Salesforce Lightning Design System (SLDS)

The Salesforce Lightning Design System (SLDS) provides HTML and CSS component blueprints, design tokens, and utility classes for building applications visually consistent with Salesforce Lightning Experience. Developers reference SLDS in Lightning Web Components, Aura components, and Visualforce pages to match Salesforce's design language without including SLDS directly, as it is automatically available in the Lightning runtime.
