Question

<html>
   <head>      
      <meta name="google-signin-scope" content="profile email">
      <meta name="google-signin-client_id" content="MY_CLIENT_ID_ON_GOOGLE_DEV.apps.googleusercontent.com">
      <!-- To integrate Google Sign-in -->
      <script src="https://apis.google.com/js/api.js"></script>
      <script src="https://apis.google.com/js/platform.js" async defer></script>
   </head>
   <body>
      <div class="g-signin2" data-onsuccess="onSignIn"></div>
   </body>
</html>

不显示。这个HTML代码段有什么问题？我是否必须执行其他操作才能显示Google登录按钮？

Answer 1

这是我使用materializecss提出的优雅解决方案。

Answer 4

如果您使用Bootstrap v4，则可以得到如下所示的漂亮按钮：

<div class="row">
  <div class="col-md-3">
    <a class="btn btn-outline-dark" href="/users/googleauth" role="button" style="text-transform:none">
      <img width="20px" style="margin-bottom:3px; margin-right:5px" alt="Google sign-in" src="https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Google_%22G%22_Logo.svg/512px-Google_%22G%22_Logo.svg.png" />
      Login with Google
    </a>
  </div>

如果您碰巧使用Foundation：

<div>
  <a class="hollow button primary" href="#">
    <img width="15px" style="margin-bottom:3px; margin-right:5px" alt="Google login" src="https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Google_%22G%22_Logo.svg/512px-Google_%22G%22_Logo.svg.png" />
