Cartoon CSS Effect Tutorial - How to Create Cartoon

Learn how to create the cartoon CSS effect. Thick borders, hard-offset shadows, bold colors, sticker-like depth.

AI agents blur their shadows and skip the border. The cartoon/neobrutalism look needs zero-blur hard-offset shadows paired with thick borders on every element, a consistent shadow direction, warm background instead of pure white, and press states where the shadow shrinks as the element translates. Agents get the shadow wrong every time.

Copy and paste this cartoon CSS code into your AI coding agent (Claude, ChatGPT, Cursor) for instant implementation.
