🆚 DNS Prefetch vs. Sass

The rel="dns-prefetch" attribute on HTML <link> elements instructs web browsers to resolve domain names for external resources before those resources are requested.

It is commonly used for third-party domains serving scripts, fonts, analytics, advertisements, or media files, helping reduce DNS lookup latency and improve loading performance for external connections.

Sass ("syntactically awesome style sheets") is a stylesheet language that compiles to CSS and allows developers to use variables, nested rules, mixins, and functions.
