在 div 中居中 div
Center a div inside a div
我的 HTML 代码有问题我想将 division 内的东西居中,而 division 内。我不太确定如何。这是我的代码:
HTML 代码(实际上是一个 PHP 文件):
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="mateo.css">
<title>Mateo's About Page</title>
</head>
<body>
<div class="items">
<div id="basicInfo">
<img src="images/question.png">
</div>
<div id="langs">
<img src="images/code.jpg">
</div>
</div>
<div id="textSpace">
</div>
<?php
$username = $_POST['username'];
$password = $_POST['password'];
$accounts = mysqli_connect("localhost","root","BKpH7e6k","accounts") or die(mysqli_error());
mysqli_select_db($accounts, "accounts");
$sql = "
SELECT * from users WHERE Username LIKE '{$username}' AND Password LIKE '{$password}' LIMIT 1
";
$results = $accounts->query($sql);
if(!$results->num_rows == 1){
header("Location: http://localhost/aboutPage/login.php");
} else {
echo "<p>Logged in successfully!</p>";
}
?>
</body>
</html>
这是我的 css 文件:
body {
background: url("images/background.jpg") repeat;
font-size: 100%;
font-family: Arial;
}
.items {
display: block;
background-color: gray;
max-width: 50%;
max-height: 100%;
border-radius: 20px;
border: 2px solid black;
opacity: .8;
margin-left: auto;
margin-right: auto;
}
#basicInfo{
background-color: orange;
width: 100px;
height: 100px;
display: inline-block;
margin-top: 10px;
margin-bottom: 10px;
}
#basicInfo:hover{
background-color: green;
}
#basicInfo img{
display: block;
margin-left: auto;
margin-right: auto;
padding-top: 16px;
}
#langs{
background-color: orange;
width: 100px;
height: 100px;
display: inline-block;
margin-top: 10px;
margin-bottom: 10px;
}
#langs img{
display: block;
margin-left: auto;
margin-right: auto;
padding-top: 16px;
}
#langs:hover{
background-color: green;
}
而这是一张图片或问题。
所以我希望橙色框在它们所在的 div 中心彼此相邻浮动。任何帮助都适用 :) 谢谢 1
由于您在 #basicInfo
和 #langs
上使用 display: inline-block
,只需在父级 .items
上调用 text-align: center
:
.items {
display: block;
background-color: gray;
max-width: 50%;
max-height: 100%;
border-radius: 20px;
border: 2px solid black;
opacity: .8;
margin-left: auto;
margin-right: auto;
text-align: center; //add
}
将 text-align: center 添加到您的 .items class (http://jsfiddle.net/cz19q7a9/)
.items
{
text-align: center;
}
只需在div
里面做margin: auto
,它就会根据它的父级居中。 Here is an example.
