PRem

PRem ist the fastest way to convert pixel values into rem units directly via IntelliSense in VS Code.

Type a number followed by the custom keywords prem or pxrem, then accept the suggestion. If completion is unavailable or disabled, select a value like 16px and run PRem: Convert Selection to rem.

PRem is scoped to style-heavy languages such as CSS, SCSS, Sass, Less, HTML, Vue, Svelte, and Astro.

Examples:

• 16prem → 1rem
• 16pxrem → 1rem
