15 Mar 202423 minutes to read

You can customize the Timeline items dot size, connectors, dot borders, dot outer space and more to personalize its appearance. This section explains the different ways for styling the items.

Connector styling

Common styling

You can define the styles applicable to the all the Timeline item connectors.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const dailyRoutine: TimelineItemModel[] = [
  { content: 'Eat' },
  { content: 'Code' },
  { content: 'Repeat' }
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: dailyRoutine,
  cssClass: 'custom-connector'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");

    <div id='container' style="height: 250px;">

    </div>
    <style>
        .custom-connector .e-timeline-item.e-connector::after {
            border-color: #f7c867;
            border-width: 1.4px;
        }
    </style>
</body>
</html>
#container {

    height: 40px;

    position: absolute;
    top: 45%;
    width: 30%;
}

Individual styling

You can also apply unique styles to individual connectors, to differentiate specific items within the Timeline.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const dailyRoutine: TimelineItemModel[] = [
  { content: 'Eat', cssClass: 'state-initial' },
  { content: 'Code', cssClass: 'state-intermediate' },
  { content: 'Repeat' }
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: dailyRoutine,
  cssClass: 'custom-connector'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");

Dot styling

Dot color

You can modify the color of the dots to highlight the specific Timeline items.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const orderStatus: TimelineItemModel[] = [
  { content: 'Ordered', cssClass: 'state-completed' },
  { content: 'Shipped', cssClass: 'state-progress' },
  { content: 'Delivered' }
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: orderStatus,
  cssClass: 'dot-color'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");

        .dot-color .state-completed .e-dot {

    position: absolute;
    top: 45%;
    width: 30%;
}

Dot size

You can adjust the size of the dot to make it larger or smaller by using the --dot-size variable.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const dotSizes: TimelineItemModel[] = [
  { content: 'Extra Small', cssClass: 'x-small' },
  { content: 'Small', cssClass: 'small' },
  { content: 'Medium', cssClass: 'medium' },
  { content: 'Large', cssClass: 'large' }
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: dotSizes,
  cssClass: 'dot-size'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");

    left: 45%;
    position: absolute;
    top: 45%;
    width: 30%;
}

Dot shadow

You can add shadow effects to the Timeline dots to make it feel visually engaging by using the --dot-outer-space & --dot-border variables.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const orderStatus: TimelineItemModel[] = [
  { content: 'Ordered' },
  { content: 'Shipped' },
  { content: 'Delivered' }
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: orderStatus,
  cssClass: 'dot-shadow'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");

    position: absolute;
    top: 45%;

}

Dot variant

You can achieve the desired dot variant by customizing the border, outline and background colors of the Timeline dots.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const dotVariants: TimelineItemModel[] = [
  { content: 'Filled', cssClass: 'dot-filled' },
  { content: 'Flat', cssClass: 'dot-flat' },
  { content: 'Outlined', cssClass: 'dot-outlined' }
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: dotVariants,
  cssClass: 'dot-variant'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");

        .dot-variant .dot-outlined .e-dot::before { content: 'C';}
        
        .dot-variant .dot-filled .e-dot {
            background: #33cc33;
            --dot-outer-space: 3px;
            outline-color: #81ff05;
            --dot-size: 25px;
        }
        .dot-variant .dot-flat .e-dot {

            --dot-size: 25px;
            --dot-radius: 10%;
        }
        .dot-variant .dot-outlined .e-dot {

            --dot-outer-space: 3px;

    height: 40px;
    left: 45%;
    position: absolute;
    top: 45%;
    width: 30%;
}

Dot outline

By adding the e-outline class to the Timeline cssClass property, it enables the dots to have an outline state.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const orderStatus: TimelineItemModel[] = [
  { content: 'Shipped'},
  { content: 'Departed'},
  { content: 'Arrived'},
  { content: 'Out for Delivery'}
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: orderStatus,
  cssClass: 'e-outline'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");
