You can with DSD.

You can’t. At minimum you need to call customElements.define().

  • You absolutely can. It's the primary purpose of the DSD (Declarative Shadow DOM), one of the many new specifications people complain incessantly about.

      <my-component>
        <template shadowrootmode="open">
          <style>
            ::slotted(*) {
              font-weight: bold;
              font-family: sans-serif;
            }
          </style>
          <slot></slot>
        </template>
        <p>content</p>
      </my-component>
