I’m trying to present a simple message to the user in my mobile website.
I want the message size approximately will be the same on mobile devices with similar screen size, for example iPhone and Samsung Galaxy (android).
I read a lot of posts on this issue, and many recommended to use -webkit-text-size-adjust: 100% to make it happen. But I didn’t understand how to use it…
The webpage:
<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
html { -webkit-text-size-adjust:100%; }
</style>
</head>
<body>
<div style="text-align:center;font-size:6em;-webkit-text-size-adjust:100%;">
Hello World!
</div>
</body>
</html>
The result:

Did you test the viewports meta?
