CSS Filter Invert Rule Breaking Fixed Position on Chrome 68

CSS Filter invert rule breaking fixed position on Chrome 68

It looks like a bug on Google Chrome 68, but you can solve this using the <html> element instead of the <body> element:

html {  height: 8000px;  filter: invert(0.85);}div {  position: fixed;  top: 0;  left: 0;  bottom: 0;  height: 100px;  width: 100px;  border: 1px solid black;}

<div></div>

Why does applying a CSS-Filter on the parent break the child positioning?

If we refer to the specification we can read:

A value other than none for the filter property results in the
creation of a containing block for absolute and fixed positioned
descendants unless the element it applies to is a document root
element in the current browsing context. The list of functions are
applied in the order provided.

This means that your position:fixed element will be positioned relatively to the filtered container and no more the viewport. In other words, it's still fixed but inside its new containing block (the filtered container)

Here is a simplified version to illustrate the issue:

.container {
  display: inline-block;
  width: 200px;
  height: 200vh;
  border: 1px solid;
}

.container>div {
  position: fixed;
  width: 100px;
  height: 100px;
  background: red;
  color: #fff;
}

<div class="container">
  <div>I am fixed on scroll</div>
</div>

<div class="container" style="filter:grayscale(1);">
  <div>I move with the scroll</div>
</div>

From Understanding CSS Filter Effects:

When a browser loads a web page it needs to apply styles, perform layout and then render the page so there's something to look at. Filters kick in after all those steps and just before the page is copied to the screen. What they do is take a snapshot of the rendered page as a bitmap image, then perform some graphics magic on the pixels in the snapshot and then draw the result over the top of the original page image.

You're applying a filter to the body, and the filter is applied to the whole element as a flattened image, not each child element individually, so you can't override the filter on a child like you're trying to do.

What you can do in your case is apply invert(100%) to the selector you want to show up as uninverted, because a double inverted image becomes normal again.

Table fixed header and scrollable body

Here is the working solution:

table {    width: 100%;}
thead, tbody, tr, td, th { display: block; }
tr:after {    content: ' ';    display: block;    visibility: hidden;    clear: both;}
thead th {    height: 30px;
    /*text-align: left;*/}
tbody {    height: 120px;    overflow-y: auto;}
thead {    /* fallback */}

tbody td, thead th {    width: 19.2%;    float: left;}

<table class="table table-striped">    <thead>        <tr>            <th>Make</th>            <th>Model</th>            <th>Color</th>            <th>Year</th>        </tr>    </thead>    <tbody>        <tr>            <td class="filterable-cell">Ford</td>            <td class="filterable-cell">Escort</td>            <td class="filterable-cell">Blue</td>            <td class="filterable-cell">2000</td>        </tr>        <tr>            <td class="filterable-cell">Ford</td>            <td class="filterable-cell">Escort</td>            <td class="filterable-cell">Blue</td>            <td class="filterable-cell">2000</td>        </tr>        <tr>            <td class="filterable-cell">Ford</td>            <td class="filterable-cell">Escort</td>            <td class="filterable-cell">Blue</td>            <td class="filterable-cell">2000</td>        </tr>        <tr>            <td class="filterable-cell">Ford</td>            <td class="filterable-cell">Escort</td>            <td class="filterable-cell">Blue</td>            <td class="filterable-cell">2000</td>        </tr>    </tbody></table>
