HTML prohibits sliding - how to implement it?

In web design and development, sliding is an important interaction method. However, in some cases, we want to prohibit web page sliding. This requirement is often seen in the following scenarios:

1. When a web page pops up, we do not want users to view the web page content by sliding;
2. In some special application scenarios, users need to be prohibited from sliding the page.

So, how to prevent sliding in HTML? This article will introduce two methods to you.

Method 1: Use CSS properties

In the CSS file, we can use the following statement to prohibit sliding:

body{
   overflow: hidden;
}

This CSS code hides the scroll bar of the page, This achieves the effect of prohibiting sliding. This method is suitable for situations where a fixed-size window needs to pop up in the middle of the page to prohibit users from continuing to slide and browse.

However, this method also has some shortcomings. It only hides the scroll bar, but does not prohibit the user from scrolling the page. If the user uses the keyboard or mouse wheel to slide, problems will still occur.

Method 2: Using JavaScript code

In addition to using CSS properties, we can also use JavaScript code to prevent HTML from sliding.

var scrollTop;
function stopScroll(){
    scrollTop = document.body.scrollTop || document.documentElement.scrollTop;
    document.body.style.overflow='hidden';
    document.body.style.position='fixed';
    document.body.style.top=-scrollTop+'px';
}
function allowScroll(){
    document.body.style.overflow='auto';
    document.body.style.position='';
    document.body.style.top='';
    document.body.scrollTop = scrollTop;
    document.documentElement.scrollTop = scrollTop;
}

The above code defines two functions stopScroll() and allowScroll(), which are used to stop and allow page sliding respectively. Among them, the stopScroll() function is used to prohibit page scrolling, and the allowScroll() function is used to restore the page scrolling function.

This method can completely prohibit the user from sliding on the page, and also ensures that the user's sliding position is restored before the page is loaded.

However, please note that this method may not be suitable for all application scenarios and browsers. Some browsers may not fully support JavaScript, causing this code to not work properly.

Conclusion

HTML prohibiting sliding is a common web design requirement. This article explains two different methods, using CSS properties and JavaScript code. Readers can choose a suitable method to prohibit page sliding according to actual needs; at the same time, they should also pay attention to the limitations of the method and the compatibility of the browser.
