You probably know, you have to test your site in different browsers. It might look different in one browser. But do you remember all the important browsers?
The browsers recorded as most used on mobile phones, are Chrome, Safari, and Firefox. But you might be forgetting two significant browsers – although you are probably responsible for them being used.
If you share your website on social media – and who doesn’t? – your network will be subject to using either the in-app Facebook browser, Instagram browser, or Linkedin browser if they are on their mobile phones.
This real example means the visitor will get a completely different input from the H1 on the site. Actually, the most important message goes from 100% sustainable to 0% sustainable. That is probably not the story they want to promote.


Here are other examples. The text is typically to wide in the in-app browser, whilst working fine in the system-browser (which is Chrome on my phone). The site was probably tested in Chrome.


Remember to test your site in the in-app browsers if you plan to share the site on social media!
