How to use CSS to achieve smooth scrolling to the anchor position

In web design, the anchor position refers to a specific position on the page. When the user clicks on the page When linked, the page will smoothly scroll to that location. This effect not only brings a good user experience, but also improves the beauty of the page. This article will introduce how to use CSS to achieve smooth scrolling to the anchor point position, and give specific code examples.

1. HTML structure

First, we need to set anchor points in HTML. Add an id attribute to the position where smooth scrolling is required as the identifier of the anchor point. For example:

In the code, we have created two anchor positions, which are set to section1 and section2 using the id attribute.

2. CSS Style

Next, we need to set the CSS style to achieve a smooth scrolling effect. First, we will add a scrolling behavior transition to the body element. In CSS, we can use the scroll-behavior attribute to set the scrolling behavior to smooth scrolling. The code is as follows:

body { scroll-behavior: smooth; }

In this way, when we click the anchor link, the page will scroll smoothly to the target position.

3. Add anchor link

In order to smoothly scroll to the anchor position, we need to add an anchor link to the page. Where you need to scroll to, such as a navigation menu or other link location, use an a tag to create a link, and set the link's href attribute to the ID of the anchor location. For example:

跳转到Section 1 跳转到Section 2

In this way, when the user clicks on the link, the page will scroll smoothly to the corresponding anchor position.

4. Compatibility considerations

Although the above method can work normally in most modern browsers, the scroll-behavior attribute may not be supported in some older versions of browsers. To ensure it works properly in all browsers, we can use JavaScript to achieve a smooth scrolling effect.

// JavaScript代码示例 $('a[href*="#"]').on('click', function(e){ e.preventDefault(); $('html, body').animate( { scrollTop: $($(this).attr('href')).offset().top, }, 800, 'linear' ); });

This code will use animation effects to smoothly scroll to the anchor position when the anchor link is clicked. It should be noted that the jQuery library needs to be introduced to achieve this effect.

Summary

Through the scroll-behavior property of CSS, we can easily achieve a smooth scrolling effect. Of course, in order to ensure that it works properly on different browsers, we can also use JavaScript to achieve this effect. Whether it is CSS or JavaScript, the smooth scrolling effect can enhance the user experience and make web pages smoother and more beautiful. Applying this technology to web design can improve the quality and user evaluation of the website.
