a11y(2.5.8): chip — pad remove button to 24×24 CSS px minimum by rosanusi · Pull Request #3544 · temporalio/ui

rosanusi · 2026-06-11T17:30:23Z

Description

The chip remove button (<button><Icon name="close" /></button>) had no padding and no explicit size, so its hit area collapsed to ~16×16 CSS px — below the WCAG 2.5.8 (Target Size Minimum, Level AA) requirement of 24×24.

Fix: add inline-flex items-center justify-center p-1 to the button's class. p-1 is 4 px each side, expanding the hit area to exactly 24×24 (4 + 16 + 4). The visible close icon is unchanged; merge() is already imported in the file. The button's disabled ? 'hidden' : '' hide behaviour is preserved.

The IconButton approach (recommended in the audit issue) was considered but deferred: chip.svelte is already in Svelte 5 runes mode while icon-button.svelte is Svelte 4 — Button explicitly types onclick as never, and using on:click syntax in a runes component triggers deprecation warnings. The padding approach satisfies 2.5.8, has zero interop risk, and keeps the diff minimal. A follow-on migration to IconButton can happen as part of the broader Svelte 5 component migration.

Changed file: src/lib/holocene/chip.svelte — 4 lines added to the remove button's class.

This fix cascades to all Chip consumers in both ui-main and cloud-ui-main (via the @temporalio/ui tarball).

Screenshots

No visual change — close icon stays 16×16 px; padding is transparent. Hit area grows from ~16×16 to 24×24.

Design

No design changes. The chip's outer min-h-7 (28 px) container accommodates the 24-px button height with 2 px headroom each side.

Testing

Visit the workflows list with active filter chips visible.
Inspect the chip remove button in DevTools: confirm computed size is 24×24 px.
Tap-test on a touch device: confirm reliable activation without accidentally hitting adjacent chip content.
Keyboard Tab to the remove button, press Enter/Space — chip is removed.
Focus-visible ring is visible on the remove button.
axe-core: no target-size violations on chip remove buttons.
Visual regression: chip layout unchanged across filter-bar, search-attribute filter list, chip-input, and combobox chip variant.

Checklist

No new i18n keys
No visual change to icon or chip container
Cascades to cloud-ui-main via @temporalio/ui tarball

Docs

No documentation changes required.

A11y-Audit-Ref: 2.5.8-chip-remove-button

The remove button rendered at ~16×16 px (bare Icon, no padding), falling below the WCAG 2.5.8 24×24 minimum. Adding p-1 (4 px per side) expands the hit area to exactly 24×24 while keeping the visible close icon unchanged. inline-flex items-center justify-center ensures the icon stays centred within the enlarged target.

@rosanusi just FYI the PR statement is incorrect about two things:

There IS a visual change, though minor:

Before:

After:

Explanation:

The icon itself never changed (16×16). Everything below flows from p-1 (4px padding on every side) making the button bigger, which then ripples out to the chip because the chip is sized to its contents.

Width: 85 → 93px (+8px)

The remove button was just the bare 16px icon (padding: 0). p-1 adds 4px left + 4px right → button width becomes 4 + 16 + 4 = 24px. That's +8px of button width.

The chip is w-fit (shrink-to-fit) and lays its children out in a row, so the chip's width is the sum of its children. An 8px-wider button means an 8px-wider chip. The label and the inter-item gap-1 are unchanged, so the increase passes straight through: +8px.

Height: 33 → 36px (+3px)

The chip's height = (tallest child) + its own vertical padding. The chip has p-1.5 = 6px top + 6px bottom = 12px.

Before: the two children were the label text and the button. The label's line box is text-sm (14px) × leading-[1.5] ≈ 21px; the button was 16px. Tallest = 21px (the text). Chip = 21 + 12 = 33px.

After: p-1 makes the button 4 + 16 + 4 = 24px tall. Now the button (24px) is taller than the text line (21px), so it becomes the tallest child. Chip = 24 + 12 = 36px → +3px.

So the height grew not because the chip's padding changed, but because the padded button overtook the text as the tallest item in the row.

Why min-h-7 didn't absorb it

The PR assumed the chip sits at min-h-7 (28px) with room to spare for a 24px button. But min-h-7 is a minimum, not a maximum — the chip's natural height (33px before, 36px after) already exceeds 28px, so that rule never engaged and couldn't cap the growth.

(inline-flex items-center justify-center is a secondary effect: it centers the 16px icon inside the now-24px box and removes any inline whitespace, but the padding is what drives the size change.)

Testing instructions are wrong.

"Visit the workflows list with active filter chips visible. Inspect the chip remove button: confirm 24×24."

But the "filter chips" on the workflows list are not that component. Tracing the render path, the workflows filter bar (filter-list.svelte:104) builds its active-filter pills from DropdownFilterChip and StatusFilterChip, which are Button-based dropdown pills (chevron ▾, click-to-edit) — they have no × remove button and no .chip markup at all.

holocene/chip.svelte only renders through ChipInput and combobox (multiselect). The most direct route:

/namespaces/default/workflows/start-workflow → Search Attributes → Add a search attribute, set its type to "Keyword List" → the value field becomes a chip input; each entered value renders a real Chip with the enlarged × remove button.
