The `TimelineItem` component is used to display items on a vertical timeline, connected by `TimelineItem-badge` elements.

```html live
<div class="TimelineItem">

## TimelineItem-badge

The default TimelineItem-badge color is dark text on a light gray background.

### Adding color to TimelineItem-badge

To have color variants, use the [color utilities](/utilities/colors) on the badge. Be cautious with color choices. We typically use them in the timeline to give meaning to the event in context of the timeline.

## TimelineItem--condensed

TimelineItem has a condensed variant that will reduce the vertical padding and remove the background from the badge item. These are most commonly used in commits.

```html live

## TimelineItem-avatar

Sometimes you want to give ownership to an event by displaying an [Avatar]() of the author. To do this, you'll need to wrap the TimelineItem in a `<div>` and give it space for the avatar. `ml-6 pl-3` This is `40px`, the size of the image, and `16px` space for the gutter.

```html live
<div class="ml-6 pl-3">
  <div class="TimelineItem">
    <div class="TimelineItem-avatar">
      <img class="avatar" height="40" width="40" alt="@octocat"

## TimelineItem-break

To create a visual break in the timeline, use `TimelineItem-break`. This adds a horizontal bar across the timeline to show that something has disrupted it. Usually this happens when a close or merged event occurs.
