Use PostHTML Inline Assets to process your HTML:

`js
const posthtml = require('posthtml')
const posthtmlInlineAssets = require('posthtml-inline-assets')

posthtml([
posthtmlInlineAssets(/ pluginOptions /)
]).process(YOUR_HTML /, processOptions /)
`

#### Gulp

Add [Gulp PostHTML] to your build tool:

`

Use [PostHTML Inline Assets] in your Gulpfile:

`js
const posthtml = require('gulp-posthtml');
const posthtmlInlineAssets = require('posthtml-inline-assets');

gulp.task('css', () => gulp.src('./src/*.css').pipe(
posthtml([
posthtmlInlineAssets()
])
).pipe(
gulp.dest('.')
));
`

#### Grunt

Add [Grunt PostHTML] to your build tool:

`bash
npm install grunt-posthtml --save-dev
`

Use [PostHTML Inline Assets] in your Gruntfile:

`js
const posthtmlInlineAssets = require('posthtml-inline-assets');

grunt.loadNpmTasks('grunt-posthtml');

grunt.initConfig({
posthtml: {
options: {
use: [
posthtmlInlineAssets()
]
},
dist: {
src: '*.css'
}
}
});
`

Options

$3

The cwd option specifies the working directory used by an HTML file, and it
is used to determine the relative location of assets. By default, the current
file directory is used, otherwise the current working directory is used.

`js
const posthtmlInlineAssets = require('posthtml-inline-assets');

posthtmlInlineAssets({
cwd: '/path/to/files'
});
`

`html


`

$3

The root option specifies the root directory used by an HTML file, and it
is used to determine the absolute location of assets. By default, the current
file directory is used, otherwise the current working directory is used.

`js
const posthtmlInlineAssets = require('posthtml-inline-assets');

posthtmlInlineAssets({
root: '/path/to/files'
});
`

`html





`

$3

The errors option specifies how transform errors should be handled,
whether those errors occur when a resolved asset cannot be read, or when
something goes wrong while an asset is being transformed. The default
behavior is to ignore these errors, but they may also throw an error,
or log a warning.

`js
const posthtmlInlineAssets = require('posthtml-inline-assets');

posthtmlInlineAssets({
// throw an error whenever a resolved asset fails to inline
errors: 'throw' // the options are to 'throw', 'warn', or 'ignore' errors
});
`

$3

The transforms option specifies the transforms used to inline assets. New
transforms can be added by creating a child object with two functions;
resolve and transform.

#### resolve

The resolve function is used to determine the path of an asset. It is passed
the current node, and it must return the path of the asset to be inlined. If it
does not return a string, the asset will not be transformed.

`js
function resolve(node) {
// if the node is a element then always return 'some/path'
return node.tag === 'foo' && 'some/path';
}
`

#### transform

The transform function is used to transform the asset being inlined. It is
passed the current node as well as an object containing the buffer, the full
path, and the mime type (if available) of the asset. It may also return a
promise if an asynchronous transform is required.

`js
function transform(node, { buffer, path, mime }) {
// always inline the contents as a child of the node
node.content = [ buffer.toString('utf8') ];
}
`

The default transforms can be modified to alter their functionality. For
instance, script.resolve might be changed so that
