postcss-inline-svg Build Status

PostCSS plugin to reference an SVG file and control its attributes with CSS syntax.

@svg-load nav url(img/nav.svg) {
    fill: #cfc;
    path:nth-child(2) {
        fill: #ff0;
.nav {
    background: svg-inline(nav);
.up {
    background: svg-load('img/arrow-up.svg', fill=#000, stroke=#fff);
.nav {
    background: url("data:image/svg+xml;charset=utf-8,%3Csvg fill='%23cfc'%3E%3Cpath d='...'/%3E%3Cpath d='...' fill='%23ff0'/%3E%3Cpath d='...'/%3E%3C/svg%3E");
.up {
    background: url("data:image/svg+xml;charset=utf-8,%3Csvg fill='%23000' stroke='%23fff'%3E...%3C/svg%3E");

PostCSS parsers allow to use different syntax (but only one syntax in one svg-load() definition):

.up {
    background: svg-load('img/arrow-up.svg', fill: #000, stroke: #fff);
.down {
    background: svg-load('img/arrow-down.svg', fill=#000, stroke=#fff);


postcss([ require('postcss-inline-svg')(options) ])

See PostCSS docs for examples for your environment.



Path to resolve url.

Default: false - path will be relative to source file if it was specified.


Default: false - with true removes all fill attributes before applying specified. Passed RegExp filters files by id.


Processes svg after applying parameters. Default will be ommited if passed false.


function encode(code) {
    return code
        .replace(/%/g, '%25')
        .replace(/</g, '%3C')
        .replace(/>/g, '%3E')
        .replace(/&/g, '%26')
        .replace(/#/g, '%23');

options.transform(svg, path)

Transforms svg after encode function and generates url.


type: boolean
default: true

Adds xmlns attribute to svg if not present

Frequently asked questions

Why svg-load() doesn't work and the color still black (or red or whatever)?

That's because svg-load() overrides attributes only in <svg> element and children inherit that color. But if there is already color on children nothing will be inherited.

For example

    <path fill="#ff0000" d="..." />

after inline-svg (fill: #000) will looks like

<svg fill="#000">
    <path fill="#ff0000" d="..." />

There are three solutions: to remove that attribute (preferable), to use extended @svg-load notation or to use removeFill option.

How to optimize svg on build step?

There is a plugin. :)

You are able to add postcss-svgo in your postcss plugins list which will detect every url which contains data svg uri and minify via svgo.


Or if you use cssnano your svg urls already minified as cssnano includes postcss-svgo.
