First you need to know why the click on the mobile side is dull?
Google's developer document 300MS tap delay, gone away can find the reason
The mobile side to determine is not a double-click, so after clicking can not immediately fire click, to wait 300ms, until the confirmation is not double-click to trigger click. So it causes the click to have a delay. Method 1<meta name= "viewport" content="Width=device-width" > is to set the viewport to the actual pixel of the device, there will be no 300ms delay, and is supported by the Ie/firefox/safari (IOS 9.3), that is, mobile development now can not be concerned about the click will be more sluggish. Method 2 sets initial-scale=1.0, which is available on Chrome, but Safari does not:<meta name= "viewport" content="initial-scale=1.0" > Method 3Set CSS:HTML {touch-action:manipulation; }This also cancels out the 300ms delay, which both Chrome and Safari can take effect.
