How do I write a media query for Gmail?

问题

I am trying to write some HTML/CSS for an email but can't get things to show and hide responsively. I have one big table, with two nested tables. Each of the nested tables is a footer that is hidden or shown based on the screen size. Here's the code

        <style>
          @media all and (max-width: 768px) {
            table[table-view=desktop] {
              display: none !important;
            }

            table[table-view=mobile] {
              display: block;
            }
          }

          @media all and (min-width: 769px) {
            table[table-view=mobile] {
              display: none !important;
            }

            table[table-view=desktop] {
              display: block;
            }
          }
        </style>

    <some other stuff here>

<table class="module mobile-view" table-view="mobile" border="0" cellpadding="0" cellspacing="0" data-type="code" role="module" style="table-layout: fixed;">
...
</table>

<table class="module desktop-view" table-view="desktop" role="module" data-type="code" border="0" cellpadding="0" cellspacing="0" width="100%" style="table-layout: fixed;">
...
</table>

When looking at this in Gmail, both footers appear. When using the preview tool in the email building tool (SendGrid), it looks fine.

I tried selecting the mobile-view and desktop-view classes in the media query but that didnt work- so I tried putting attributes in the HTML.

What am I doing wrong?

Here is a working example. Its tested on Gmail App (v8.3.12).

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
	<style>
          @media only screen and (max-width:768px)  {
            .desktop-view{display: none !important;}
          }

         @media only screen and (min-width:769px) {
            .mobile-view{display: none !important;}
          }
        </style>
</head>

<body>
	
	

    <some other stuff here>

<table class="module mobile-view" table-view="mobile" border="0" cellpadding="0" cellspacing="0" data-type="code" role="module" style="table-layout: fixed;">
	<tr>
		<td> mobile content here </td>
	</tr>
</table>

<table class="module desktop-view" table-view="desktop" role="module" data-type="code" border="0" cellpadding="0" cellspacing="0" width="100%" style="table-layout: fixed;">
	<tr>
		<td> desktop content here </td>
	</tr>
</table>
	
	
	
</body>
</html>

Update:

Tested again on 9th July 2019 and code still works

Works on version 2019.5.26.252424914.release (should work between v8.3.12 and current version noted)

Cheers
