Theme Studio for LeetCode av Vinay Tiwari

Give LeetCode a complete makeover. Theme Studio adds dark mode themes, a matching code editor theme with its own syntax colors, and a custom background image behind the problem page. Pick one of eight handcrafted LeetCode themes, or turn any picture into one: an anime wallpaper, a photo you love, your desk setup. Text stays readable on every background, because the contrast is calculated from your picture.

It restyles the whole page, not just the editor: the problem description, the code editor and its syntax highlighting, the testcase console, the panels, the top bar and the fonts. Themes switch instantly in every open tab with no reload, and Off gives you the default look back.

ANIME STUDIO
• 18 scenes included, from moonlit shrines to city nights and dragons. Or add your own picture.
• A scene for each difficulty: a calm train window for Easy, a moonlit shrine for Medium, a crimson dragon for Hard. Choose your own for each.
• Panels turn into frosted glass over the scene, and syntax colors are generated from the art, with every token type in its own color.
• Readable by design: the glass is solved for each scene so text always clears strong contrast. No setting can make your code unreadable.
• Episode title cards: open an unsolved problem and it plays like an episode, 「第1話」 with the title and the arc.
• Verdict moments with sound effects for Accepted, passed tests, Wrong Answer and Time Limit Exceeded.

SHARE YOUR ACCEPTED SUBMISSIONS AND STREAK
After an Accepted submission you get a card with the problem, difficulty, your Beats %, language, runtime and your daily solve streak, ready to post on LinkedIn or X in one click. You can turn it off anytime.

EIGHT THEMES
• Anime Studio: 18 scenes or your own picture.
• Vintage Paper: crumpled kraft paper on a walnut desk, a warm light look.
• Sakura Night: petal pink and cold cyan on plum indigo.
• Grid: a dark drafting table with hard edges and monospace type.
• Orchid: silk velvet with rose-gold trim.
• Web Crawler: charcoal webs, crimson and electric blue, with spiders that drop in on your verdicts.
• Adventure: an RPG night realm with quests and loot.
• Pixel Art: an 8-bit world. Submit an Accepted answer and a pixel gunner blasts the page to pieces, then rewinds it.

FOCUS MODE FOR CONTESTS AND INTERVIEWS
One shortcut (Ctrl+Shift+.) hides the scene, the animations and the sound, so you can practice for coding interviews and weekly contests without distraction.

FAST AND PRIVATE
• No lag: scrolling and typing were measured and match the stock site.
• Nothing animates while you type.
• No account, no sign-in, no analytics and no network requests. Your settings and pictures stay in your browser.
• Runs only on problem pages.
