You can contribute to and help Dark Reader in many ways. Read on below to learn how and thank you in advance.

If a website is already dark and meets the following requirements:
- The entire website, including all subpages, is dark by default, regardless of the system's preferred color scheme.
- The URL is the actual website address. No redirects of any kind are allowed.
- The website is complete and finished. Any website in the design or development phase or any other incomplete status is not permitted. These statuses can include any placeholder web pages or verbiage about coming soon, the website being under construction, the website having moved, etc.
Then you can add it to the dark-sites.config file.
Please maintain the alphabetical order of the websites listed in this file.
If any element on a web page is not inverted or styled correctly, you can fix it by specifying the appropriate CSS selector. Use the dynamic-theme-fixes.config file for Dynamic Theme mode and the inversion-fixes.config file for Filter and Filter+ modes.
Please maintain the alphabetical order of the websites listed, use short selectors, and preserve the code style in these files.
You can learn how to create a fix for the appropriate mode below.
The Dev Tools help you fix minor issues on a web page. These can include a dark icon on a dark background, removing a bright background, adding a white background to a transparent image, etc.
In Dynamic mode, if the page looks partially dark and bright, it is considered a bug.
In Filter mode, it is a common practice to invert elements on the page that are already dark.
- Open Chrome Dev Tools (
F12
) in Chrome or "Inspector" (Ctrl+Shift+C
) in Firefox. - Click on element picker (top-left corner). It is enabled automatically in Firefox.
- Pick an incorrectly inverted element.
- Choose a selector for that element or all similar elements (for example, if it has
class="icon small"
, the selector may look like.icon
). - Click Dark Reader icon.
- Click Open developer tools (at the bottom of the Dark Reader popup).
- Edit or add a block containing the URL and selectors to invert.
- Click Apply.
- Check how it looks both in Light and Dark mode.
- If the fix works open dynamic-theme-fixes.config file or inversion-fixes.config file.
- Click Edit (login to GitHub first).
- Insert your fix there. Preserve alphabetic order by URL.
- Provide a short description of what you have done.
- Click Propose file change.
- Review your changes. Click Create pull request.
- GitHub actions will run tests to make sure it has the right code style.
- If you see a red cross, click Details to see what is wrong and edit the existing Pull Request.
- When you see a green checkmark then everything is fine.
- A Dark Reader developer will review and merge your changes, making them available.

IGNORE IMAGE ANALYSIS
.logo
Rule | Description | Notes / Examples |
---|---|---|
INVERT | Inverts specified elements. | Dynamic Mode: INVERT only for dark images that are invisible on dark backgrounds. |
CSS | Adds custom CSS to a web page. | !important keyword should be specified for each CSS property to prevent overrides by other stylesheets.Dynamic mode supports ${COLOR} template, where COLOR is a color value before the inversion. Example: ${white} will become ${black} in dark mode. |
IGNORE INLINE STYLE | Prevents inline style analysis of matched elements. | Example: <p style="color: red"> element's style attribute will not be changed. |
IGNORE IMAGE ANALYSIS | Prevents background images from being analyzed for matched selectors. |
If you can add a new popular or unique but usable predefined color scheme to Dark Reader, you can add it to the src/config/color-schemes.drconf
file. Please use the following steps to add a new color scheme:
- Open color-schemes.drconf file.
- Click Edit (login to GitHub first).
- Insert your fix there. Preserve alphabetic order by Color scheme name.
- Provide a short description of what you have done.
- Click Propose file change.
- Review your changes. Click Create pull request.
- GitHub actions will run tests to make sure it has the right code style.
- If you see a red cross, click Details to see what is wrong and edit the existing Pull Request.
- When you see a green checkmark then everything is fine.
- A Dark Reader developer will review and merge your changes, making them available.
When making a fix for background or text colors, instead of using hardcoded colors (like #fff
, #000
, black
or white
), please use CSS variables that are generated based on the user settings:
dynamic-theme-fixes.config
================================
example.com
CSS
.logo {
background-color: var(--darkreader-neutral-background) !important;
}
.footer > p {
color: var(--darkreader-neutral-text) !important;
}
Here is a full table of available CSS variables:
Variable | Description | Use |
---|---|---|
--darkreader-neutral-background |
Neutral background color that corresponds to the user's settings. |
Mostly used for elements that have the wrong background color. |
--darkreader-neutral-text |
Neutral text color that corresponds to the user's settings. |
Used for elements with the wrong text color. |
--darkreader-selection-background |
The background color setting defined by the user. |
The user's Background Color setting. |
--darkreader-selection-text |
The text color setting defined by the user. |
The user's Text Color setting. |

- Filter and Filter+ work by inverting the entire web page and reverting necessary elements (images, videos, etc.) listed in the
INVERT
section. - If an inverted element contains images or other content that becomes incorrectly displayed, use the
NO INVERT
rule. REMOVE BG
removes the background image from an element and forces a black background.
