Is missing text on mobile page considered hidden text?

[JudgeJeffries]

I'm in the process of making an important website mobile friendly. The layout is nav bar on the LHS, central text area in the middle and contact form on the RHS. As screen size reduces the form initially disappears. As screen size reduces further the nav bar disappears leaving just the central text area visible.
This arrangement satisfies Google when I run it through their mobile friendly test page.
My question is, after the nav bar disappears, as happens on mobile phone screens, leaving only the central text area visible would the missing nav bar be considered as hidden links?

No. It's common practice for significant page elements to be set to 'display:none' using media queries for smaller displays. However, for usability, I'd think it would be worthwhile to look for methods that allow mobile users to see this navigation area with some kind of show/hide toggle button.

Naahh.

Does it really disappear, or just jump to the bottom? If the latter, there's no "hidden text" issue. It is just not initially visible.

Tangor,
Its set so the form and nav bar totally disappear. The central text panel has telephone and email contact details and each page is so individual that people go not really need to wander off to onto other pages to get the information they need.
The form and/or nav bar do not go to the bottom as screen size reduces and unless there's a hidden text issue I'm not inclined to show them as screen size reduces.Usability issues aside is there any possibility that the disappearing form and nav bar menu could be considered to be hidden text.

I doubt there is a problem, as these are nav issues and not content. Until something is said otherwise, I wouldn't worry about it. Meanwhile, is there any reason you don't serve the proper size upon viewport?

Google does this themselves on YouTube.

Go to the homepage with a browser at least 1260 pixels wide and find the div with the id "guide-container". It's the nav menu on the left hand side with entries like "What to Watch", "My Channel", "Subscriptions", etc.

The css visibility atrribute is "visible" until you go narrower than 1260 pixels, at which point it changes to "hidden", and you have to click the menu icon to see it again.

Number one tip as far as mobile is concerned in my opinion.

If we do not need information on the mobile then why would we need it on the desktop? Because websites are now designed "mobile first" we need think about interface design from this new perspective.

Depends on site niche. In many eCom niches mobile is just a start of the funnel and the funnel is completed on the desktop. People do not use both in the same way.

For many things I may do a quick search on the mobile if I am away from the desktop, but for more serious study I prefer desktop. I expect desktop version to have more details than mobile. In fact I feel that when the site is designed with mobile in mind first, and I am viewing it on the desktop, it often lacks extra information and utility I would expect from a desktop site.

So for some things mobile first makes a perfect sense. But for some other it does not.
