Hatch (https://hatch.one) has many of the characteristics of HyperCard plus its "projects" are full featured, shareable and remixable (if you want) web pages.

- Easy drag-and-drop interface with a library of images, audio, video, etc.

- Programmable with Visual Scripting for an easy on ramp to adding logic and behaviors.

- Programmable with Javascript if that's what you want to learn.

- HTML "components" if you want to dig into HTML, CSS and all that good stuff.

- A few tutorials to help get started with physics, animation, etc.

- Free.

- Super fun! Ok, I'm highly biased as one of its creators.
