HomeWeb Front-endCSS TutorialAn 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:

An example of using CSS3 to imitate WeChat chat bubbles

Xiaoyue Blog imitation WeChat chat interface

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  src="/static/imghwm/default1.png"  data-src="./img/c_pic.pn"  class="lazy"  ng- / 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  src="/static/imghwm/default1.png"  data-src="./img/u_pic.pn"  class="lazy"  ng- / 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  src="/static/imghwm/default1.png"  data-src="./img/c_pic.pn"  class="lazy"  ng- / 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  src="/static/imghwm/default1.png"  data-src="./img/u_pic.pn"  class="lazy"  ng- / 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!)

}
.leftimg {
 float: left;
 margin-top: 10px;
}
.rightimg {
 float: right;
 margin-top: 10px;
}
.leftd {
 clear: both;
 float: left;
 margin-left: 10px;
}
.rightd {
 clear: both;
 float: right;
 margin-right: 10px;
}

.leftd_h{
 width: 39px;
 height: 39px;
 border-radius: 100%;
 display: block;
 float: left;
 overflow: hidden;
}

.leftd_h img{
 display: block;
 width: 100%;
 height: auto;
}
.rightd_h{
 width: 39px;
 height: 39px;
 border-radius: 100%;
 display: block;
 float: right;
 overflow: hidden;
}

.rightd_h img{
 display: block;
 width: 100%;
 height: auto;
}

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.
