In web design, the selection and setting of background images is a very important part. Through the clever use of background images, the website can be made more vivid and attractive. HTML5 is a new web standard that introduces many new tags and features, including background image settings. This article will introduce how to set a background image in HTML5, as well as some practical tips and suggestions.

1. How to set the background image

1. Use CSS style sheet

In HTML5, you can set the background image through CSS style sheet. The code is as follows:

body {
    background-image:url("example.jpg");
}

Copy after login

This example uses a CSS style sheet to set the background image of the page, where "url" points to the path of the image. Note that this path is relative to the HTML file. If the image file and HTML file are in the same directory, you can write the file name directly; if they are not in the same directory, you need to write the complete path.

In addition to the "body" tag, you can also use similar methods to set background images on other tags. For example:

div {
    background-image:url("example.jpg");
}

Copy after login

This will set the background image of a div tag to "example.jpg".

2. Use HTML tags

In addition to CSS style sheets, you can also use HTML tags to set background images. HTML5 provides a "background" attribute that can be used to set the background image of a page or element. For example:

<body background="example.jpg">

Copy after login

This example sets the background of the page to "example.jpg".

Similarly, you can use this attribute on other HTML tags, for example:

<div background="example.jpg"></div>

Copy after login

This example sets the background of a div tag to "example.jpg".

It is recommended to use CSS style sheet to set the background image. Because this is more flexible, you can set different background images for different elements, and you can use other CSS properties to control the display effect of the background image. Moreover, background images can be easily applied to the entire website using CSS.

2. Practical skills for background images

1. Compress images

Using compressed images is a good practical skill. Because large-sized images will slow down the loading speed of web pages and affect the user experience. You can use online image compression tools such as TinyPNG or CompressJPEG to reduce image size to the minimum. This not only improves page loading speed but also saves bandwidth.

2. Choose high-quality pictures

Another practical tip is to choose high-quality pictures. While compressed images can help save bandwidth and increase speed, low-quality images can impact the user experience. Therefore, choose high-quality images to display. You can use professional image libraries, such as Shutterstock or iStockphoto, to get high-quality images.

3. Use patterns or tiles

Patterns or tiles are another practical trick that can give your website a unique background effect. These patterns can be simple geometric shapes or visually impactful works of art. Using patterns or tiles can give your website visual appeal and make it easy to achieve a consistent effect across browsers.

4. Pay attention to the relationship between pictures and content

The last practical tip is to pay attention to the relationship between background pictures and content. Background images should match the theme of the website and should not interfere with the presentation of content. For example, when using a picture in the background of text, the picture should be soft and blurry, not noisy or overly bright. This can make the website easier to read while improving the user experience.

3. Summary

HTML5 provides new tags and functions for background image settings, making the settings easier and more flexible. When setting up background images, you should consider compressing and selecting high-quality images, using patterns or tiles, and paying attention to the relationship between the image and the content. Through these practical tips, you can bring better visual effects to your website and improve user experience.
