kill-sticky

A bookmarklet to remove sticky elements and restore scrolling to web pages!

Demo

Background

Alisdair McDiarmid wrote at his Kill sticky headers bookmarklet page...

I hate sticky headers. I want to kill sticky headers.

I could not agree more.

But, while McDiarmid's code has already been immensely helpful to me, I wanted to extend it to also kill of another recent trend: marketing modals. They also abuse position: fixed styling and remove your ability to scroll with overflow: hidden. Not cool, man.

And that's what this extension aims to address:

Delete fixed position styled elements
Change hidden overflow styles to auto

Installation

Make a new bookmark (on your bookmark bar) with the following URL:

javascript:(function()%7Bdocument.querySelectorAll(%22body%20*%22).forEach(function(node)%7Bif(%5B%22fixed%22%2C%22sticky%22%5D.includes(getComputedStyle(node).position))%7Bnode.parentNode.removeChild(node)%7D%7D)%3Bdocument.querySelectorAll(%22html%20*%22).forEach(function(node)%7Bvar%20s%3DgetComputedStyle(node)%3Bif(%22hidden%22%3D%3D%3Ds%5B%22overflow%22%5D)%7Bnode.style%5B%22overflow%22%5D%3D%22visible%22%7Dif(%22hidden%22%3D%3D%3Ds%5B%22overflow-x%22%5D)%7Bnode.style%5B%22overflow-x%22%5D%3D%22visible%22%7Dif(%22hidden%22%3D%3D%3Ds%5B%22overflow-y%22%5D)%7Bnode.style%5B%22overflow-y%22%5D%3D%22visible%22%7D%7D)%3Bvar%20htmlNode%3Ddocument.querySelector(%22html%22)%3BhtmlNode.style%5B%22overflow%22%5D%3D%22visible%22%3BhtmlNode.style%5B%22overflow-x%22%5D%3D%22visible%22%3BhtmlNode.style%5B%22overflow-y%22%5D%3D%22visible%22%7D)()%3B%0A

Usage

Every time you see a bothersome fixed position element and/or loss of scrolling functionality, click the bookmark!

This may break the page sometimes, such as deleting nav or causing scrollbars to show up where they shouldn't. If that happens, just reload the page.

How the bookmarklet works

Iterate through all child nodes of body. Delete the node if it is styled with position: fixed.
Set the style of the html node for overflow: auto.

    document.querySelectorAll('body *').forEach(function(node) {
        if (['fixed', 'sticky'].includes(getComputedStyle(node).position))  {
            node.parentNode.removeChild(node);
        }
    });

    document.querySelectorAll('html *').forEach(function(node) {
        var s = getComputedStyle(node);
        if ('hidden' === s['overflow']) { node.style['overflow'] = 'visible'; }
        if ('hidden' === s['overflow-x']) { node.style['overflow-x'] = 'visible'; }
        if ('hidden' === s['overflow-y']) { node.style['overflow-y'] = 'visible'; }
    });

    var htmlNode = document.querySelector('html');
    htmlNode.style['overflow'] = 'visible';
    htmlNode.style['overflow-x'] = 'visible';
    htmlNode.style['overflow-y'] = 'visible';

Building (Only if you want to contribute)

We're creating a bookmarklet, so our code needs to be minified and URL encoded.

Run the following the project root directory:

$ docker build . -t kill-sticky && docker run --rm -it -v $(pwd):/kill-sticky kill-sticky

This will update the project README.md with the build version.
