我是网络开发的新手，我正在尝试使用 SQL 创建一个简单的聊天页面。这是我目前拥有的:Codepen
HTML:
<body>
<div id="overlay"></div>
<div id="header">
<div id="logo">
<a href="http://csgovoid.net"></a>
</div>
</div>
<div id="chat_extended">
<div id="chat_area"></div>
<input id="chat_input" type="text" placeholder="Chat...">
<button id="send_button" onClick="send()">SEND</button>
</div>
</body>
CSS:
html,
body {
background-color: #333;
margin: 0;
padding: 0;
}
#overlay {
position: absolute;
width: 100%;
height: 100%;
opacity: 0.2;
background: #ccc;
background: -webkit-linear-gradient(right top, #8900AB, #282828);
background: -o-linear-gradient(top right, #8900AB, #282828);
background: -moz-linear-gradient(top right, #8900AB, #282828);
background: linear-gradient(to top right, #8900AB, #282828);
}
#header {
position: absolute;
background: #404040;
width: 100%;
height: 10%;
border-bottom: 10px solid #9800AB;
}
#logo {
position: absolute;
background-image: url(http://csgovoid.net/img/logo.png);
background-repeat: no-repeat;
background-size: contain;
width: 100%;
height: 100%;
}
#chat_extended {
position: absolute;
background: #404040;
margin-top: 3.15%;
width: 20%;
height: 100%;
float: right;
border-left: 10px solid #9800AB;
text-align: center;
padding-top: 5%;
}
#chat_area {
position: absolute;
background: #ccc;
width: 100%;
height: 100%;
text-align: left;
}
聊天窗口应左对齐，聊天区域位于聊天窗口内，如下所示:
最佳答案
使用 position: absolute 时不需要 float:right，只需删除它并添加 right: 0 到#chat-extended
#chat_extended {
position: absolute;
background: #404040;
width: 20%;
height: 100%;
border-left: 10px solid #9800AB;
text-align: center;
right: 0;
希望这对您有所帮助!
