Leverage Vertical Scroll Direction with CSS 😎
ScrollDir, short for Scroll Direction, is a 0 dependency, ~1kb micro Javascript plugin to easily leverage vertical scroll direction in CSS via a data attribute. 💪
ScrollDir will set the data-scrolldir attribute on the <html> element to up or down:
<html data-scrolldir="up">
or
<html data-scrolldir="down">
Now it’s easy to change styles based on the direction the user is scrolling!
[data-scrolldir="down"] .my-fixed-header { display: none; }
npm
npm install scrolldir --save
bower
bower install scrolldir --save
yarn
yarn add scrolldir
Add dist/scrolldir.auto.min.js and you’re done. There is nothing more to do! Scrolldir will just work.
Now go write some styles using [data-scrolldir="down"] and [data-scrolldir="up"].
Add dist/scrolldir.min.js. You have access to the API options below and must invoke scrollDir.
scrollDir();
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. If you'd like to easily use scrolldir with jQuery—use Scroll Intent. ~TY!
