Ever been blinded by the brightness of a website late at night? If you’ve ever browsed 4chan in a pitch-dark room, you know the struggle. The bright white background can hurt your eyes. Luckily, there’s a fix — Dark Mode.

TLDR:

4chan has built-in options for enabling Dark Mode through its settings menu. It’s super easy to change your theme to a darker palette with just a few clicks. If you want more customization or a darker dark mode, browser extensions can help. Either way, your eyes will thank you.

What Is Dark Mode?

Dark Mode is a setting that changes a website’s background from light to dark. It reduces eye strain, especially in low-light environments. It also looks pretty cool. Not every site has it built-in — but good news: 4chan does!

Why Use It on 4chan?

  • Comfort: Easier on the eyes at night.
  • Style: Looks sleek and modern.
  • Battery-Friendly: Saves energy on OLED screens.
  • Readability: Less glare = easier to read posts.

How to Enable Dark Mode on 4chan

Let’s get to the point. Enabling Dark Mode on 4chan is quick and painless. Follow these simple steps:

Step-by-Step Guide:

  1. Go to 4chan in your browser.
  2. Look to the top-right of the page. You’ll see a gear icon ⚙️ — this is your settings menu. Click it.
  3. Navigate to the “Options” tab (it usually opens here by default).
  4. Scroll down until you find something called “Theme” or “Style.”
  5. Click the drop-down menu next to it.
  6. Select a theme like “Yotsuba B” (dark) or “Tomorrow” theme, or any other that looks dark to you.
  7. Click “Save Settings” at the bottom.

That’s it! You’ve just gone dark. 😎

Don’t See a Dark Theme You Like?

No worries! 4chan’s built-in themes are basic, but you can level up your experience using browser extensions.

Try a Browser Extension

Here are a few awesome browser tools to give you custom control:

  • Stylus (Chrome/Firefox): Lets you apply custom user styles (CSS) to any website.
  • Dark Reader: Automatically makes websites darker without messing up usability.
  • Midnight Lizard: Offers ultra-fine control of colors and styles.

Quick Stylus Setup:

  1. Install the Stylus browser extension.
  2. Go to a user-style site like userstyles.world.
  3. Search for “4chan dark mode” or similar keywords.
  4. Click on a style you like and hit “Install Style”.
  5. Reload 4chan — boom! Custom dark theme!

With extensions, you can fine-tune everything — background, text color, quote text, and even spoiler tags. It’s like giving your internet a new outfit.

Customize with CSS (Advanced)

Feeling techy? Dive into custom CSS.

Here’s a simple snippet you can use in Stylus if you want a super dark sleek look:


body {
  background-color: #121212 !important;
  color: #e0e0e0 !important;
}
.reply, .post {
  background-color: #1e1e1e !important;
  border: 1px solid #333 !important;
}

Feel free to tweak these values to fit your vibe.

Things to Keep in Mind

  • Be sure to save your settings or changes may disappear.
  • If you clear cookies, you may lose your theme preferences unless you save them to your account or back them up.
  • Some user styles may break when 4chan updates its layout. Just grab a newer version or update your CSS.

Mobile Browsing? Try These Tips

Using 4chan on your phone? Dark mode can still be your friend. Most mobile browsers support extensions or have their own dark mode features.

If You Use Chrome on Android:

  1. Go to Chrome Settings.
  2. Tap “Theme.”
  3. Choose “Dark.”

Or Try an App:

  • Chanu – A 4chan browser with dark theme options.

Note: These apps are not official and may have varied support. Always download from trusted sources.
