所以这要么是 CSS 问题，要么是 Javascript，但我需要你的专业知识。
我有一个网站，上面有 youtube API。
YouTube API 要求您授权自己开始拉取。
授权前看起来像这样：http: //d.pr/i/96sB
一旦您授权，该框就会消失：http ://d.pr/i/4SVx
这是相关的javascript：
// gapi.auth.authorize() call.
function handleAuthResult(authResult) {
if (authResult) {
$('.pre-auth').hide();
loadAPIClientInterfaces();
} else {
$('#login-link').click(function() {
gapi.auth.authorize({
client_id: OAUTH2_CLIENT_ID,
scope: OAUTH2_SCOPES,
immediate: false
}, handleAuthResult);
});
}
}
HTML
<div id="login-container" class="pre-auth back_image">Please click <a href="#" id="login-link">this link</a> to load the playlist. It will pull authorization for the API from your Google account
<img src="Pictures/AuthButtons.jpg" width="1060" height="20">
</div>
CSS
.wrap{

margin: auto;
}
.back_image{
width: 1060px;

margin: auto;
text-align:center;

}
iframe{
margin: auto;
}
.background_color{
background-color: #F8F8F8;
}
h1{
}
.paging-button {
visibility: hidden;
}
.video-content {
width: 200px;
height: 200px;
background-position: center;
background-repeat: no-repeat;
float: left;
position: relative;
margin: 5px;
}
.video-title {
width: 100%;
text-align: center;
background-color: rgba(0, 0, 0, .3);
color: white;
top: 50%;
left: 50%;
position: absolute;
-moz-transform: translate(-50%, -50%);
-webkit-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
}
.video-content:nth-child(3n+1) {
clear: both;
}
.button-container {
clear: both;
}
#video-container a {
float: left;
}
#video-container{
width: 100%;
}
底部将是整个页面的 HTML/Java 来绘制完整的图片。
我希望保留该框，以便保留授权消息，但是一旦授权，请让它说出“单击以欣赏任何 htese 视频”或其他内容的内容
有任何想法吗？
这是整个页面：
