joomla display module by viewport

Hello.
Can any of the extensions you offer arrange the display of modules according to the viewport? I know Advanced Module Manager can display by device. I don't know exactly how this works, but I often have a problem with it. I am looking for an extension where I can choose the display of the module according to the viewport.
Thank you

And how does it work? Does it really recognize the device or does it follow the viewport? I would need to force this extension to search by viewport...

Good. I understand.
Does Conditional Content work on the same principle? And if I'm not mistaken, in the past I also saw an extension that displayed a template according to the device. Doesn't it exist anymore? I think it was called Template Manager.

And the last question: Do you have an extension that can display different articles by device or viewport from one link in the menu? Or at least part of the page? For example, I have a page that has a lot of desktop effects and graphics. And I want to create a page with the same content, but without ekets and graphics with a minimum of css, smaller images directly for mobile, I can partially create it using Media Query in css. But the page is then twice the size, the browser still pulls the whole thing, but only displays the time. And as a result, the page load time is longer. If the browser could download only the right part when generating the page, it would be great. I thought about trying ReReplacer for that, but it probably won't be easy.

I understand

I will try ReReplacer for that. I will take the page content created in SPPB5 for example. I will duplicate it and modify the duplicate for mobile phone. In this case, the content of the page will be displayed twice. Before and after the part of the page that I want for mobile teleon I will put the ReReplacer tag and do the same for the first part of the content. In ReReplacer, I set the content between these tags to be empty. And finally, I let the tags appear in the code according to the viewport. The result could be that, for example, on a mobile phone joomla starts to generate a page... it encounters a part that is displayed only for the viewport corresponding to the desktop device, thus the rereplacer sees the code between the two tags and replaces it with an empty space. The second half of the article will be visible to mobile because it won't see the ReReplacer tag. And vice versa on the desktop. The result should be that the browser will download and display data for only one part of the page at a time. Unlike a simple media query, where I download all the content and just hide it from the visitor. It is so?

Does Advanced Template Manager have a replacement?

I understand

Hello again.
Thanks to ReReplacer, I managed to solve the responsivity in such a way that I just don't hide the parts of the site with a certain extension (but still I have to download them from the server first and then hide them).
Instead, I tag between the two divs with a special header (so that the rereplacer can easily identify them in the code) and delete everything between those tags.

But what's important is that it doesn't have to download any data for that. If I just hide it with css display: none, the browser downloads the picture from the contacts.

It is the first swallow. I'll try to keep working on it and improve it.

Here's a sample of what it looks like before use:

Here's an example of it working:

And for an idea of ​​the video:

What do you think?

Well, unfortunately. Not working either. I didn't realize that even if I hide the tags for ReReplacer, they will always be there in the code.

How about entering the condition directly for the replacer? using php?
Something like this. But I'm not a programmer so this demo doesn't work.

I understand. My subscription ended a few days ago. I have no problem restoring it once I know the extension can run work based on the viewport.
I will be honest. I don't want to pay $50 to find out they can't.

I wish you a nice Christmas.
