## What it is
Salesforce Lightning Design System (SLDS) is the CSS framework and markup guidelines for building UIs with the Salesforce Lightning look and feel. Development is done with Storybook, including linting and accessibility validation tooling.

## Use cases
- build salesforce apps with lightning look and feel
- css framework for enterprise ui components
- accessible html/css component blueprints
- keep ui consistent with salesforce design
- design system tokens and styling guidelines

## When to choose
- building apps inside or alongside the Salesforce ecosystem
- you need the Lightning look and feel with maintained CSS/blueprints
- you want accessibility-validated HTML/CSS components

## When to avoid
- building non-Salesforce apps where a neutral design system fits better
- you need JavaScript component logic rather than CSS/markup
- you want a framework-agnostic React/Vue component library
