HTML | Today I Learned

The output HTML element can be used to show the result or outcome of a calculation.

The idea, apparently, is to mirror input. The example given in the MDN site is:

<form id="example-form">

  <input type="range" id="b" name="b" value="50" /> +

  <input type="number" id="a" name="a" value="10" /> =

  <output name="result" for="a b">60</output>

</form>

The <base> tag can be used to alter all the links and images on the page. It also adds the ability to specify a default target for links. For example:

<head>

  <base href="https://example.com/" target="_blank">

</head>

There's a standard HTML element for adding auto-complete to a text field: datalist.

The <q> element is an "inline version" of the more well-known <blockquote>. Interestingly, the browser will add quotes around it, so that Devs say <q>HTML is hard</q> gets rendered as Devs say “HTML is hard”.
