My landing page looks great on desktop but breaks on mobile, how do I stop that from happening?

A starting point

Design the page on your phone first, because that's where most of your traffic actually opens it, then let desktop be the afterthought. In no-code builders this means checking every section in the mobile preview and fixing stacking, font size, and button tap targets before you ship. The most common breaks are images that overflow and text that shrinks to unreadable, so hunt those two first.

Why we picked it Kevin Powell walks through why layouts that look fine on desktop fall apart on smaller screens, and the fixes are the exact culprits behind most mobile breaks: fixed pixel widths, missing flexible units, and clumsy media queries. He builds it visually so you see the break and the fix side by side rather than just reading rules. It is a practical starting point for anyone whose landing page shrinks badly on a phone.

Responsive design made easy

On YouTube by Kevin Powell about 43 minutes

Swap hardcoded px widths for relative units and max-width so content flexes instead of overflowing on narrow screens.
Use min(), max(), and clamp() to size things fluidly and lean less on brittle breakpoints.
Build mobile first, then layer on desktop enhancements, rather than shrinking a desktop layout down.

Why we picked it This is the free, built-in way to see exactly where your landing page breaks: open DevTools, toggle the device toolbar, and drag the viewport from a narrow phone width up to desktop. It is the fastest feedback loop because it is already in the browser you use every day, no signup or install. Treat it as a starting point for spotting the break, then confirm on a real phone since the simulator cannot reproduce everything.

Simulate mobile devices with Device Mode (Chrome DevTools)

From Chrome for Developers by Google Chrome Developers

Toggle the device toolbar (Cmd/Ctrl+Shift+M) and drag the edges to watch the layout at every width, so you catch the exact point it breaks.
The Show media queries view highlights which CSS breakpoints are firing, which is usually where a desktop-only layout falls apart on mobile.
It simulates from your laptop, so do a final check on an actual phone before you ship.
