最近做一个HybridApp，前端有一个群聊的功能，于是就想模仿微信的聊天界面，先看效果图：
HTML代码：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>HTML5实现微信聊天气泡效果</title> <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width"> <link rel="stylesheet" href="chatbox.css"> </head> <body> <!-- Left --> <div class="chat-sender"> <div><img src="img/ben.png"></div> <div>阿奔 Ben</div> <div> <div class="chat-left_triangle"></div> <span> 苹果增加三款配件的颜色选项</span> </div> </div> <!-- Right --> <div class="chat-receiver"> <div><img src="img/max.png"></div> <div>好人·马克思</div> <div> <div class="chat-right_triangle"></div> <span> 但是如果你正在再发新的APP跨平台项目，我建议你考虑一下Ionic2/Ionic3。 ionic2/Ionic3的架构使得“单一职责原则”得到了体现，组件、页面之间相互独立，有利于内聚和解耦。</span> </div> </div> <!-- Right --> <div class="chat-sender"> <div><img src="img/adam.jpg"></div> <div>阿达姆 Adam</div> <div> <div class="chat-left_triangle"></div> <span> 一款接近原生的Html5移动App开发框架</span> </div> </div> <!-- Notice/Center --> <div class="chat-notice"> <span>2017年12月10日 23:13</span> </div> <!-- Left --> <div class="chat-sender"> <div><img src="img/perry.png"/></div> <div>佩里 Perry</div> <div> <div class="chat-left_triangle"></div> <span> Ionic遵循视图控制模式，通俗的理解和 Cocoa 触摸框架相似。在视图控制模式中，我们将界面的不同部分分为子视图或包含其他视图的子视图控制器。</span> </div> </div> <!-- Left --> <div class="chat-sender"> <div><img src="img/mike.png"></div> <div>麦克</div> <div> <div class="chat-left_triangle"></div> <span> 你可以用ionRefresher指令实现拉动刷新，并可以用ionInfiniteScroll指令实现无限滚动。</span> </div> </div> <!-- Right --> <div class="chat-receiver"> <div><img src="img/max.png"></div> <div>好人·马克思</div> <div> <div class="chat-right_triangle"></div> <span> 最后但并非最不重要的是</span> </div> </div> <!-- Notice/Center --> <div class="chat-notice"> <span>你被群主移除群聊</span> </div> </body> </html>
