class="rightd">
    <span ng-class="rightd_h">
        <img  ng-src="./img/u_pic.pn" / alt="An example of using CSS3 to imitate WeChat chat bubbles" >
    </span>
    <div class="speech right" ng-class="speech left"> 
         不不不，每天你都很漂亮的啦！
    </div>
</div>

Part Two: CSS3

PS (This is also the most important part, so I’ll show you all the code!)

Here are basically small bubbles made using CSS pseudo-class elements. There are many cases on the Internet where the user's chat avatar is used as the background image, but I feel that this is not very suitable in actual projects, so I made some modifications to make it more practical.
