'The transform3d' property does not apply to fixed-positioned children

Question

'The transform3d' property does not apply to fixed-positioned children

I am facing an issue where a fixed div is not being positioned correctly when a parent element has a translate3d transform applied in CSS. I have tried various options like webkit-transform and transform-origin, but without success.

Below is a simplified example of the problem:

#outer {
    position:relative; 
    -webkit-transform:translate3d(0px, 20px , 0px); 
    height: 300px; 
    border: 1px solid #5511FF; 
    padding: 10px;
    background: rgba(100,180,250, .8); 
    width: 80%;
}
#middle{
    position:relative; 
    border: 1px dotted #445511; 
    height: 300px; 
    padding: 5px;
    background: rgba(250,10,255, .6);
}
#inner {
    position: fixed; 
    top: 0px;
    box-shadow: 3px 3px 3px #333; 
    height: 20px; 
    left: 0px;
    background: rgba(200,180,80, .8); 
    margin: 5px; 
    padding: 5px;
}

<div id="container">
    Blue: Outer, <br>
    Purple: Middle<br>
    Yellow: Inner<br>
    <div id="outer"> 
        <div id="middle">
            <div id="inner">
                Inner block
            </div>
        </div>
    </div>
</div>

How can I correct the positioning of fixed elements when using translate3d on parent elements?

Answer №1

The reason for this behavior is that the transform property establishes a new local coordinate system, as indicated in the W3C specification:

When the transform property is applied with a value other than none, it creates both a stacking context and a containing block within the HTML namespace. This results in the transformed element becoming the containing block for any fixed positioned descendants.

Consequently, elements with fixed positioning will be fixed relative to the transformed element rather than the viewport.

At present, there doesn't seem to be a workaround available for this issue.

This behavior is further detailed in Eric Meyer's article: Un-fixing Fixed Elements with CSS Transforms.

In accordance with Bradoergo's suggestion, simply retrieve the window's scrollTop value and add it to the absolute position top like so:

function adjust_scroll() {
  var scrollVal = $(window).scrollTop();
  var fixedContainer = $('#fixedContainer');
  fixedContainer.css('position','absolute');
  fixedContainer.css('top',scrollVal + 'px');
}
adjust_scroll();

$(window).on('scroll', adjust_scroll);

This method proved effective for me as well.

I experienced a flickering effect on my fixed top navigation bar when elements on the page were using transform properties. To resolve the jumping/flickering issue, I made the following adjustments to my top navigation bar:

#fixedTopNav {
    position: fixed;
    top: 0;
    transform: translateZ(0);
    -webkit-transform: translateZ(0);
}

Utilizing position: sticky; is effective in Firefox and Safari as an alternative to position: fixed;. However, this method may not be compatible with other browsers, necessitating the use of JavaScript for a universal solution.

In my perspective, the most effective approach to address this issue is to implement the same translate, but separate children that require adjustment from their parent (translated) element; and then apply the translate to a div within the position: fixed container.

The outcome will resemble something like the following (in your specific scenario):

<div style='position:relative; border: 1px solid #5511FF; 
            -webkit-transform:translate3d(0px, 20px , 0px); 
            height: 100px; width: 200px;'> 

</div>
<div style='position: fixed; top: 0px; 
            box-shadow: 3px 3px 3px #333; 
            height: 20px; left: 0px;'>
    <div style='-webkit-transform:translate3d(0px, 20px, 0px);'>
        Inner block
    </div>
</div>

While this may not be suitable for all scenarios, in most cases if you are fixing a div, you probably do not care about its parent element or position in the DOM hierarchy, and this method seems to alleviate many complications - while still maintaining harmony between translate and position: fixed.

Encountered a similar issue recently. The only variation was that the element with 'position: fixed' had its 'top' and 'left' styles set by JavaScript. To resolve this, I implemented the following solution:

var newRect = currentElement.getBoundingClientRect();

The newRect object stores the actual (relative to view port) top and left coordinates. By using this, adjustments can be made to the currentElement.style.top and currentElement.style.left properties accordingly.

My website had an off canvas sidebar using -webkit-transform: translate3d, which was causing a problem when trying to add a fixed footer. After some troubleshooting, I discovered a solution by targeting a specific class on the html page that gets added to the tag when the sidebar initializes. By using a CSS :not qualifier to set "-webkit-transform: none;" on the html tag only when that particular class is not present, I was able to resolve the issue. Hopefully this tip will be helpful for others facing the same challenge!

Experiment with applying the reverse transformation to the child element:

<div style='position:relative; border: 1px solid #5511FF; 
            -webkit-transform:translate3d(0px, 20px , 0px); 
            height: 100px; width: 200px;'> 
    <div style='position: fixed; top: 0px; 
                -webkit-transform:translate3d(-100%, 0px , 0px); 
                box-shadow: 3px 3px 3px #333;

To add a dynamic class as the element is being transformed, use the following jQuery code:

$('#elementId').addClass('transformed')

. After that, define the CSS rules below:

.translat3d(@x, @y, @z) { 
     -webkit-transform: translate3d(@X, @y, @z); 
             transform: translate3d(@x, @y, @z);
      //Include other transformations like -moz-transform, -o-transform and -ms-transform 
}

Next,

#elementId { 
      -webkit-transform: none; 
              transform: none;
}

Afterwards,

.transformed {
    #elementId { 
        .translate3d(0px, 20px, 0px);
    }
}

By using position: fixed along with values for top and z-index on a child element, you can ensure its stability even when the parent element is undergoing transformation. This is especially useful for navigation sidebars that open and close upon user interaction, or sticky tab-sets that should remain in place as users scroll down the page.

To address this issue, one possible solution is to implement the identical transformation on the fixed element as well:

<br>
<div style='position:relative; border: 1px solid #5511FF; 
            -webkit-transform:translate3d(0px, 20px , 0px); 
            height: 100px; width: 200px;'> 
    <div style='position: fixed; top: 0px; 
                -webkit-transform:translate3d(0px, 20px , 0px); 
                box-shadow: 3px 3px 3px #333; 
                height: 20px; left: 0px;'>
        Content inside
    </div>
