Here is the HTML:

                    <div class="year">2008 <span class="marker"><span class="dot"></span></span>
                    </div>
                    <div class="info">That song the artist formerly known as prince sang no longer applies.</div>
                </div>
                <div class="timeline-item">
                    <div class="year">2008 <span class="marker"><span class="dot"></span></span>
                    </div>
                    <div class="info">The in-house Gawker chat room is filled with photos of Rob Ford, and for one reason: Rob Ford takes a good goddamn photo.</div>

Here's the CSS:

            div {
                font-family: Helvetica, Arial, sans-serif;
                box-sizing: border-box;
            }
            .timeline {
                width: 400px;
            }
            .timeline .timeline-item {
                width: 100%;
            }
            .timeline .timeline-item .info, .timeline .timeline-item .year {
                color: #eee;
                display: block;
                float:left;
                -webkit-transition: all 1s ease;
                -moz-transition: all 1s ease;
                transition: all 1s ease;
            }
            .timeline .timeline-item.close .info, .timeline .timeline-item.close .year {
                color: #ccc;
                -webkit-transition: all 1s ease;
                -moz-transition: all 1s ease;
                transition: all 1s ease;
            }
            .timeline .timeline-item .year {
                font-size: 24px;
                font-weight: bold;
                width: 22%;
            }
            .timeline .timeline-item .info {
                width: 100%;
                width: 78%;
                margin-left: -2px;
                padding: 0 0 40px 35px;
                border-left: 4px solid #aaa;
                font-size: 14px;
                line-height: 20px;
            }
            .timeline .timeline-item .marker {
                background-color: #fff;
                border: 4px solid #aaa;
                height: 20px;
                width: 20px;
                border-radius: 100px;
                display: block;
                float: right;
                margin-right: -14px;
                z-index: 2000;
                position: relative;
            }
            .timeline .timeline-item.active .info, .timeline .timeline-item:hover .info {
                color: #444;
                -webkit-transition: all 1s ease;
                -moz-transition: all 1s ease;
                transition: all 1s ease;
            }
            .timeline .timeline-item.active .year, .timeline .timeline-item:hover .year {
                color: #9DB668;
            }
            .timeline .timeline-item .marker .dot {
                background-color: white;
                -webkit-transition: all 1s ease;
                -moz-transition: all 1s ease;
                transition: all 1s ease;
                display: block;
                border: 4px solid white;
                height: 12px;
                width: 12px;
                border-radius: 100px;
                float: right;
                z-index: 2000;
                position: relative;
            }
            .timeline .timeline-item.active .marker .dot, .timeline .timeline-item:hover .marker .dot {
                -webkit-transition: all 1s ease;
                -moz-transition: all 1s ease;
                transition: all 1s ease;
                background-color: #9DB668;
                box-shadow: inset 1px 1px 2px rgba(0, 0, 0, 0.2);
            }

      

        
        
        
      

    

Here is JQuery:

            $(".timeline-item").hover(function () {
                $(".timeline-item").removeClass("active");
                $(this).toggleClass("active");
                $(this).prev(".timeline-item").toggleClass("close");
                $(this).next(".timeline-item").toggleClass("close");
            });
