Loading

aria-busy="true" on almost any element shows a spinner before its content; on buttons and links it also blocks the pointer.

Usage

<button aria-busy="true">Saving…</button>
<button aria-busy="true"></button>       <!-- spinner only -->
<article aria-busy="true">Loading…</article>

The spinner is --v-icon-loading (1em); empty busy elements center it. Form controls (input, select, textarea) and form / html are excluded. Because the state is an attribute, a Quark rule sets it from any fact: button { aria-busy: ternary(attr("is-loading") != null, "true", none); } or provider-fetch[is-loading] button { aria-busy: "true"; } (with its inverse).

Beta. The Nucleus Stack is in beta for a few weeks until features are stabilized and optimized.
