wp-login mobile viewport

[bobbravo2]

The wp-login.php page has incorrectly formatted viewport arguments. They should be CSV, not ; separated. In addition, it is impossible for plugins to override this setting, which is why I added the "login_page_viewport" filter to allow 3rd party plugins to specify their own viewport.

Use commas, not semicolons, to separate meta viewport values. props bobbravo2. see #24777.

Bug fixed for 3.6 in [24779], leaving the rest for a future release and further discussion.

My general idea for this patch is to make the login page more accessible, and also allow plugin authors to override the login page viewport. I don't like to disable user scale, as that makes it harder for older people to use the login page, as they cannot zoom in if they have vision impairments.

So to be clear:

• remove user-scalable=0
• make maximum-scale=1.1

Rather than a filter, we would attach an action to login_head and output the meta tag there. But I'm not sure this is necessary for now with a change in the scale?

Seems the least intrusive value for the meta is content="width=device-width" as the whole form is 320px wide. Tested on iPad and Android 4.3 phone. If we need to shrink it a bit so it doesn't have horizontal scroll on older phones (320px width), this can be done better in the css. Also agree with @bobbravo2, don't see a point in limiting the scaling, no need for maximum-scale.

Let's call it wp_login_viewport_meta() and you have yourselves a deal.

Simplify the login page viewport meta for mobile devices, so it's less restrictive on the user. Allows for developers to override if necessary via the login_head action. props azaozz. fixes #24777.
