Missing Viewport Meta Tag
Without a viewport tag, mobile browsers render at desktop width and zoom out. Here's the one-line fix.
What it means
The page <head> doesn't include <meta name="viewport" content="width=device-width, initial-scale=1">.
Why it matters
Mobile browsers fall back to a 980px desktop viewport, scaling the whole page to fit. Tap targets become tiny, text unreadable.
How to fix it
- Add the viewport meta tag to every page's <head>.
- Test on a real mobile device or Chrome DevTools mobile emulation.
Example
Before
<head>

<meta name="viewport" content="width=device-width, initial-scale=1" />

Frequently asked questions
Should I add user-scalable=no?
No — it breaks accessibility for users who need to zoom.
