TYPE, START and VALUE are attributes of which tag in HTML?

HTML gives numbering-related attributes only to markup that keeps a running numeric or alphabetic count. Of the list-type elements, only the ordered list — <ol> — maintains such a sequence, so HTML documents the sequence-control attributes type and start on <ol> itself, together with a matching value attribute on its <li> children so a single item can override the running count.

Applied to this item, three numbering-control attributes are involved:

• type — chooses the numbering style (1, A, a, I, or i); defined on <ol>.

• start — sets the number the list begins counting from; defined on <ol>.

• value — used on an individual <li> (only meaningful inside an <ol>) to jump the count to n at that item.

All three exist purely to control the ordered-list numbering mechanism, so reference documentation for <ol> (for example HTML5 Doctor's article "The ol Element and Related Attributes: type, start, value, and reversed") presents them together as the ordered list's attribute set.

<ol type="A" start="3">
  <li>Item C</li>
  <li value="10">Jumps to J</li>
</ol>

This markup validates under the HTML Living Standard and shows all three attributes acting on the same ordered list.

• <ul> renders an unordered, unnumbered list, so it defines none of type, start, or value.

• <dl> renders a description list of <dt>/<dd> term–definition pairs with no numeric sequence at all, so none of the three attributes apply to it either.

• <LL> is not an element defined anywhere in the HTML specification, so it cannot carry any attribute.

Therefore, TYPE, START and VALUE are attributes associated with the <OL> tag — no other offered tag has a numbering sequence for any of them to control.
