Question

我正在使用引导程序4，我的导航栏具有注册和登录按钮。我在按钮之间使用了填充以留出空间，在所有屏幕上都很好，但在小屏幕上填充不可见，如此处所示。

这是我的页面html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>Register form</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <script src="http://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>

 <body>

Answer 1

您只需要使用py-1而不是所有其他其他最底层的类...

        <ul class="nav navbar-nav mx-auto">
            <li class="nav-item pl-lg-1 pr-lg-1 py-1">
                <a class="btn btn-sm align-middle btn-primary custom-btn" href="#">Log in</a>
            </li>
            <li class="nav-item pl-lg-1 pr-lg-1 py-1">
                <a class="btn btn-sm align-middle btn-success" href="#">Sign up</a>
            </li>
        </ul>
