W3C don't validate my viewport meta tag any idea why?
<title>DIDIx13</title>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no" />
<!-- Throws a warning "Consider avoiding viewport values that prevent users from resizing documents." -->
<meta name="keywords" content="DIDIx13" >
<meta name="description" content="I'm Darwin and welcome to my website" >
Remove "user-scalable=no"
and now the validator is fully ok!
I've found out the purpose of "user-scalable=no"
, thanks to this answer.
Actually
"user-scalable=no"
prevents the user from zooming. And it allows the browser to gain 300ms per click.
300ms per click? That's pretty damn good! I should let "user-scalable=no"
But this is no longer the case, according to efheng's answer.
<meta name="viewport" content="width=device-width">
is enough to remove 300ms delay.
