Bootstrap Cheat Sheet is a fast, keyboard-friendly Chrome Extension that puts the entire Bootstrap 5 class reference one click away — without leaving your browser tab. What's inside: 200+ Bootstrap 5 classes organized across 11 categories: Grid, Typography, Spacing, Flex, Colors, Display, Buttons, Forms, Validation, Components, and Utilities Instant search — type any class name or keyword and results filter in real time One-click copy — click any row to copy the class name directly to your clipboard Clean dark theme built for long coding sessions Links directly to the official Bootstrap 5 documentation Who it's for: Whether you're building a quick prototype or deep in a production layout, this extension saves you from switching tabs to look up .d-flex, .justify-content-between, or that spacing utility you always forget. Everything is right there in the popup, organized the way developers actually think. Categories covered: Grid (containers, rows, columns, gutters, offsets) · Typography (headings, display, alignment, weight) · Spacing (margin, padding, gap — all breakpoints) · Flex (direction, justify, align, wrap) · Colors (background, border, opacity) · Display (d-{value}, position, overflow, visibility) · Buttons · Forms & Validation · Components (Alert, Badge, Card, Navbar, Modal, Table, Spinner, and more) · Utilities (border, sizing, shadow, z-index, ratio) No internet connection required. No tracking. No permissions beyond displaying a popup.
