cleanupEnableBackground

Default

Cleans up enable-background, unless the document uses <filter> elements.

Only cleans up attribute values and inline-styles, but does not affect stylesheets in <style> nodes.

This plugin will:

Drop enable-background when the width and height values match the width and height of the <svg> node.
Replace the value with new when the width and height values match the width and height of a <mask> or <pattern> node.

info

Some browsers don't support enable-background, so it's best to avoid the attribute regardless.

Usage

svgo.config.js
module.exports = {
  plugins: [
    "cleanupEnableBackground"
  ]
}
