页面
推荐答案
摆脱所有行
和 col
类,将登录框放在占用整个屏幕的 flex
容器中( h-100
),然后使用 m-auto
设置边距:
Get rid of all the row
and col
classes, drop the login box in a flex
container that takes up the entire screen (h-100
), and set the margins using m-auto
:
html, body { height: 100%; }
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet" />
<!-- flex container -->
<div class="d-flex h-100">
<!-- login box -->
<div class="m-auto">
<form method="post" action="">
<div class="form-group">
<h2 class="login-header">Login</h2>
</div>
<div class="form-group">
<input type="text" name="username" placeholder="Username" class="username-input">
</div>
<div class="form-group">
<input type="password" name="password" placeholder="Password" class="password-input">
</div>
<div class="form-group">
<input type="checkbox" name="remember"><span>Remember Me Next Time</span>
</div>
<div class="form-group">
<input type="submit" name="login-button" value="GO" class="submit-button">
</div>
</form>
</div>
