Totally agree. I've been working on a programming language for UI designers, but it's been years and I doubt I'll ever release it at this point. The idea was to offer a syntax that conforms to their vocabulary and mental models. So if you were designing a button:

  elements
    shape Wrapper
      text Label

  style Wrapper
    fill: blue

  style Label
    content: Click Me
    fill: white

edit: no harm in sharing the demo page that I never released. Warning - it's very broken. But it kinda works: https://matry.design/demo
