# Timeline Creator
Create interactive HTML timelines and project roadmaps with Gantt charts and milestones.
## When to Use
- "Create timeline for [project]"
- "Generate roadmap for Q1-Q4"
- "Make Gantt chart for schedule"
- "Show project milestones"
## Components
1. **Timeline Header**: project name, date range, completion %
2. **Phase Groups**: Q1, Q2, Q3, Q4 or custom phases
3. **Timeline Items**: tasks with start/end dates, progress, status
4. **Milestones**: key deliverables with dates
5. **Gantt Visualization**: horizontal bars showing duration
## HTML Structure
```html
<!DOCTYPE html>
<html>
<head>
<title>[Project] Timeline</title>
<style>
body { font-family: system-ui; max-width: 1400px; margin: 0 auto; }
.timeline-bar { background: linear-gradient(90deg, #4299e1, #48bb78); height: 20px; border-radius: 4px; }
.milestone { border-left: 3px solid #e53e3e; padding-left: 10px; }
/* Status colors: #48bb78 (done), #4299e1 (in-progress), #718096 (planned) */
</style>
</head>
<body>
<h1>[Project] Timeline</h1>
<!-- Phase sections with timeline bars -->
<!-- Milestones list -->
</body>
</html>
```
## Timeline Bar Pattern
```html
<div class="timeline-item">
<span>Task Name</span>
<div class="timeline-bar" style="width: [percentage]%; background: [status-color];"></div>
<span>[start] - [end]</span>
</div>
```
## Workflow
1. Extract tasks, dates, phases from project
2. Calculate duration percentages
3. Group by phases (quarters or custom)
4. Create HTML with Gantt-style bars
5. Add milestones section
6. Write to `[project]-timeline.html`
Use semantic colors for status, keep layout responsive.Want a live grade + an embeddable README badge? Run your skill through the free scanner.
Graded independently by Skillproof — nothing to sell the author. Quality is mechanical + corpus-grounded; safety flags are heuristic (builtin+triage), not a malicious verdict.
