With the popularity of mobile device use, responsive design has become essential in modern web design a part of. In this article, we will learn how to create a responsive video display layout using HTML and CSS. This layout will adapt to different screen sizes and display well on any device.

Step 1: HTML structure

First, we need to create a basic HTML structure. Add a div element to the body tag as a container for the entire layout. In this container we will include the video and its related content. The HTML code looks like this:

<!DOCTYPE html>
<html>
<head>
  <title>响应式视频展示布局</title>
  <style>
    /* CSS样式将在下一步中添加 */
  </style>
</head>
<body>
  <div class="container">
    <div class="video">
      <iframe src="https://www.youtube.com/embed/xxxxxxxxxx" frameborder="0" allowfullscreen></iframe>
    </div>
    <div class="details">
      <h2>视频标题</h2>
      <p>视频描述</p>
    </div>
  </div>
</body>
</html>

Step 2: CSS Styles

Now, we need to add some CSS styles to create our responsive layout. We will use Flexbox layout and media queries to achieve adaptive effects. The CSS code is as follows:

.container {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
  align-items: center;
}

.video {
  flex-basis: 100%;
}

.details {
  flex-basis: 100%;
  text-align: center;
}

@media screen and (min-width: 600px) {
  .video {
    flex-basis: 50%;
  }

  .details {
    flex-basis: 50%;
    text-align: left;
  }
}

In the above code, we first set the display property of .container to flex to use Flexbox layout in the container. Then, we use the flex-wrap property to place the flex items on the same line and wrap them automatically. We also center the content horizontally and vertically using the justify-content and align-items properties.

Next, we define the styles of .video and .details. We use the flex-basis property to set the initial size of the items in the container. By default, we want the video and related details to take up the entire width of the container.

Finally, we use media queries to define layout on larger screens. When the screen width is greater than or equal to 600px, we set the video and detail parts to 50% width respectively, and set the text alignment of the detail part to left alignment.

Step Three: Make the Video Container Responsive

In the above code, we just added the video as an iframe element. In order for the video container to display properly and be responsive, we need to add some CSS styles. The CSS code is as follows:

.video iframe {
  display: block;
  width: 100%;
  height: auto;
}

In the above code, we first set the display attribute of the iframe to block to make it a block-level element. Then, we use the width attribute to set the video width to 100%. Since the height of the iframe element automatically adjusts based on the content, we can set its height to auto to keep the aspect ratio unchanged.

Conclusion

Through the above steps, we have successfully created a responsive video display layout. No matter what device the user uses to access the web page, the layout automatically adapts to the screen size. I hope this article helped you understand how to create a responsive layout using HTML and CSS.
