YouTube API 以 5 x 3 网格而不是单列列表列出播放列表图标
YouTube API listing playlist icons in 5 x 3 grid instead of single column list
下面是我的代码... Javascript和JQuery在头脑中，但CSS是一个外部文档。
还有一个额外的片段，其中包含一个存储名称的cookie...忽略它...
它是YouTube的API，用于提取我最近的上传。 一切都很好，除了我最终在一列中有一个 15 个视频播放列表，而且我一直无法弄清楚如何让它分类成任何类型的网格排列（5 x 3 或其他）。 播放列表中加载的视频数量可以调整为 5x3、4x3，无论 x 什么都可以工作。
在这里实时查看此页面： 98.255.116.178
有什么想法或指导可以让这些视频进入网格排列吗？

当然，CSS：
.wrap{
width: 1000px;
margin: auto;
text-align: center;
}
.background_color{
background-color: #AABF94;
}
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, .5);
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;

这
似乎对我有用。

你的CSS变成了：

margin: auto;
text-align: center;
}
.background_color{
background-color: #AABF94;
}
h1{
}
.paging-button {

}
.box_wrapper {
margin: 0;
height: 100%;
width: 1000px;
overflow: hidden;
}
.video_select {
float: left;
display: table-cell;

.video-content {
width: 200px;
height: 200px;
background-position: center;
background-repeat: no-repeat;
float: left;
position: relative;
margin: 5px;
display: table-cell;

.video-title {
width: 100%;
text-align: center;
background-color: rgba(0, 0, 0, .5);
color: white;
top: 50%;

transform: translate(-50%, -50%);
}
.video-content:nth-child(3n+1) {
clear: both;
}
.button-container {
clear: both;
}
这与修复无关，但我清理了一下 HTML：
<div class="wrap">
<h1 id="title_script">Welcome to my Sandbox</h1>
<div class="wrap">
<iframe id='youTube_video' width="853" height="480" src="//www.youtube.com/embed/io78hmjAWHw?autoplay=1" frameborder="0" allowfullscreen></iframe>
</div>
<div id="login-container" class="pre-auth">Please click <a href="#" id="login-link">authorize</a> to continue.

<div id="video-container">
</div>
<div class="button-container">
<button id="prev-button" class="paging-button" onclick="previousPage();">Previous Page</button>
<button id="next-button" class="paging-button" onclick="nextPage();">Next Page</button>
</div>
</div>
<script src="https://apis.google.com/js/client.js?onload=googleApiClientReady"></script>
在 CSS 中，将换行从宽度 1000 更改为 1060，并添加了以下两行：
#video-container a {
float: left;
}
#video-container{
width: 100%;
}
