Tag Syntax in Viewport

Question

I look on the Internet, and I'm still confused about what kind of work and not. I see errors on chrome when I use half a time, but iPhone recognizes it. The comma also works without errors. I wonder which one qualifies as the correct way to write it.

Half Columns -

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" /> 

Commas -

 <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" / >

I'm just looking for the correct interpretation of why I have this error if they work, especially why it throws an error in Chrome.

EDIT: woops, forgot the code tags. updated.

Answer 1

Commas are the correct delimiters for viewport properties. iPhone Safari (and other browsers) may be more forgiving and interpret semicolons as delimiters, but then you rely on browser error handling.
