【css3】--四种气泡

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。

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。

 <div class="jimi_lists clearfix">
                <div class="header_img jimi3 fl"></div>
                <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>
            </div>
            <div class="customer_lists clearfix">
                <div class="header_img jimi3" style="background: url(img/mine.jpg) no-repeat center;">
                    <div class="header_img_hover"></div>
                </div>
                <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>
            </div>
