Here's My Css code
```css
@import url("https://fonts.googleapis.com/css?family=Muli&display=swap");

:root {
  --line-border-fill: #3498db;
  --line-border-empty: #e0e0e0;
}

* {
  box-sizing: border-box;
}

body {
  background-color: #f6f7fb;
  font-family: "Muli", sans-serif;
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
  overflow: hidden;
  margin: 0;
}

.container {
  align-items: center;
}

.progress-container {
  display: flex;
  justify-content: space-between;
  position: relative;
  margin-bottom: 30px;
  max-width: 100%;
  width: 350px;
}

.progress-container::before {
  content: "";
  background-color: var(--line-border-empty);
  position: absolute;
  top: 50%;
  left: 0%;
  transition: translateY(-50%);
  height: 4px;
  width: 100%;
  z-index: -1;
}

.progress {
  background-color: var(--line-border-fill);
  position: absolute;
  top: 50%;

  transition: 0.4s ease;
}

.circle {

}

.circle.active {
  border-color: var(--line-border-fill);
}

.btn {
  background-color: var(--line-border-fill);
  color: #fff;
  border: 0;
  border-radius: 6px;
  cursor: pointer;
  font-family: inherit;
  padding: 8px 30px;
  margin: 5px;
  font-size: 14px;
}

.btn:active {
  transform: scale(0.98);
}

.btn:focus {
  outline: 0;
}

.btn:disabled {
  background-color: var(--line-border-empty);
  cursor: not-allowed;
}
```
Here's My JAVASCRIPT code
```javascript
const progress = document.getElementById("progress");
const prev = document.getElementById("prev");
const next = document.getElementById("next");
const circles = document.querySelectorAll(".circle");

let currentActive = 1;

next.addEventListener("click", () => {
  currentActive++;

  if (currentActive > circles.length) {
    currentactive = circles.length;
  }

  update();
});
prev.addEventListener("click", () => {
  currentActive--;

  if (currentActive < 1) {
    currentactive = 1;
  }

  update();
});

function update() {
  circles.forEach((circle, idx) => {
    if (idx < currentActive) {
      circle.classList.add("active");
    } else {
      circle.classList.remove("active");
    }
  });

  const actives = document.querySelectorAll(".active");

  progress.style.width =
    ((actives.length - 1) / (circles.length - 1)) * 100 + "%";

  if (currentActive === 1) {
    prev.disabled = true;
  } else if (currentActive === circles.length) {
    next.disabled = true;
  } else {
    prev.disabled = false;
    next.disabled = false;
  }
}
```
