This is the css: 这是CSS：

.w3-teal{    background-color: #009688; color:#fff;}

Here is the working code: 这是工作代码：

 .w3-container, .w3-panel { padding: 0.01em 16px; } .w3-teal, .w3-hover-teal:hover { color: #fff!important; background-color: #009688!important; }

 <div class="w3-container w3-teal"> <h1>Header</h1> </div> <div class="w3-container"> <p>The w3-container class can be used to display headers.</p> </div>

Template 2 : 范本2：

 $('.ToggleDiv').click(function() { $('.menu').slideToggle(500); });

 * { padding: 0px; margin: 0px; box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; } .w3-container, .w3-panel { padding: 0.01em 16px; } .w3-teal, .w3-hover-teal:hover { color: #fff!important; background-color: #009688!important; } .ToggleDiv { position: absolute; top: 33px; right: 40px; z-index: 999; font-size: 28px; } .ToggleDiv a { color: #fff } h1 { margin: 20px 0; } .menu { width: 100%; position: absolute; left: 0px; right: 0px; top: 83px; background: #fff; display: none; color: #000; border: 1px solid #000; padding: 10px; }
