For example, it will turn the following feature query condition...\n\n```css\n@supports (display: flex) { /* styles here */ }\n```\n... Into the following...\n\n```css\n@supports not((display: flex)) { /* styles here */ }\n```\n\n## How to use\n\n**1. Install the Feature Queries Manager**\n\n- \u003cimg src=\"https://github.com/alrra/browser-logos/raw/master/src/chrome/chrome_256x256.png\" alt=\"Google Chrome Logo\" height=\"15\"\u003e [Download on Google Chrome](https://chrome.google.com/webstore/detail/fbhgnconlfgmienbmpbeeenffagggonp/)\n- \u003cimg src=\"https://github.com/alrra/browser-logos/raw/master/src/firefox/firefox_256x256.png\" alt=\"[Firefox Logo\" height=\"15\"\u003e [Download on Firefox](https://addons.mozilla.org/en-US/firefox/addon/feature-queries-manager/)\n\n(Other browsers TBA)\n\n**2. Open DevTools and see a new panel labelled \"FQM\"**\n\n![Screenshot of FQM](https://user-images.githubusercontent.com/8677283/39296534-12a99c72-4939-11e8-8416-0ef066a59eb4.png)\n\nThis page will display all the feature queries on the page (on the left) and any styles within those Feature Queries (on the right).\n\n**3. Toggle Feature Queries**\n\nOn the left panel, you will see the list of feature query conditions on the page, and a checkbox beside each condition.\n\n- **Uncheck** the checkbox to negate the feature query condition\n- **Check** the checkbox to re-instate the original feature query condition\n\n![Example of FQM toggle on and off](https://user-images.githubusercontent.com/8677283/39296696-81c1141e-4939-11e8-9c0a-ef92783c57ae.gif)\n","funding_links":[],"categories":["JavaScript"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fireade%2Ffeature-queries-manager","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fireade%2Ffeature-queries-manager","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fireade%2Ffeature-queries-manager/lists"}
