Tab Bar Interaction

Tab Bar Interaction

Namaste!

Today we will understand about creating NavBar. We will use HTML, CSS, and Basic JavaScript.

Let’s go, just open your Code editor e.g. VSCode. Then Create a .html file and paste the below code into <body>HTML Code Here</body>

HTML Code:


<nav>
	<ul>
		<li>
			<a class="active">
				<svg><use xlink:href="#home-icon"></use></svg>
			</a>
		</li>
	</ul>
	<ul>
		<li>
			<a>
				<svg><use xlink:href="#bookmark-icon"></use></svg>
			</a>
		</li>
	</ul>
	<ul>
		<li>
			<a>
				<svg><use xlink:href="#plus-icon"></use></svg>
			</a>
		</li>
	</ul>
	<ul>
		<li>
			<a>
				<svg><use xlink:href="#user-icon"></use></svg>
			</a>
		</li>
	</ul>
	<ul>
		<li>
			<a>
				<svg><use xlink:href="#settings-icon"></use></svg>
			</a>
		</li>
	</ul>

	<div class="tubelight">
		<div class="light-ray"></div>
	</div>
</nav>

<div class="support">
	<a href="https://twitter.com/DevLoop01" target="_blank"><i class="fab fa-twitter-square"></i></a>
	<a href="https://dribbble.com/devloop01" target="_blank"><i class="fab fa-dribbble"></i></a>
</div>

Now, go for stying the tab bar. Create a .css file and Paste below code or paste it into <style>CSS CODE HERE</style> tag.

CSS Code:

:root {
  --background: #cecece;
  --scale: 1;
  --icon-size: 24px;
}

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  width: 100%;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  background: var(--background);
  overflow: hidden;
}

nav {
  position: relative;
  width: 350px;
  height: 80px;
  display: grid;
  grid-template-columns: repeat(5, 1fr);
  border-radius: 10px;
  padding: 0 15px;
  background: black;
  box-shadow: 0 6.7px 5.3px rgba(0, 0, 0, 0.12), 0 22.3px 17.9px rgba(0, 0, 0, 0.08), 0 100px 80px rgba(0, 0, 0, 0.04);
  overflow: hidden;
}
nav ul {
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}
nav ul li {
  list-style: none;
  width: var(--icon-size);
  height: var(--icon-size);
}
nav ul li a {
  display: block;
  width: 100%;
  height: 100%;
  cursor: pointer;
}
nav ul li a svg {
  fill: #fff;
  width: 100%;
  height: 100%;
  opacity: 0.4;
  transition: opacity 100ms ease;
  pointer-events: none;
}
nav ul li a.active svg {
  opacity: 1;
}
nav .tubelight {
  position: absolute;
  left: 0px;
  top: 0px;
  transform: translateX(-50%);
  width: 45px;
  height: 5px;
  border-radius: 5px;
  background: #ffffff;
  transition: left 400ms ease;
  z-index: 10;
}
nav .tubelight .light-ray {
  position: absolute;
  left: -30%;
  top: 5px;
  width: 160%;
  height: 80px;
  clip-path: polygon(5% 100%, 25% 0px, 75% 0px, 95% 100%);
  background: linear-gradient(to bottom, rgba(255, 255, 255, 0.3) -50%, rgba(255, 255, 255, 0) 90%);
  pointer-events: none;
}

.support {
  position: fixed;
  right: 10px;
  bottom: 10px;
  padding: 10px;
  display: flex;
}
.support a {
  margin: 0 10px;
  color: #222;
  font-size: 1.8rem;
  backface-visibility: hidden;
  transition: all 150ms ease;
}
.support a:hover {
  transform: scale(1.1);
}

For some backend work use a little javascript code. Paste below code.

JavaScript Code:

console.clear();

const uls = document.querySelectorAll("nav ul");
const links = [...document.querySelectorAll("nav a")];
const light = document.querySelector("nav .tubelight");

let activeIndex = 0;
let currentIndex = 0;
let increment = 1;
links.forEach((link, index) => {
	if (links[index].classList.contains("active")) {
		light.style.left = `${links[index].offsetLeft + light.offsetWidth / 4}px`;
	}

	link.addEventListener("click", e => {
		activeIndex = index;
		let t = setInterval(() => {
			if (activeIndex > currentIndex) increment = 1;
			else if (activeIndex < currentIndex) increment = -1;
			currentIndex += increment;

			links[currentIndex].classList.add("active");
			if (currentIndex != -1) links[currentIndex - increment].classList.remove("active");

			if (currentIndex == activeIndex) {
				e.target.classList.add("active");
				increment = 0;
				clearInterval(t);
			}
		}, 50);
		light.style.left = `${e.target.offsetLeft + light.offsetWidth / 4}px`;
	});
});

Thank You!
