SpiderBasic

I am not familiar with nowadays design concepts but i would consider this a "fluent web page":

https://play.google.com/googleplaygames

The ScrollBar at the right only partially commands the content of the page: basically it represents a section grouping in which design elements can freely be replaced, resized or animated beyond static design approach methods.

Could we please talk about that? I suppose it would be hard too do such thing with SpiderBasic but it is exactly where the web is going to right now. Sooner or later we will all ask for this.

(Please call up the link and scroll far down or you will hardly have a chance to guess what this is about)

In html/css level this is s static div or an iframe(iframe= html div =css)

In spider basic i guess the easiesy aproach is with framegadget
Which can have this "grouping"

Hi,

I've looked at the website you'd linked from my desktop browser.

The ScrollBar at the right only partially commands the content of the page ...

I think I get what you mean. What you have to keep in mind, is the following:
What you've linked, is a webpage made by one of the leading tech companies in the world. One that even influences the way we experience a part of the web today, or influences the programs we experience the web with (talking about Chrome browser and Web standards here).

The page is a presentation. It's a commercial. It tries to get you into using some of the offered services (and have you pay - with money or data/privacy in the end). Of course it comes up with all the fancy and eye-candy possible.

We can talk about this, sure.
The 'web' - and some of us are here on the web since several decades - has so many faces. This is one way, not the way. Imagine the following: Would you rather read a longer Wikipedia article in that form of presentation? I doubt that.
Is it appropriate for displaying media, like looking at movies, records or games (on SteamDeck)? It might, yes. Could I imagine having such a presentation in Kodi? Why not?
Would I like that fancy when writing here? No.

It would be hard to rebuild that whole site in SpiderBasic, yes. But so would it be to rebuild the whole site in Latex.
SpiderBasic - in my experience - relies on existing, stable frameworks/technologies to provide us the means to create WebApps and WebGames with a certain amount of business logic.

It might simply be not the right tool for the task you are talking about.

It is possible with SB, but it will need a lot of work in mixing SB und JS, and I don't see any use case for it from SB...

You simply need to modify the html-dom objects from SB using JS, for example I've made an SB app using the Bootstrap CSS framework with its definition of cards and form elements, using some SB procedures that modify the html code that is shown in the app.
