Hi, I’d say that very much depends on what you give them. A site that relies on Layouts and Blocks would make that easy even without any PHP knowledge.
But your question is a bit too broad to answer. If your clients want to create templates etc. they require Kirby and PHP knowledge.
Please note that the language in this forum is English only.
Foe example its possible that a user get a lsndingpage with sliders, carousels and more components and can start with a plain kit of kirby, if the user know just html and css and not php?
Oe for example if the site is ready bur the user wants somethin extra vuild on the homepage like a slider or something like that?
You cannot build a site with Kirby with just HTML and CSS, you need to learn how to use Kirby, which requires at least some basic PHP and a willingness to learn how to use Kirby (docs, videos etc.)
As I already wrote above, a site can be set up with building blocks (layout field and default/custom block types, so that it is easy for users to add these building blocks to their pages and fill with content. The more of these building blocks you create, the less likely it is that a user will need a developer when adding new stuff.
But Kirby is not WordPress and that is by purpose, so you cannot simply add thousands of plugins from the control panel to achieve something.
