In general, this is a styling problem, and one that's not too hard to
address in CSS using :target.  Make your tabs an <a href=#card1>,
pointing to <div class=card id=card1>.  This isn't perfect, though -
you can't target the current tab (though there's been suggestions for
a pseudo to match links that match the current page and/or target,
which may hit Selectors 4), and it's difficult to target a particular
tab to be open on page load.

An alternate idea with some potential is to combine <details> with
Template Layout.  Something like:

<details open>
  <summary>foo</summary>
  FOO
</details>
<details>
  <summary>bar</summary>
  BAR
</details>
<style>
body {
  display: template( "a" /min-content "b" /* );
}

body > details {
  position: slot(b);
}

body > details > summary {
  position: slot(a);
}

body > details[open] > summary {
  font-weight: bold;
  /* other "current tab" styling */
}
</style>

Not sure of the semantics there, but it has potential, given the
current lack in CSS to duplicate the functionality properly.
