responsive-classes v0.3.0
responsive-classes
A Vanilla JS library that adds classes to the <body> which can be used to apply responsive styles.
It is lightweight (673B minified and gzipped), has no dependencies and is documented with comments. Check out responsive-classes.js file.
Dafault breakpoints:
| Class name | Maximum width |
|---|---|
| .xs | 544px |
| .sm | 767px |
| .md | 992px |
| .lg | 1199px |
| .xl | 10000px |
Usage
Import
import * as responsiveClasses from 'responsive-classes';or
<script src="./path/to/responsive-classes.min.js"></script>Default usage
To use default classes simply call the function
responsiveClasses();Custom classes
To use custom classes provide an argument to the responsiveClasses() function like this:
responsiveClasses({
sm: 767,
md: 992,
lg: 1199,
xl: 3000,
xxl: 10000
});The argument should be an object where property name is a class name and value is the maximum <body> width in pixels. Values should be a Number. The order is not important.
Body width used for calculations doesn't include scrollbar.
Helper classes
Helper classes allow you to style multiple breakpoints using one class. Two helper classes are created for each breakpoint. One with suffix -up is created for screen width bigger than minimun width of a breakpoint, and class with suffix -down is created for screen width smaller than maximum width of a breakpoint.
To use helper classes provide true as a second argument to responsiveClasses()
responsiveClasses(breakpoints, true);You have to provide breakpoints object as the first argument if you want to use helper classes.
Assuming that you use three breakpoint like this:
responsiveClasses({
sm: 767,
md: 992,
lg: 1199
}, true);You will get the following classes:
| Example screen width | Classes |
|---|---|
| 640px | .sm .sm-down .sm-up .md-down .lg-down |
| 1024px | .md .md-down .md-up .sm-up .lg-down |
| 1600px | .lg .lg-down .lg-up .md-up .sm-up |
Screen width values in the table above are used only for presentation

About
I was inspired by this article on writing nano libraries in JavaScript. The code is written in Vanilla JS and has no dependencies. It's not only lightweight (673B minified and gzipped), but it also has a clean interface, extensive validation and is well documented with comments.
