Vertical Progress Indicator using JavaScript

Hello Coders! Welcome to another JavaScript Blog. In this, we're going to see how to create a responsive Vertical Progress Indicator using Javascript. You might have seen animation like this in many websites where you have to complete a course or the steps that you have completed. This is a better user-friendly approach to show users how much they completed and how much are yet to be finished.

Here's a preview -

That being said, let us get started.

Step - 1: Like always, create 3 files - index.html, style.css and script.js.

Step - 2: Copy the below HTML code and paste it into your code editor.

HTML


<!DOCTYPE html>
<html lang="en" >
<head>
  <meta charset="UTF-8">
  <title>Responsive Vertical Progress Indicator</title>
  <link rel="stylesheet" href="./style.css">

</head>
<body>
<div class="outer">
  <div class="progress">
    <div class="left">
      <div>Start</div>
      <div></div>
      <div></div>
      <div class="current"></div>
      <div>Framework</div>
      <div></div>
      <div></div>
    </div>
    <div class="right">
      <div>Intro</div>
      <div>HTML</div>
      <div>CSS</div>
      <div class="current">Javascript</div>
      <div>React</div>
      <div>Node</div>
      <div class="done">Done</div>
    </div>
  </div>
</div>

  <script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js'></script><script  src="./script.js"></script>

</body>
</html>

Step - 3: Below is the CSS code for styling.

CSS


@import url("https://fonts.googleapis.com/css?family=Lato");
body {
  margin: 0;
  padding: 0;
  font-family: "Lato", Arial, sans-serif;
  display: flex;
}
.outer {
  height: 90vh;
  min-width: 20vw;
  flex: 1;
}
.progress {
  display: inline-flex;
  height: 100%;
  padding: 5vh 10%;
}
.progress > div {
  display: flex;
  flex-direction: column;
  color: #333;
}
.progress > div.left {
  padding-right: 20px;
  text-align: right;
}
.progress > div.left div:last-of-type:after {
  display: none;
}
.progress > div.left div:after {
  content: "";
  background: rgba(51, 51, 51, 0.1);
  border-radius: 2px;
  position: absolute;
  right: -20px;
  top: 10px;
  height: 101%;
  width: 1px;
  transform: translateX(50%);
}
.progress > div.right {
  padding-left: 20px;
}
.progress > div.right div.prev:after {
  transition: none;
}
.progress > div.right div.current {
  color: #333;
  font-weight: bold;
}
.progress > div.right div.current:before {
  background: #333;
  padding: 10px;
  transition: all 0.2s 0.15s cubic-bezier(0.175, 0.885, 0.32, 2);
}
.progress > div.right div.current:after {
  height: 0%;
  transition: height 0.2s ease-out;
}
.progress > div.right div.current ~ div {
  color: #666;
}
.progress > div.right div.current ~ div:before {
  background: #666;
  padding: 2.5px;
}
.progress > div.right div.current ~ div:after {
  height: 0%;
  transition: none;
}
.progress > div.right div:before {
  content: "";
  background: #333;
  padding: 5px;
  border-radius: 50%;
  position: absolute;
  left: -20px;
  top: 10px;
  transform: translateX(-50%) translateY(-50%);
  transition: padding 0.2s ease;
}
.progress > div.right div:after {
  content: "";
  background: #333;
  border-radius: 2px;
  position: absolute;
  left: -20px;
  top: 10px;
  height: 101%;
  width: 2px;
  transform: translateX(-50%);
  transition: height 0.2s ease;
}
.progress > div div {
  flex: 1;
  position: relative;
  line-height: 20px;
  cursor: default;
  min-height: 30px;
}
.progress > div div:last-of-type {
  flex: 0;
}

.done.current {
  color: #62af0b !important;
}
.done.current:before {
  background: #62af0b !important;
}

Step - 4: Below is the JavaScript code which is the most important part in this animation.

JS


"use strict";
$('.progress').each((_, progress) => {
    const steps = $('> div.right > div', progress);
    steps.each((i, el) => $(el).mouseenter(e => onHover(el)));
    const onHover = (el) => {
        steps.removeClass(['current', 'prev']);
        el.classList.add('current');
        $(el).prevAll().slice(1).addClass('prev');
    };
});

And that's it. You're done.
