The rule

A timeline component needs a main container.

This container holds all timeline elements. Specific CSS classes control the layout and appearance of the timeline.

The main container for a timeline is the `.timeline` class. This class holds all parts of the timeline. Do not use `.timeline-vertical` as the main container. That class is for a different visual style. The `.timeline::before` pseudo-element creates the vertical line. This line has a gradient effect. It is positioned absolutely to the left. A `.timeline-marker` shows a point on the timeline. It is positioned to the left of the main content. Its position must be outside the main timeline padding. The `.timeline-time` class is optional. A developer uses it for dates or times. Each item in the timeline is a `.timeline-item`. The last item does not have a bottom border.

A developer is building a website feature to show project history. The developer uses the `.timeline` class for the main container. Each project milestone is a `.timeline-item`. A `.timeline-marker` shows each milestone point. This structure ensures the timeline displays correctly.
