Sefaria - Night Mode

Adds a dark mode to Sefaria.org so it's easier to read.

# Sefaria - Night Mode (Chrome Extension) A dark theme for [sefaria.org](https://www.sefaria.org) — source texts, translations, source sheets, topics, and more — so the Hebrew and English text is comfortable to read at night without a blinding white background. This extension is an unofficial, independent project — it isn't made or endorsed by Sefaria. Sefaria itself is a nonprofit, and everything this extension displays (every text, translation, and source sheet) is only possible because Sefaria builds and hosts it, for free, for everyone. If this makes your learning a little easier, please consider donating to Sefaria directly:https://donate.sefaria.org/give/451346/#!/donation/checkout?c_src=Header) ## How it works Sefaria is a large, frequently-updated web app. An early version of this extension used the popular "invert the whole page with a CSS filter" trick, but that turned out to be unreliable on Sefaria specifically — Chrome has known bugs where an ancestor's `filter` doesn't reliably reach content sitting in GPU-accelerated/virtualized scroll layers, and Sefaria's reader text is rendered that way for performance. The result was invisible black-on-black Hebrew text. This version instead sets colors explicitly on Sefaria's real containers (`.textColumn`, `.readerPanel`, `.segment .he`, `.segment .en`, etc.), using plain CSS cascade/inheritance rather than a filter — which doesn't have that compositing problem. It's a bit more selector-heavy, but it's the reliable way to do this on Sefaria. Your on/off preference is saved (via `chrome.storage.sync`) and applied automatically the next time you visit Sefaria. ## Credits Sefaria - Night Mode was created by Marc Rosenberg ©2026 ## Dedication לזכר טובה — In appreciation of my chavruta, Dovid Bleier, whose learning and friendship pushed me to open more sefarim, ask better questions, and keep showing up to the daf. This is a small piece of code built in that spirit.
