Your Site Looks Different in Different Browsers
Your website looks fine in one browser but broken or off in another, like Safari versus Chrome.
Common signs of this issue
- Layout, fonts, or spacing differ noticeably between Safari, Chrome, Firefox, or Edge.
- Something works in one browser but not another (a button, menu, or form).
- The site looks right on your computer but wrong on a colleague's.
- An older browser shows a badly broken version.
Safe checks you can do yourself
None of these require sharing passwords with anyone.
- Reproduce it cleanly: open the page in the problem browser using a private/incognito window to rule out extensions and old cache.
- Hard-refresh (or clear cache) in the affected browser — a stale cached file is a frequent cause.
- Check whether the browser or device is simply out of date; very old browsers can't render modern layouts.
- Note exactly what differs and in which browser and version — a precise description speeds up any fix.
- Test on a second device of the same type to confirm it is the browser, not one machine's settings.
What this usually means
Browsers interpret modern web code slightly differently, and they cache files aggressively. Most cross-browser issues come from a stale cache, an outdated browser, or code that relies on something one browser supports and another does not.
Genuine rendering differences usually trace to specific styles or scripts that need a small compatibility adjustment — not a rebuild of the whole site.
What not to do
- Don't assume the site is broken for everyone because one browser misbehaves — confirm how widespread it is first.
- Don't make big design changes based on a single outdated browser.
- Don't ignore Safari/iPhone differences — a large share of visitors use them.
When to get help
If a real cross-browser bug is affecting visitors (especially on iPhones), a developer can usually pinpoint the offending style or script and fix it quickly without disturbing the rest of the design.

Frequently asked questions
Why does it look fine for me but not for a visitor?
Often a cached file, a browser extension, or a different browser version. Test in a private window and hard-refresh to compare like for like.
Do I need to support every old browser?
Support the browsers your visitors actually use (your analytics will show this). It's rarely worth heavy effort for very old or rare browsers.
