这次给大家带来css3的聊天气泡样式,做出css3的聊天气泡样式的注意事项有哪些,下面就是实战案例,一起来看一下。

在聊天的场景中,聊天内容需要用到气泡修饰,如下图。下面一一讲解。

css3的聊天气泡样式-LMLPHP

图片式:

第一个样式是京东客服,气泡的圆角和钩子都是用了图片。使用了一个table组合成了一个圆角的框框。lm样式拼出了钩子。

 <p class="jimi_lists clearfix">
                <p class="header_img jimi3 fl"></p>
                <table class="msg" cellspacing="0" cellpadding="0">
                    <tbody><tr><td class="lt"></td><td class="tt"></td><td class="rt"></td></tr>
                    <tr><td class="lm"><span></span></td><td class="mm"><span class="wel"><span class="visitor"><p>很抱歉,现在人工客服忙,让小JIMI为您解答吧。</p></span></span></td><td class="rm"></td></tr>
                    <tr><td class="lb"></td><td class="bm"></td><td class="rb"></td></tr><tr><td></td></tr>
                    </tbody>
                </table>
            </p>
            <p class="customer_lists clearfix">
                <p class="header_img jimi3" style="background: url(img/mine.jpg) no-repeat center;">
                    <p class="header_img_hover"></p>
                </p>
                <table class="msg" cellspacing="0" cellpadding="0"><tbody><tr><td class="lt"></td><td class="tt"></td><td class="rt"></td></tr><tr><td class="lm"></td><td class="mm">你好,我是stoneniqiu</td><td class="rm"><span></span></td></tr><tr><td class="lb"></td><td class="bm"></td><td class="rb"></td></tr><tr><td></td><td class="time"></td><td></td></tr></tbody></table>
            </p>

背景式:

第二种主要是使用了:before伪类画出了三角形,然后用定位拼在了一起。

  <p class="jimi_lists clearfix">
                <p class="header_img jimi3 fl"></p>
                <p class="bkbubble right">
                     <p>换个气泡如何</p>
                </p>
            </p>
            <p class="customer_lists clearfix">
                <p class="header_img jimi3" style="background: url(img/mine.jpg) no-repeat center;">
                    <p class="header_img_hover"></p>
                </p>
                <p class="bkbubble left">
                    <p>这个不错</p>
                </p>

样式:

  .bkbubble.right p:before, .bkbubble.left p:before {
      width: 0;
    position: absolute;
    top: 12px;
    border-style: solid;
    content: "";
  }
  .bkbubble.left {
      text-align: right;

边框式:

如果要求边框颜色和背景颜色不一样呢?上面的方法就不行了,因为用:before画三角形是利用border的原理,也就是说,在上面这种方式下,气泡边上的小三形是无法呈现两种颜色的,因为他只有一个border的颜色。那就要想办法凑出一个有边框的三角形了。

  <p class="jimi_lists lim_operator clearfix">
                <p class="header_img jimi3 fl"></p>
                <p class="lim_bubble lim_shadow"><p class="lim_dot">您好,请问有什么可以帮到您?</p></p>
                <p class="lim_tale"><p class="radiusborder"></p></p>
            </p>

1.先画一个小矩形。

.lim_operator .lim_tale {
    left: -1px;
    background-color: #c8f064;
    border-color: #a5d01b;
    margin-left: 70px;
}.lim_tale {
    position: absolute;
    width: 12px;
    height: 8px;
    overflow: hidden !important;
    top: 10px;
    z-index: 2;
    border-top-style: solid;
    border-top-width: 1px;
}

2.画出斜线。

css里面是没有斜线的,这里是用了一个园的弧形拼出来的。在一个大圆上,截取一段弧,就是一条斜线了。

.lim_operator .radiusborder {
    position: absolute;
    background-color: #EFF0F2;
    top: -29px;
    left: -94px;
    height: 160px;
    width: 160px;
    border-top-style: solid;
    border-top-width: 1px;
    border-right-style: solid;
    border-right-width: 1px;
    border-top-right-radius: 154px;
    border-color: #a5d01b;
}

叠加式:

原理就是相当于用before先画出一个有色背景,再用after画出一个白色背景,然后叠加错开顶部1-2px,这样就出现了一个有边框有背景的三角形。web 微信就是这种做法

.expression:before {
    content: '';
    position: absolute;
    left: 16px;
    top: 100%;
    margin-left: -7px;
    border: 7px solid transparent;
    border-top-color: #CFCFCF}.expression:after {
    content: '';
    position: absolute;
    left: 16px;
    top: 100%;
    margin-left: -7px;
    margin-top: -1px;
    border: 7px solid transparent;
    border-top-color: #FFF}
