conditional control of colours in decoration frames?

[GerardFalla]

I've a situation where our client's expectation is for coloured page edges in both printed output and online output which will change based on target audience, as will the actual in-topic content.

The content part is clearly manageable through condition tags - my query to the community is whether I can control the background colour of decoration frames in a page layout set either via CSS or via condition tags or both, or more correctly, what would be best practise?

I can't immediately see how to accomplish this in a true elegant single-source methodology, though clearly I could set up multiple versions of each page layout with the requisite colours and simply set up multiple targets, each calling the relevant page layout, however that seems like brute-force rather than correctly single-sourced thought: is there a better, more elegant method out there in use for this circumstance?

Thanks,

Soooo... checking back in on this topic: I had had a suggestion from the very helpful Michal Skowron via slack to use snippet conditions and tables nested into another snippet, and so I tried this approach out, fairly extensively.

I had some initial success, and a lot more failures... but crucially I was having trouble getting snippet conditions to behave as expected reliably.

I was then considering going back to the higher overhead, less single-sourced but more reliable path of have massively parallel multiple page layouts - all the same save the audience colour bars.

However, I've now come up with a different approach: I'm going to establish a slightly convoluted workflow which will at least allow a kind of single-sourced control over these page layout elements: I will set them up in Affinity Designer (direct equivalent to Illustrator but cheaper and faster) and use saved styles to manage the elements' appearances, export out the page layouts as individual EPS files, place those into image frames on the Flare Page Layouts - this way we've one place to control and update page layout elements, aiding both in time saved and consistency - admittedly there's some overhead in the export / import process, but this modus operandi is far preferable to dozens of parallel edits inside Flare's Page Layout tools, which are not very precise IMHO.

If anyone else has any success, or specific advice on nested snippets with snippet conditions being used to carry decoration frames to allow for per-audience layout control from a single set of page layouts controlled via those conditions at the target, please do let me know, as I think that would be the best case - if I could get it to work!

Thanks all who weighed in, both here and in Flare's slack community.
