3 steps to create a responsive timeline component for Vue app

In this post you will learn about how to create a Timeline component with Vuejs in 3 steps.

Step 1: Create a Timeline component with script codes bellow:

const timelineData = [
  {
    datetime: "2019",
    event: "Something happened in 2019"
  },
  {
    datetime: "2018",
    event: "Something happened in 2018"
  },
  {
    datetime: "2017",
    event: "Something happened in 2017"
  },
  {
    datetime: "2016",
    event: "Something happened in 2016"
  },
  {
    datetime: "2015",
    event: "Something happened in 2015"
  }
];
export default {
  data(){
    return {
      events: timelineData
    }
  }
};

In script codes we defined a timelineData array contains all events that you want to show in timeline.

Step 2: binding your events in Vue template:

Step 3: put a bit of css codes bellow to your app

 body {
  background-color: #6e97ea;
}
* {
  box-sizing: border-box;
}

.timeline {
  position: relative;
  max-width: 1200px;
  margin: 0 auto;
}

.timeline::after {
  content: "";
  position: absolute;
  width: 3px;
  background-color: white;
  top: 0;
  bottom: 0;
  left: 50%;
  margin-left: -2px;
}

.timeline-item {
  padding: 10px 40px;
  position: relative;
  background-color: inherit;
  width: 50%;
}

.timeline-item::after {
  content: "";
  position: absolute;
  width: 15px;
  height: 15px;
  right: -9px;
  background-color: #4caf50;
  border: 2px solid #fff;
  top: 22px;
  border-radius: 50%;
  z-index: 1;
}

.left {
  left: 0;
}

.right {
  left: 50%;
}

.left::before {
  content: " ";
  height: 0;
  position: absolute;
  top: 22px;
  width: 0;
  z-index: 1;
  right: 30px;
  border: medium solid white;
  border-width: 10px 0 10px 10px;
  border-color: transparent transparent transparent white;
}

.right::before {

  z-index: 1;
  left: 30px;
  border: medium solid white;
  border-width: 10px 10px 10px 0;
  border-color: transparent white transparent transparent;
}

.right::after {
  left: -10px;
}

.content {
  padding: 20px 30px;
  background-color: white;
  position: relative;
  border-radius: 6px;
}

/* Responsive on screens less than 600px wide */
@media screen and (max-width: 600px) {
  .timeline::after {
    left: 31px;
  }

  .timeline-item {
    width: 100%;
    padding-left: 70px;
    padding-right: 25px;
  }

  .timeline-item::before {
    left: 60px;
    border: medium solid white;
    border-width: 10px 10px 10px 0;
    border-color: transparent white transparent transparent;
  }

  .left::after,
  .right::after {
    left: 21px;
  }

  .right {
    left: 0%;
  }
