Presentation Styling

Reference CSS classes and HTML patterns for presentation components.

Installation

  1. Make sure Claude is on your device and in your terminal.

    Skills load from ~/.claude/skills/ when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then run claude in any terminal to verify.

    One-time setup
    npm i -g @anthropic-ai/claude-code

    Already have it? Skip ahead.

  2. Paste into Claude Code or into your terminal.
    Install

    This copies the whole skill folder into ~/.claude/skills/presentation-styling-shanraisshan/ — the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.

    Faster alternative (instruction-only skills)

    Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.

  3. Restart Claude Code.

    Quit and reopen Claude Code (or any other agent that loads from ~/.claude/skills/). New skills are picked up on startup.

  4. Just ask Claude.

    Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

Prefer to read the source first? Open on GitHub.

What this skill does

Presentation Styling Skill

CSS classes and HTML patterns used in presentation/index.html.

CSS Component Classes

Layout

  • .two-col — 2-column grid layout with 24px gap
  • .info-grid — 2-column grid for info cards
  • .col-card — Card inside a column (add .good for green border, .bad for red border)
  • .info-card — Card in an info grid

Content Blocks

  • .trigger-box — Gray box with dark left border (for key concepts, prerequisites)
  • .how-to-trigger — Green box with green border (for "Try This" actions)
  • .warning-box — Orange box with warning border (for important warnings)
  • .code-block — Dark code display block with monospace font

Lists

  • .use-cases — Container for icon+text list items
  • .use-case-item — Individual item with icon and text
  • .feature-list — Simple bordered list

Tags & Badges

  • .matcher-tag — Gray inline pill tag
  • .weight-badge — Green pill badge (auto-injected by JS for weighted slides)

Code Block Syntax Highlighting

Inside .code-block, use these spans for syntax coloring:

<div class="code-block">
<span class="comment"># This is a comment</span>
<span class="key">field_name</span>: <span class="string">value</span>
<span class="cmd">&gt;</span> command to run
</div>
  • .comment — Green (#6a9955) for comments
  • .key — Blue (#9cdcfe) for property names/keys
  • .string — Orange (#ce9178) for string values
  • .cmd — Yellow (#dcdcaa) for commands/prompts

Slide Type Patterns

Content Slide with Two Columns (Good vs Bad)

<div class="slide" data-slide="N" data-weight="5">
    <h1>Title</h1>
    <div class="two-col">
        <div class="col-card bad">
            <h4>Before (Vibe Coding)</h4>
            <!-- bad example -->
        </div>
        <div class="col-card good">
            <h4>After (Agentic)</h4>
            <!-- good example -->
        </div>
    </div>
</div>

Do not hardcode <span class="weight-badge"> in slide HTML. The presentation JavaScript injects and removes weight badges automatically.

Content Slide with Code Example

<div class="slide" data-slide="N">
    <h1>Title</h1>
    <div class="trigger-box">
        <h4>Key Concept</h4>
        <p>Description</p>
    </div>
    <div class="code-block"><span class="comment"># Example</span>
<span class="key">field</span>: <span class="string">value</span></div>
</div>

Icon List Pattern

<div class="use-cases">
    <div class="use-case-item">
        <span class="use-case-icon">EMOJI</span>
        <div class="use-case-text">
            <strong>Title</strong>
            <span>Description text</span>
        </div>
    </div>
</div>

Journey Bar Specific

  • .journey-bar — Fixed bar below progress bar
  • .journey-bar.hidden — Hidden on title slide
  • Journey bar color transitions from red (0%) to green (100%) via HSL interpolation
  • Weight badges are auto-injected by JS into h1 elements of weighted slides
