Theme Studio for LeetCode – Dark Themes & Anime Backgrounds

Custom LeetCode themes and dark mode for the code editor and problem page. Set any picture or anime scene as your background.

Make the LeetCode problem page yours. Six crafted themes restyle the whole problem page: the editor and its syntax colours, the panels, the console, the top bar and even the typography. They are designed as materials, not just colour swaps. ANIME STUDIO Turn any picture into your LeetCode theme. • 18 scenes included, from moonlit shrines to dragons and city nights. Or add your own picture. • Scenes follow the story: a calm sunset for Easy (slice-of-life arc), a moonlit shrine for Medium (training arc), a crimson dragon for Hard (final battle). Pick your own for each. • Share your clears: after an Accepted submission, get a personal "episode cleared" card with your scene, the problem, your Beats % and your streak, ready for LinkedIn or X in one click. Turn it off anytime. • The panels become glass over your scene, and the editor sits on frosted glass. • Readability is guaranteed. The glass opacity is calculated from your picture so text always clears strong contrast, and no setting can make your code unreadable. • Syntax colours are generated from your picture, so the code matches the art and every token type gets its own distinct colour. • Episode title cards: open a problem you haven't solved yet and it plays like an episode, 「第1話」 with the title and the arc (日常編 easy, 修行編 medium, 最終決戦 hard). • Verdict moments with sound effects: 「完了！」 when you get Accepted, 「よし！」 when tests pass, a dizzy 「まだだ…」 with spinning stars when a submission fails, 「時間切れ」 when time runs out. • Focus mode: one shortcut (Ctrl+Shift+.) hides the scene, moments and sound. Built for contests and interviews. THE MATERIAL THEMES • Vintage Paper: crumpled kraft paper on a walnut desk, with ink colours tuned for the paper. • Sakura Night: petal pink and cold cyan on plum-indigo. • Grid: a drafting table with hard edges and monospace type. • Orchid: silk velvet with rose-gold trim. • Web Crawler: near-black charcoal tiled with tiny spun webs, deep crimson and electric blue. BUILT TO STAY OUT OF YOUR WAY • Switches instantly on every open problem tab, with no reload. "Off" gives LeetCode back its own look. • Nothing animates while you type. Moments run only on events and clean up after themselves. • No lag: scrolling and typing were measured and match stock LeetCode. • Quiet focus styling: no rings when you click, and a subtle ring when you use the keyboard. PRIVATE BY DESIGN • No accounts, no analytics, and no network requests. • Your settings and your own picture stay in your browser. • Runs only on LeetCode problem pages.
