    flex-direction: column;
    position: relative;
    margin: 40px 0;

    padding-right: 30px;
    position: relative;
    margin: 10px 0;
    width: 50%;

.timeline-item:nth-child(odd) {
    align-self: flex-end;
    justify-content: flex-start;
    padding-left: 30px;
    padding-right: 0;

    transform: rotate(45deg);
    width: 15px;
    height: 15px;
}

.timeline-item:nth-child(odd) .timeline-item-content {
    text-align: left;
    align-items: flex-start;
}

.timeline-item:nth-child(odd) .timeline-item-content::after {
    right: auto;
    left: -7.5px;
    box-shadow: -1px 1px 1px rgba(0, 0, 0, 0.2);

.timeline-item-content p {
    font-size: 16px;
    line-height: 24px;
    margin: 15px 0;
    max-width: 250px;
}

.timeline-item-content a {
	color: #333;
	text-decoration: none;
    font-size: 14px;
    font-weight: bold;
}

.timeline-item-content a::after {
    content: ' ►';
    font-size: 12px;
}

.timeline-item-content .circle {
    background-color: #fff;
    border: 3px solid #e17b77;
    border-radius: 50%;
    position: absolute;
    top: calc(50% - 10px);
    right: -40px;
    width: 20px;
    height: 20px;
    z-index: 100;
}

.timeline-item:nth-child(odd) .timeline-item-content .circle {
    right: auto;
    left: -40px;
}

@media only screen and (max-width: 1023px) {
    .timeline-item-content {
        max-width: 100%;
    }
}

@media only screen and (max-width: 767px) {
    .timeline-item-content,
    .timeline-item:nth-child(odd) .timeline-item-content {
        padding: 15px 10px;
        text-align: center;
        align-items: center;
    }

    .timeline-item-content .tag {
        width: calc(100% - 10px);
        text-align: center;
    }

    .timeline-item-content time {
        margin-top: 20px;
    }

    .timeline-item-content a {
        text-decoration: underline;
    }

    .timeline-item-content a::after {
        display: none;
    }
}

Now, we have an <Timeline /> component we can use this in our functional or class components. For example we are using this in our App Component.

const App = () => <>
	<h1>React Timeline</h1>
	<Timeline />
</>;

ReactDOM.render(<App />, document.getElementById('app'));
