RWD or separate page/site for mobile?

The application that I'm re-writing, which is more interactive-analytic as opposed to content consuming, requires a main screen with a three part view:  a single wide div on the left and two narrower divs on the right (say 67% left, 33% right).  There will be menu presets that will re-size these three divs in relationship to each other (i.e. make one of the two on the right larger), and some drag-resizing after that, and zoom sliders for each window (or at least the left window).

Part of the requirement is that the main screen will be used in interactive group sessions, so the basic div layout needs to stay relatively fixed to maintain a common visual/cognitive view for all participants.  So, no free-floating divs.

Plus there needs to be a lot of little controls within each div, e.g. to click or double click on an element to call up context menus or show information popups.

I can see this basic layout working from a PC down to a 7-inch tablet.   I'm having a hard time imagining that this is going to work in the same basic way on a phone.

=> I don't know that RWD (i.e. Bootstrap) is going to help much, because it's not a matter of content flow (but then, I may be making mis-assumptions about RWD).
=> Phone use would have to rely on browser-provided pinch-and-zoom to be able to effectively read (and interact with) the content of the three divs.
=> It seems like the little controls within each div would have to be configured differently for the phone (i.e. at 48 dp per control they would be too big)
     =>  but maybe pinch and zoom could overcome this.
=> a "pure phone" approach might sacrifice the "3-div view" for viewing each div one at a time, with alerts about when to look at the others (or something like that).
=>  Session participant will also likely be talking on the phone
=>  Phone participants could be given lower text-input capabilities.

On the other hand, webex provides a phone app, so maybe it's possible.  Not sure how much interactivity that has;  I'll have to look into that.

I'm thinking what I need to do is design my app primarily for PCs, take into account the touch orientation of a small tablet, and then make concessions for use on phones where it doesn't cripple the needed analytic/interactive features that are possible at the PC level.  But if the PC/Table design doesn't translated easily to phone, then write a separate GUI for phones.

Any thoughts, suggestions or pointers to articles that would help me think about this would be appreciated.

Thanks!

Here is a good article.

Designing for phone is often a different animal than tablets/phablets

greetings  codequest, , , There are several many "flexible design" frameworks, that can do a good or acceptable div shuffle and size in today's  variations of web device sizes. And there are CSS and javascript methods that you can use to do it yourself. But I found that for some interactive and complex web GUI, that has very many important user inputs (choices), I have to think in design for two or maybe three very different GUI for input sizes and user "view area" with hidden touch to "slide out" info areas like menus. I just can not do that with some automatic div shuffle and size, for instance changing a "three div across" display to a "one div across" display with two hidden touch to "slide outs" divs, , stuck to the right side. For me, sometimes I just have to "write a separate GUI for smaller display size". Unfortunately each one has it's own unique design setup, so there is not "any one size fits all" recommendations.

@mplungam:  Thanks for the input.   That was a good starting point.   Turns out that googling "RWD vs Mobile Site" produced many solid articles on the subject, with many points that spoke directly to my choice.   However, I did not even know to do that search, so the answer above was a help.

@Slick812:  Thanks for the input.  Those detailed implementation issues are a helpful addition to the general research (the comment about "sliding div" was particularly illuminating about the nature of RWD).

So my thinking at this point is that the user experience will be very different for a phone. This is really a business application that will be used by people who work at desks. I believe I can make it work for tablets reasonably well.  But phones are not going to support the many controls and frequent text inputs that are required for full participation.

So the mobile site will become more of a "viewer" site than a "contributor" site, and can wait for release 2.

Again, thanks for inputs, big help.
