Background images are a very important element in web design, which can increase the beauty and appeal of the web page. It is very easy to set a background image in HTML. This article will introduce how to set an HTML background image.

Step one: Prepare the picture

First prepare a picture suitable as a background. The size of the picture should not be too large. Pictures that are too large will cause the web page to open slowly. At the same time, you need to pay attention to whether the resolution, color and pattern of the picture are consistent with the web design style.

Step 2: HTML code setting

Setting the background image in the HTML code requires the use of CSS styles. Here is an example:

<!DOCTYPE html>
<html>
<head>
    <title>设置背景图片HTML</title>
    <style type="text/css">
        body {
            background-image: url(your-image-path.jpg);
            background-repeat: no-repeat;
            background-size: cover;
            background-position: center center;
            background-attachment: fixed;
        }
    </style>
</head>
<body>
    <!-- 网页主体内容 -->
</body>
</html>

In the above code, we use the body tag to set the background image. background-image: url(your-image-path.jpg) Used to set the path of the background image, background-repeat: no-repeat means that the background image does not repeat, background-size: cover means that the background image fills the entire screen as much as possible, background-position: center center means that the background image is displayed in the center of the web page, background-attachment: fixed Indicates that the background image is fixed.

It is worth noting that the value of background-image can be a relative path or an absolute path. If it is a relative path, it needs to be set according to your folder structure. At the same time, the value of background-attachment can also be scroll, which means that the background image will move as the document scrolls.

Step 3: Other settings

In addition to the above settings, we can also make other settings for the background image. For example, you can set translucency to make the background image less obtrusive, set a background color to blend in with the background image, and more. Here are some examples:

<style type="text/css">
    body {
        background-image: url(your-image-path.jpg);
        background-repeat: no-repeat;
        background-size: cover;
        background-position: center center;
        background-attachment: fixed;
        background-color: rgba(255, 255, 255, 0.5);
    }
</style>

Copy after login

In the above example, we added background-color: rgba(255, 255, 255, 0.5) to set the color of the background image to semi-transparent white .
