Theme Studio for LeetCode – Custom Themes, Dark Mode & Anime Backgrounds

Description

Custom LeetCode themes and dark mode for the code editor and problem page. Set any picture or anime scene as your background. Custom LeetCode themes, dark mode and your own background image for the whole problem page. Theme Studio is a theme extension that restyles everything you code in: the code editor and its syntax highlighting, the problem description, the testcase console, the panels and the top bar. Pick one of eight handcrafted themes, or turn any picture into your own, from an anime wallpaper to a photo of your desk. Text stays readable on every background, because the contrast is calculated from your picture. Everything switches instantly in every open tab, with no reload, and Off brings the default look back. Works on leetcode.com and leetcode.cn, in Chrome and Firefox. Made for anyone who practices DSA, preps for coding interviews at FAANG and big tech, does daily challenges or competitive programming, and wants a dark theme, a night mode or simply a nicer place to solve problems. EIGHT THEMES • Anime Studio: 18 anime scenes, a different one for each difficulty, or your own picture. • Pixel Art: an 8-bit world. Submit an Accepted answer and a pixel gunner blasts the page to pieces, then rewinds it. • 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. • 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. A REAL CODE EDITOR COLOR SCHEME Each look recolors the editor with its own palette, so keywords, functions, types, strings and numbers all get a distinct color you can tell apart at a glance. Every color is checked for contrast, so the night-mode looks never cost you readability. ANIME STUDIO: ANY PICTURE AS YOUR WALLPAPER • 18 scenes included, from moonlit shrines to city nights and dragons. Or add your own image. • 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 art, and the editor's colors are generated from it. • Readable by design: the glass is solved for each picture, so no setting can make your code unreadable. • Episode title cards: open an unsolved problem and it plays like an episode, with the title and the arc. Japanese text can be switched to English. • 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. FOCUS MODE FOR CODING INTERVIEWS AND CONTESTS One shortcut (Ctrl+Shift+.) hides the art, the animations and the sound, so you can sit a mock interview or a weekly contest 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. Found a bug or want something new? Use Report bug in the popup, or Connect to reach the developer.
