Prefectly describes vertical scroll direction without the jitter
ScrollDir is a micro Javascript library that perfectly describes vertical scroll direction in a html data attribute. From there, do what want. 💪
npm
npm install scrollDir --save
bower
bower install scrollDir --save
yarn
yarn add scrolldir
Add dist/scrolldir.min.js.
scrollDir();
By default ScrollDir will set the data-scrolldir attribute on the <html> element to up or down:
<html data-scrolldir="up">
or
<html data-scrolldir="down">
You can then change your styling based on vertical scroll direction.
[data-scrolldir="down"] .my-fixed-header { display: none; }
To use an attribute besides data-scrolldir:
scrollDir({attribute: 'new-attribute-name'});
To add the Scrolldir attribute to a different element:
scrollDir({el: 'your-new-selector'});
To turn Scrolldir off:
scrollDir({off: true});
This is a modular version of pwfisher's scroll-intent. ~TY!
