@LeonMatthes as mentioned in Jira, can we drop doxybook2 and use the current CSS that other repos use?

Hi @dantti , I have to say I very much like the current documentation, it just appears very modern.
But alas, doxybook is abandoned, so we'll need to move on at some point anyway.

Can you share an example of how the resulting documentation will look?
Which of our existing projects are using the new CSS that you mentioned?

[dantti]

this is what most KDSomething are using https://kdab.github.io/KDSingleApplication/

I'll do a PR changing this then you can build locally and see if it pleases you

[dantti]

PR rebased result -> https://kdab.github.io/KDBindings/ once this is merged I'll remove my branch from the ones that are allowed to deploy so only what's in master will trigger a deploy

[dantti]

hmm seems we are both pushing :)

[LeonMatthesKDAB]

Small nitpick, then we can merge :)
