On a Desktop browser, I can use the following javascript to vertically fix an element, but still allow for horizontal scroll. As you see, it re-positions the element on every scroll event. To see what I mean, try horizontally and vertically scrolling in this JSFiddle.

var verticallyFixedBox = document.getElementById('verticallyFixedBox');

window.addEventListener('scroll', function() {
    verticallyFixedBox.style.top = '' + document.body.scrollTop + 'px';
});

However, this logic fails for mobile browsers since mobile browsers apparently do not paint until an entire drag pletes, leading to a choppy experience.

What's a good way to vertically fix an element, but still allow for horizontal scrolling for mobile browsers?

• javascript

• Your fiddle doesn't seem to work for me, or at least it's not the behavior I'm expecting after reading your post. In fact, if I ment out the javascript entirely, the result doesn't change. Are you asking for a solution to having a fixed element at the top of the viewport be horizontally scrollable at any vertical scroll distance of the rest of the body? – 0dyss3us Commented Jun 12, 2015 at 18:55
• You should use document.documentElement.scrollTop instead of document.body.scrollTop, at least on Firefox. – Oriol Commented Jun 13, 2015 at 21:04

If you use a container box that is set to height: 100% and set the height of the html and body elements to 100%, then you can use position: absolute; top: 0; for the fixed header and set overflow: auto (or scroll) for the box that you want to scroll vertically.

Remember to set your body and html margins to 0 to avoid browser default styles.

I've updated the fiddle you had: http://jsfiddle/jb489ddL/1/

This solution doesn't use javascript at all so it will work on mobile browsers, since you're not relying on the scroll event.

You can do it in pure CSS.

#verticallyFixedBox {
  position: sticky;
  top: 0;
}

body {
  margin: 0;
}
#verticallyFixedBox {
  position: sticky;
  top: 0;
  background: #ccc;
  border-bottom: 2px solid #000;
  padding: 10px;
  white-space: nowrap;
}

Note not all browsers support sticky positioning yet.

Avoid using JavaScript for a layout problem. If I understand what you are looking for, you want the top-most element, verticallyFixedBox, to remain in one place, and you want its contents scrollable regardless of screen size.

Put the content of verticallyFixedBox into a separate div element. Then set that child div to be the scrollable element. You have to make sure that you fix the top, left, and right sides of verticallyFixedBox to the top, left, and right of the browser window as well.

#verticallyFixedBox
    background: #ccc;
    border-bottom: 2px solid #000;
    padding: 10px;
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
}

#scroll {
    position: relative;
    overflow: scroll;
    white-space: nowrap;
}

<div id='verticallyFixedBox'>
    <div id='scroll'>
    Lorem ipsum dolor...rest of text. 
    </div>
</div>

By fixing the outer div and scrolling inside of it, you should get a pretty consistent display across the majority of devices. Updated it on your JSFiddle Hope this is what you were looking for.

And here is an extra page with the code on a unlinked folder on my server: Test Page. It looks like it works on my phone.

You actually need JavaScript when using position:fixed; but only to implement the horizontal scrolling part. I updated my fiddle so it also provides horizontal scrolling.

What I did was keeping the verticalFixedBox with position:fixed in its place but adding onother div with the same content but opacity 0.01 and position:absolute; to retain the horizontal scrollbar.

    left: 0;
    padding: 10px;
    position: fixed;

#padder {

JavaScript:

$(window).scroll(function() {
$('#verticallyFixedBox').css({
        'left': -1 * $(this).scrollLeft()
    });
});

Only problem: opera-mini doesn't seem to support the position:fixed feature yet: http://caniuse./#feat=css-fixed
