html background does not repeat

How to prevent HTML background from repeating?

HTML (Hypertext Markup Language) is the most basic language in web development. It controls the structure and content of web pages through markup language. In web development, background design is very important, it can bring visual enjoyment to users and make the website more attractive. However, sometimes we find that the background of the web page is repeated, which is very detrimental to the visual experience. So, how to prevent HTML background from repeating? This article will give you detailed answers.

1. Use the background-repeat attribute

When the size of the background image is not enough, duplication often occurs. At this point, we can control how the background image repeats by setting the background-repeat attribute. The background-repeat attribute has four attribute values:

(1) repeat: default value, the background image will repeat horizontally and vertically;
(2) repeat-x: the background image will only appear in Repeat in the horizontal direction, not in the vertical direction;
(3) repeat-y: The background image only repeats in the vertical direction, not in the horizontal direction;
(4) no-repeat: The background image does not repeat at all.

By setting the value of the background-repeat attribute to no-repeat, you can prevent the HTML background from repeating.

html {
background-image:url("background.jpg");
background-repeat:no-repeat;
}

2. Use background -size attribute

If the image is too small, but we don’t want the background image to stretch and deform, but want it to be centered and fill the entire screen, we can use the background-size attribute. The background-size attribute has two optional values:

(1) cover: The background image is scaled proportionally to ensure that the image completely covers the entire container, but part of the image may be cropped.
(2) contain: The background image is scaled proportionally to ensure that the image is completely displayed inside the container.

html {
background-image:url("background.jpg");
background-size:cover;
background-repeat:no-repeat;
}

3. Use the background-attachment attribute

If the background image is large and we want the user to be able to see it all the time when scrolling the page, then we can use the background-attachment attribute. The background-attachment attribute has two values:

(1) scroll: default value, the background image will move with the content when scrolling;
(2) fixed: the background image does not move with scrolling.

html {
background-image:url("background.jpg");
background-repeat:no-repeat;
background-attachment:fixed;
}

Summary

So far, we have introduced three methods to make the HTML background non-repeating. Of course, we can also use other methods to achieve non-repeating backgrounds. For example, use the CSS3 background-clip property to position the background image to a corner of the container so that it fills the entire container without duplication. In short, no matter which method is used, we can make our web pages more beautiful and professional, and bring a better experience to users.
