html-style

Transform barebones HTML into styled output using a specific design system.

Workflow

Read the user's HTML
Identify elements to style (tables, lists, status text, buttons, sections)
Inject <style> block from assets/base.css
Add appropriate classes to HTML elements
Add interactive JS if needed (copy buttons, drafts, collapsible sections)

Element Styling Rules

Tables

Default: minimal borders, no hover
Add .table-styled for: hover effect, .positive/.negative cell colors, .highlight rows
Sortable: add th.sortable with <a href="?sort=col">Col ▼</a>

Status Indicators

Text status (.stale/.warm/.pending): Use for inline status in sentences
Status pills (.status-*): Use for badge-style indicators, typically with icon (✓ ✗ ◷)
Trends (.trend-up/.trend-down): Use for numeric changes, adds arrow automatically

Sections

Use .section-header with emoji prefix for visual breaks:

<div class="section-header">🔴 URGENT</div>
<div class="section-header">🟠 PENDING</div>

Interactive Elements

When HTML has drafts or copy buttons, add this JS:

function saveDraft(el) {
    localStorage.setItem('draft:' + el.dataset.threadId, el.textContent);
}
function copyToClipboard(text, btn) {
    navigator.clipboard.writeText(text).then(() => {
        btn.textContent = 'Copied!';
        setTimeout(() => btn.textContent = 'Copy', 1500);
    });
}

Theme

Default: Light (background: #fff)
Dark mode: Add class="dark" to <body> when user requests dark theme or context is trading/real-time

Compatibility with Structure Skills

When styling output from quick-view or table-filters, these class mappings apply:

quick-view classes

Their Class	Style As
`.type-user`	`.status-pending` (blue border)
`.type-draft`	`.status-pending` (orange border)
`.type-done`	`.status-success` (green border)
`.source`	Already styled (muted, small)
`.meta`	Already styled (muted header)
`.actions`	Inline button group

table-filters classes

Their Class	Style As
`.filter-bar`	Flex row with gap
`.filter-chips`	Inline chip container
`.chip`	Dark pill with `.chip-remove`
`.filter-menu`	Dropdown panel (`.filter-menu`)
`.empty-state`	Centered, muted text

The base.css includes styles for these classes automatically.
