Bootstrap

Bootstrap

Bootstrap 5 dropped jQuery and embraced modern CSS (Grid, Flexbox, Variables). It remains the safest choice for admin panels and internal tools.

When to Use

• Prototypes: "Get it working" in 5 minutes.
• Admin Panels: Hundreds of templates available.
• Quick MVP: When custom design is a secondary concern.

Core Concepts

Grid System

The 12-column grid (col-md-6) is still the industry standard mental model.

Utilities

d-flex, mt-5, text-center. (Influenced Tailwind).

Components

Modals, Dropdowns, Navbars work out of the box (JS included).

Best Practices (2025)

Do:

• Use Data Attributes: data-bs-toggle="modal" (No JS code needed).
• Use CSS Variables: --bs-primary makes theming easy.
• Use SCSS: Customize the build by importing only needed parts.

Don't:

• Don't include jQuery: Bootstrap 5 doesn't need it.
