Question

<input type="checkbox" ng-class="{disabled: vm.reportSchedule.DailyOption === false}" name="dailyRunOnDays" 
           ng-model="vm.reportSchedule.DailyRunOnDays[day]">

我需要总是在顶部div id =“header”，总是在buttom div class ='inputContainer'和中间（占用页面的其余部分）div class =“chatArea”没有那个div class =“ chatArea“覆盖或被div id =”header“或div class ='inputContainer'覆盖。有谁知道这样做的css代码？

Answer 1

使用flexbox，这很容易实现。

将包含3个分区的包装器设置为display: flex;和   给它一个100% or 100vh的高度。包装的高度会   填满整个高度，display: flex;将导致所有   这个包装器的子节点具有适当的flex属性   （例如flex:1;）用flexbox-magic控制。

示例标记：

<div class="wrapper">
    <header>I'm a 30px tall header</header>
    <main>I'm the main-content filling the void!</main>
    <footer>I'm a 30px tall footer</footer>
</div>

相关的CSS将是：

.wrapper {
   height: 100vh;
   display: flex;

   /* Direction of the items, can be row or column */
   flex-direction: column;
}

header,
footer {
    height: 30px;
}

main {
    flex: 1;
}

快速谷歌搜索应该做..但你走了。一种方法。

body {
  padding-top: 60px;
  padding-bottom: 40px;
}

#header,
#footer {
  width: 100%;
  position: fixed;
  background: #333;
  padding: 10px 0;
  color: #fff;
}

#header {
  top: 0;
}

#footer {
  bottom: 0;
}

.chatArea {

  margin: 0 auto;
}

Flexbox救援。

使用您的结构。颜色编码。

＆＃13;

body{display:flex; flex-direction: column; height: 100vh;}

#header{height: 100px; background: green;}
.chatArea{flex-grow: 1; align-self:stretch; background: blue;}
.inputContainer{height: 100px; align-self: flex-end; width: 100%; background: red;}

＆＃13;

<head>
  <meta charset="UTF-8">
  <title>Chat</title>
  <link rel="stylesheet" href="css/style.css">
</head>

<body>
  <div id="header">
    <h1 id="titleRoom"></h1>
    <h3>Online Users:</h3>
    <div id="online_users"></div>
    <br>
    <button id="buttonRoom" type="button" name="button">Create Chatroom</button><button id="buttonLobby" type="button" name="button">Back Lobby</button>
  </div>
  <div class="chatArea">
    <ul class="messages"></ul>
  </div>
  <div class='inputContainer'>
    <input class="inputMessage" placeholder="Type here..." /><button id="sendButton" type="button" name="button">Send</button>
  </div>
  <script src="https://code.jquery.com/jquery-1.10.2.min.js"></script>
  <script src="/socket.io/socket.io.js"></script>
  <script src="/js/client.js"></script>
</body>
