Hard to find this, I have been playing with a few including Redsy. What I'm looking for is:
A responsive theme that also works across various mobile platforms.
That includes the ability to change the colour scheme so it's congruent with a web site (not SMF) that sits on top of the forum.
Or at least in which the css is easy to edit to change the colours. I unfortunately found editing the css colour scheme in Redsy is a complex nightmare. (Not bagging Redsy in general, it's a great scheme).
Do we have a theme here that fits the above requirements?
I have tried it mostly in local but it seems to have a very good base is the theme called TEMiZ (https://custom.simplemachines.org/themes/index.php?lemma=2879)
Regards!
Find a color changing theme, look how they do it... then you can do the same thing on almost any theme.
That's what I did with fx-sabers.com/forum - I used the studio003 theme from bloc as a baseline and then added the alternate css definitions and a form for users to pick.
