Found this minor and weird issue, but it may be of interest.
For my contact form: https://hi-flyfoto.de/luftaufnahmen-kontakt-angebot I have set the border colour to grey with quick CSS.
On a tablet (ipad air 2, various browsers) the border of the email field is invisible when the validation is set to valid email address.
While the page is loading the border can be seen, but it then goes away. This is not the case on a desktop.
Setting the validation to must be filled out, “solves” the problem and that is the way I have it set up now.
Like I say, not a big deal.
Hey mleonhard,

Best regards,
