OKLCH is a perceptually uniform color space — equal lightness values
produce equal perceived brightness across all hues, unlike HSL where
blue at 50% looks much darker than yellow at 50%.
Color scales now output oklch() CSS values directly:
--gray-500: oklch(0.530 0.035 285);
--accent-500: oklch(0.595 0.230 286);
The browser handles gamut mapping natively. Scale definitions in
tokens.edn use [label lightness chroma] tuples where L is 0-1
perceptual lightness, C is chroma (colorfulness), H is hue degrees.
Theme adapter updated: sliders now control OKLCH hue/chroma,
swatches render with oklch() CSS, Copy EDN outputs OKLCH config.
gen.clj includes oklch->srgb and oklch->hex for validation/tools.
Replace hardcoded hex color tokens with algorithmic color scales generated
from HSL parameters. Each scale is defined by hue, saturation, and
lightness steps in tokens.edn, then converted to hex via jon/color-tools.
Color scales (gray, accent, danger, success, warning) generate 11 stops
each (50–950) into :root. Semantic tokens (bg-0, fg-0, accent, etc.)
reference scale variables with var(--gray-50), var(--accent-500), etc.
Dark theme switches which stop each semantic token points to.
Gray scale uses hue 240 with tapered saturation for a purplish tint
matching the activity-tracker aesthetic. Accent is vivid purple (hue 252).
Border radii bumped to 6/10/16px for a rounder feel.
To shift the entire palette (e.g. warm gray), change hue/saturation in
tokens.edn and run `bb build-theme`.
- Add universal box-sizing: border-box reset to base styles
- Make alert component responsive with container queries (flex-wrap,
full-width title/body at narrow widths)
- Increase form legend margin-bottom from --size-1 to --size-3
Instead of rendering error messages as `<small class="form-error">`
below inputs, errors now display as a circle-x icon inside the input
area. Hovering the icon shows the error text in a danger-styled tooltip.
- Wrap children in `.form-field-control` when error is present
- Use existing tooltip + icon components for the error indicator
- Add CSS for positioning, padding-right offset, and danger color overrides
- Update tests to match new structure
- Add pre-commit tmux server check instructions to AGENTS.md
<legend> elements have special rendering behavior inside <fieldset>
that doesn't participate properly in flexbox gap. Change
margin-bottom from 0 to var(--size-1) on .form-fieldset--inline
.form-legend to add visible spacing.
`a.btn` had `color: inherit` which overrode variant-specific colors
(e.g. `--fg-on-accent` on `.btn-primary`) due to higher specificity
(element+class > class). This caused black text on primary link buttons
in light mode. Let variant classes control text color instead.
Add a `[data-no-transitions]` CSS rule that suppresses all transitions.
The theme toggle in all three dev targets (hiccup, replicant, squint)
sets this attribute before switching, then removes it on the next
animation frame, preventing the jarring animated color shift.
Adds a general-purpose icon system (ui.icon) with inline SVG rendering:
- 50+ icons from the Lucide icon set (navigation, actions, objects, UI,
status, dev/technical categories)
- Size variants: sm (--size-4), md (--size-5), lg (--size-6), xl (--size-8)
- Pure data approach: icon paths stored as hiccup vectors, rendered into
SVG with stroke="currentColor" so icons inherit text color
- API: (icon/icon {:icon-name :home :size :lg :class "custom"})
Integrates icons into the sidebar component:
- sidebar-menu-item now accepts :icon-name prop
- Renders icon in a .sidebar-menu-item-icon wrapper at :sm size
All three dev targets updated with icon gallery demo and sidebar icons.
Add global :focus-visible outline style and migrate form components
from :focus box-shadow to :focus-visible outline. Refactor accordion
chevron from CSS ::after pseudo-element to explicit span element.
Children were appended to the outer <details> element instead of inside
the .accordion-content div, causing text to render outside the accordion
box. Also adds .accordion-group wrapper to eliminate parent gap between
stacked items, and styles content with smaller font and muted color.
Refactor card to use flex column with gap-based spacing instead of
per-section padding, tightening the space between header, body, and
footer from size-6 to size-3. Add .card-footer .btn override to
render buttons at font-base size.
When :href is provided, the button renders as <a> instead of <button>,
enabling navigation links with full button styling.
New :link variant renders as a minimal text link (underlined, accent
color, no background/padding) — works as both <button> and <a>.
CSS includes reset styles for a.btn (removes default link decoration)
and preserves underline for a.btn-link.
The triangle's `bottom` offset was too large, leaving a visible gap
(and 1px sub-pixel seam) between the arrow and the tooltip body.
Changed from `calc(100% - 5px)` to `calc(100% - 1px)` so the arrow
slightly overlaps the box, eliminating the gap.
Add click handlers to the dialog component for all three targets that
close the dialog when clicking the backdrop area (outside the dialog box).
Uses event.target === event.currentTarget to distinguish backdrop clicks
from content clicks.
- :clj — inline onclick attribute
- :cljs — Replicant :on {:click handler}
- :squint — :on-click handler
- CSS: cursor: pointer on ::backdrop for affordance
Components (.cljc + .css + tests):
- Alert (success/warning/danger/info variants)
- Badge (primary/secondary/outline/success/warning/danger)
- Card (card/card-header/card-body/card-footer)
- Accordion (collapsible with open/closed state)
- Table (headers/rows, striped/bordered variants)
- Dialog (modal with header/body/footer sections)
- Breadcrumb (nav with active item)
- Pagination (current/total with prev/next)
- Progress (value bar with color variants)
- Spinner (sm/md/lg sizes)
- Skeleton (line/box/circle/heading placeholders)
- Switch (toggle with checked/disabled states)
- Tooltip (hover text via data-tooltip attr)
CSS-only additions:
- Form elements (inputs, selects, checkboxes, radios, range, groups)
- Grid (12-column system with offsets, responsive)
- Utilities (flex, spacing, alignment, sr-only)
Also adds warning/fg-on-warning tokens to light and dark themes.
All 3 dev targets updated with full component showcase.
40 tests, 213 assertions, all passing.
Add :scales config to tokens.edn with two generated scales:
- Size (linear): --size-1 through --size-16, base 0.25rem × N
- Font (geometric): --font-xs through --font-3xl, ratio 1.25
gen.clj computes values and emits them into :root only (not dark
theme blocks). button.css now uses scale vars instead of raw rem.
Change base or ratio in tokens.edn to recompute the entire scale.
- Rename CSS classes from BEM double-dash (btn--primary) to flat
utility-style single-dash (btn-primary)
- Move button CSS from inline Clojure string in gen.clj to
src/ui/button.css next to button.cljc
- gen.clj now auto-collects all src/ui/*.css files via babashka.fs glob
- Replace clojure.java.io with babashka.fs throughout gen.clj
- Update AGENTS.md to reflect new conventions
Move font-family, background, color, margin, and transition from
duplicated inline <style> blocks in each dev target into the CSS
generator (base-css). Dev pages now only set page-specific padding.
Also fixes hiccup target rendering the wrong font due to hiccup2
HTML-escaping quotes inside <style> tags, and adds missing <!DOCTYPE>.
