Flexbox 是一款功能強大的佈局工具，可輕鬆地將元素水平和垂直居中。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Center Div with Flexbox</title>
<style>
.container {
display: flex;
justify-content: center; /* Horizontal center */
align-items: center; /* Vertical center */
height: 100vh; /* Full viewport height */
}
.centered-div {
width: 200px;
height: 200px;
background-color: lightblue;
}
</style>
</head>
<body>
<div class="container">
<div class="centered-div">Centered with Flexbox</div>
</div>
</body>
</html>
CSS Grid 是另一個強大的佈局系統，可以輕鬆地將元素居中。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Center Div with Grid</title>
<style>
.container {
display: grid;
place-items: center; /* Center both horizontally and vertically */
height: 100vh; /* Full viewport height */
}
.centered-div {
width: 200px;
height: 200px;
background-color: lightcoral;
}
</style>
</head>
<body>
<div class="container">
<div class="centered-div">Centered with Grid</div>
</div>
</body>
</html>
此方法涉及絕對定位 div 並使用變換將其居中。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Center Div with Absolute Positioning</title>
<style>
.container {
position: relative;
height: 100vh; /* Full viewport height */
}
.centered-div {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 200px;
height: 200px;
background-color: lightgreen;
}
</style>
</head>
<body>
<div class="container">
<div class="centered-div">Centered with Absolute Positioning</div>
</div>
</body>
</html>
對指定寬度的元素設定 margin: auto 可以使其水平居中。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Center Div with Margin Auto</title>
<style>
.container {
width: 100%;
height: 100vh; /* Full viewport height */
display: flex;
align-items: center; /* Vertical center */
}
.centered-div {
margin: 0 auto; /* Horizontal center */
width: 200px;
height: 200px;
background-color: lightcoral;
}
</style>
</head>
<body>
<div class="container">
<div class="centered-div">Centered with Margin Auto</div>
</div>
</body>
</html>
此方法使用 display: table 和 display: table-cell 將元素置中。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Center Div with Table Display</title>
<style>
.container {
display: table;
width: 100%;
height: 100vh; /* Full viewport height */
}
.centered-div {
display: table-cell;
vertical-align: middle; /* Vertical center */
text-align: center; /* Horizontal center */
}
.inner-div {
display: inline-block;
width: 200px;
height: 200px;
background-color: lightpink;
}
</style>
</head>
<body>
<div class="container">
<div class="centered-div">
<div class="inner-div">Centered with Table Display</div>
</div>
</div>
</body>
</html>
