Question 1

Why does my site need a favicon?

Accepted Answer

Favicons appear in browser tabs, bookmarks, search results, and mobile home screens. A missing favicon looks unprofessional and hurts brand recognition — browsers show a generic icon instead.

Question 2

What is a web app manifest?

Accepted Answer

A manifest.json file enables Progressive Web App (PWA) features: install prompts, splash screens, and standalone app behavior on mobile. It defines your app name, icons, theme color, and display mode.

Question 3

Why are viewport and charset important?

Accepted Answer

Without a viewport meta tag, mobile browsers render at desktop width making the site unusable on phones. Without charset, browsers may misinterpret characters causing garbled text and security issues.
