Media query not working as expected on iPad Pro - css

Question

I've got my visitor portal setup for 3 types of devices: mobile (less than 800px width), low-res desktop and hi-res desktop, like this:
<link media="only screen and (min-width: 801px) and (max-height: 899px)" href="..." rel="stylesheet" type="text/css">
<link media="only screen and (min-width: 801px) and (min-height: 900px)" href="..." type="text/css">
<link media="only screen and (max-width: 800px)" href="..." rel="stylesheet" type="text/css">
All this works rather well but with the iPad Pro portrait, the width of the screen is less than 800px but the stylesheet that's selected is the low-res desktop. What do I need to change to make it work?
Edit (to clarify the problem)
When I do something like this
<link media="only screen and (min-width: 801px) and (max-height: 899px)" href="..." rel="stylesheet" type="text/css">
<link media="only screen and (min-width: 801px) and (min-height: 900px)" href="..." rel="stylesheet" type="text/css">
<link media ="only screen and (max-width: 800px),
only screen and (max-device-width:1024px) and (-webkit-min-device-pixel-ratio:1.1) and (orientation:portrait),
only screen and (max-device-height:1366px) and (-webkit-min-device-pixel-ratio:1.1) and (orientation:landscape)"
href="..." rel ="stylesheet" type="text/css">
The problem is that the styles get mixed-up at different resolutions. I'm looking to make it work so that only one stylesheet is active at anytime.

So, if i were you, I will do something like this:
<!-- small devices non-retina (apple use 2x for ipads and 3x for the newest iphones) -->
<link media="only screen and (max-width: 800px)" href="..." rel="stylesheet" type="text/css">
<!-- small devices retina (apple use 2x and 3x) -->
<link
media="only screen and (-webkit-min-device-pixel-ratio: 2) and (max-width: 800px),
only screen and (min--moz-device-pixel-ratio: 2) and (max-width: 800px),
only screen and (-o-min-device-pixel-ratio: 2/1) and (max-width: 800px),
only screen and (min-device-pixel-ratio: 2) and (max-width: 800px),
only screen and (min-resolution: 192dpi) and (max-width: 800px),
only screen and (min-resolution: 2dppx) and (max-width: 800px)"
href="..." rel="stylesheet" type="text/css">
<!-- bigger devices low-res -->
<link media="only screen and (min-width: 801px) and (max-height: 899px)" href="..." rel="stylesheet" type="text/css">
<!-- bigger devices higher res -->
<link media="only screen and (min-width: 801px) and (min-height: 900px)" href="..." rel="stylesheet" type="text/css">
If you see in this article of CSS Tricks: Media Queries for Standard Devices you can go very specific trying to point each devices. Or get use of some of this examples (maybe in combination with orientation: portrait)
Lastly I'll like to say that, personally, I only use the -webkit-min-device-pixel-ratio: 2 or -webkit-min-device-pixel-ratio: 3 to point to the high-res raster/bitmap images (jpg and png) I'll use.
I hope this help.
You can find more info about 2x and 3x devices and how this affects images on this article from Apple.

Answer 3

iPad pro has a retina display, with a pixel aspect ratio of probably 2, which makes virtually 2 x 800 = 1600 pixels. That's why the selected media query is the wrong one. You'll have to deal with pixel aspect ratio too. See this : https://css-tricks.com/snippets/css/retina-display-media-query/

This Query working on all device I hope your issue is resolve.
#media only screen and (max-width:767px){

Answer 5

have you included <meta name="viewport" content="width=device-width, initial-scale=1.0"> in your <head>? I find including this makes retina devices behave as expected without any extra fiddling with 2x and 3x devices mentioned by f-spin
edit: just beware, you may find this affects layout that currently works well, but overall should make media queries more predictable once you've got over that (probably quite small) hump

Answer 6

As per my knowledge resolution of iPad Pro is (1024x1366)px and iPad Pro9.7 is (768x1024)px. So if you want to load specific stylesheet for specific resolution, then you might be load the stylesheet of
<link media="only screen and (min-width: 768px) and (max-width: 1199px)" href="..." rel="stylesheet" type="text/css">
I think this will help you.
