Why does a fixed background-image move when scrolling on IE?

问题

I'm trying to make background-image fixed.

As you see in my blog, the background-image is moving when scrolling on IE 11.

How can I fix this?

This is my CSS:

background-image: url("./images/cover.jpg");
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
background-size: cover;

回答1:

This is a known bug with fixed background images in Internet Explorer. We recently did some work to improve this behavior and have shipped updates to our preview build of Internet Explorer on Windows 10. You can test the changes today from Mac OS X or Windows on http://remote.modern.ie.

Below is the before and after, IE 11 and IE Remote Preview. Notice how scrolling with the mouse-wheel no longer causes the fixed background image to jump (or jitter) as it did in Internet Explorer 11.

My final fix is based on all the answers I've found:

On the main css for Edge / ie11 / ie10

/*Edge*/
@supports ( -ms-accelerator:true ) 
{
    html{
        overflow: hidden;
        height: 100%;    
    }
    body{
        overflow: auto;
        height: 100%;
    }
}
/*Ie 10/11*/
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) 
{
    html{
        overflow: hidden;
        height: 100%;    
    }
    body{
        overflow: auto;
        height: 100%;
    }
}

For ie9, ie8 and ie7 I've added the code (without media query) in a separate hacksheet:

<!--[if lte IE 9]>
    <style type=text/css>
       html{
           overflow: hidden;
           height: 100%;    
       }
       body{
           overflow: auto;
           height: 100%;
       }
    </style>
<![endif]-->

I have tried to disable some of css rules on your site and when I remove background property (background:#fff;) for html tag then page is scrolling smoothly. Please, try it and tell if it works for you.

Update:

I have also found workaround here:

$('body').on("mousewheel", function () {
  event.preventDefault();

  var wheelDelta = event.wheelDelta;

  var currentScrollPosition = window.pageYOffset;
  window.scrollTo(0, currentScrollPosition - wheelDelta);
});

回答4:

This seems to be working on trackpads for me. It builds on radarek's workaround.

    if(navigator.userAgent.match(/Trident\/7\./)) {
    $('body').on("mousewheel", function () {
        event.preventDefault();

        var wheelDelta = event.wheelDelta;

        var currentScrollPosition = window.pageYOffset;
        window.scrollTo(0, currentScrollPosition - wheelDelta);
    });

    $('body').keydown(function (e) {
        e.preventDefault(); // prevent the default action (scroll / move caret)
        var currentScrollPosition = window.pageYOffset;

        switch (e.which) {

            case 38: // up
                window.scrollTo(0, currentScrollPosition - 120);
                break;

            case 40: // down
                window.scrollTo(0, currentScrollPosition + 120);
                break;

            default: return; // exit this handler for other keys
        } 
    });
}

For latest edge release use this, as prior answer by twicejr no longer works:

/*Edge - works to 41.16299.402.0*/
@supports (-ms-ime-align:auto) 
{
    html{
        overflow: hidden;
        height: 100%;       
    }
    body{
        overflow: auto;
        height: 100%;
        position: relative;
    }
}

/*Ie 10/11*/
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) 
{
    html{
        overflow: hidden;
        height: 100%;    
    }
    body{
        overflow: auto;
        height: 100%;
    }
}

回答6:

Target IE and using scroll instead appears to fix the issue.

@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
    .className {
        background-attachment: scroll;
    }
}

回答7:

I just came across a case where I was able to reduce the stuttering by removing box-shadow from elements that overlap the fixed background.

回答8:

The previous answer fixed my issue in IE11! However, I had to make a small change so it will also let me refresh the page using F5 (or Ctrl+F5):

//In IE 11 this fixes the issue when scrolling over a photo break without using the scroll bar

 if(navigator.userAgent.match(/Trident\/7\./)) {
    $('body').on("mousewheel", function () {
        event.preventDefault();

        var wheelDelta = event.wheelDelta;

        var currentScrollPosition = window.pageYOffset;
        window.scrollTo(0, currentScrollPosition - wheelDelta);
    });

    $('body').keydown(function (e) {

        var currentScrollPosition = window.pageYOffset;

        switch (e.which) {

            case 38: // up
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition - 120);
                break;

            case 40: // down
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition + 120);
                break;

            default: return; // exit this handler for other keys
        } 
    });
}

Using this script: https://stackoverflow.com/a/34073019/7958220

To detect the edge browser, I then changed the style for html and body.

if (document.documentMode || /Edge/.test(navigator.userAgent)) {
   document.documentElement.style.overflow = "hidden";
   document.documentElement.style.height = "100%";
   document.body.style.overflow = "auto";
   document.body.style.height = "100%"; 

}

回答10:

I tried twicejr's CSS solution but it is not working in Edge/15.15063. Dasha's answer solved the problem in Edge but not IE 11. I noticed that the document.documentMode condition was not complete. document.documentmode will return undefined for all browsers except for IE 8+ which will return the mode number. With that, the following code will detect both IE 8+ and Edge and solve the background image problem.

if ((document.documentMode != undefined) || (/Edge/.test(navigator.userAgent))) {
document.documentElement.style.overflow = "hidden";
document.documentElement.style.height = "100%";
document.body.style.overflow = "auto";
document.body.style.height = "100%";}

JS Fiddle for the above code. This also works with arrow key and track-pad scrolling. I didn't give any consideration to IE7-

Here is a way to handle PageUP and PageDOWN keyS based on the previous answers :

if(navigator.userAgent.match(/Trident\/7\./)) { // if IE
    $('body').on("mousewheel", function () {
        // remove default behavior
        event.preventDefault(); 

        //scroll without smoothing
        var wheelDelta = event.wheelDelta;
        var currentScrollPosition = window.pageYOffset;
        window.scrollTo(0, currentScrollPosition - wheelDelta);
    });
    $('body').keydown(function (e) {
        var currentScrollPosition = window.pageYOffset;

        switch (e.which) {
            case 33: // page up
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition - 600);
                break;
            case 34: // page down
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition + 600);
                break;
            case 38: // up
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition - 120);
                break;
            case 40: // down
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition + 120);
                break;
            default: return; // exit this handler for other keys
        } 
    });

}
