将 YouTube 视频缩小到响应宽度 [英] Shrink a YouTube video to responsive width

问题描述

我在我们的网站上嵌入了一个 YouTube 视频，当我将屏幕缩小到平板电脑或手机尺寸时，它在宽度约为 560 像素时停止缩小.这是 YouTube 视频的标准还是我可以添加到代码中以使其变小?

I have a YouTube video embedded on our website and when I shrink the screen to tablet or phone sizes it stops shrinking at around 560px in width. Is this standard for YouTube videos or is there something that I can add to the code to make it go smaller?

推荐答案

您可以使用 CSS 使 YouTube 视频具有响应性.使用videowrapper"类将 iframe 包裹在一个 div 中，并应用以下样式:

You can make YouTube videos responsive with CSS. Wrap the iframe in a div with the class of "videowrapper" and apply the following styles:

.videowrapper {
    float: none;
    clear: both;
    width: 100%;
    position: relative;
    padding-bottom: 56.25%;
    padding-top: 25px;
    height: 0;
}
.videowrapper iframe {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

.videowrapper div 应该在响应式元素内..videowrapper 上的填充对于防止视频崩溃是必要的.您可能需要根据您的布局调整数字.

The .videowrapper div should be inside a responsive element. The padding on the .videowrapper is necessary to keep the video from collapsing. You may have to tweak the numbers depending upon your layout.
