Is there any equivalent to Android's <meta name='viewport' content='target-densitydpi=device-dpi'> for Safari on the iPhone?
When setting meta name='viewport' content='target-densitydpi=device-dpi'
, the Android browser and Opera Mobile treats a CSS pixel as a device开发者_如何学编程 pixel on my device, leaving my stylesheets unmolested.
Is there any equivalent feature that works in Safari on the iPhone?
On my already mobile-friendly, high-DPI-optimized, media-query-powered web application, I'd really appreciate if the browser left my stylesheets alone.
(My full viewport declaration looks like this: meta name='viewport' content='width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no; target-densitydpi=device-dpi'
)

You can write like this
<meta name="HandheldFriendly" content="True">
<meta name="MobileOptimized" content="320">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

It seems that there's no target-densitydpi in safari. For what contents in Viewport of safari, look Configuring the Viewport.
safari support viewport and its attributes but not target-densitydpi. please refer this link https://developer.apple.com/library/archive/documentation/AppleApplications/Reference/SafariHTMLRef/Articles/MetaTags.html#//apple_ref/doc/uid/TP40008193-SW1
