I have an issue with the display of my webpage across different devices and screen sizes. The page appears as intended on my 16-inch and 24-inch displays, with the hero form fitting the first fold. Here’s how it looks on my Mac:
However, when viewed on my client’s 15-inch PC, the site appears disproportionately larger, causing the form to exceed the viewport height. Here’s a screenshot:
each computer monitor has option change its resolution that can allow people with visual impairment lower resolution and all become bigger. check your computer or laptop monitor setting where you will find these options.
It always will be 16px but can be bigger because of lower resolution will have “bigger” pixel. Ask your client check website on other computer.
It is clearly on his/her site and all you can do is to figure out what he/she has done and help him/her to fix it. You will be help desk support level 1. Ask him/her questions and explain like he/she is 5.
The best option will be video chat with shared screen.
