Hello everyone! In this tutorial lets build a responsive navbar and hamburger menu using html,css and a little bit of javascript.

This is how it will look,

So let's start with the HTML,


 HTML
<header class="header">
        <nav class="navbar">
            <a href="#" class="nav-logo">WebDev.</a>
            <ul class="nav-menu">
                <li class="nav-item">
                    <a href="#" class="nav-link">Services</a>
                </li>
                <li class="nav-item">
                    <a href="#" class="nav-link">Blog</a>
                </li>
                <li class="nav-item">
                    <a href="#" class="nav-link">About</a>
                </li>
                <li class="nav-item">
                    <a href="#" class="nav-link">Contact</a>
                </li>
            </ul>
            <div class="hamburger">
                <span class="bar"></span>
                <span class="bar"></span>
                <span class="bar"></span>
            </div>
        </nav>
</header>

Here, we have

header with the class of header which work as a container of our navbar
nav with the class of navbar
a link with the class of nav-logo
ul with the class of nav-menu
inside the ul we have 4 lis with the class of nav-item
inside each nav-item we have a link with the class of nav-link
for our hamburger I have added a div with the class of hamburger and inside which we have 3 spans with the class of bar

So this is the HTML that we need.

Now let's add the CSS reset

(Here we will import the font we need and add some basic CSS to reset all the default styles.


 CSS
@import url('https://fonts.googleapis.com/css2?family=Roboto:ital,wght@0,500;1,400&display=swap');

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

html {
    font-size: 62.5%;
    font-family: 'Roboto', sans-serif;
}

li {
    list-style: none;
}

a {
    text-decoration: none;
}

Now let's add styles to the elements one by one,

header and navbar


 CSS
.header{
    border-bottom: 1px solid #E2E8F0;
}

.navbar {
    display: flex;
    justify-content: space-between;
    align-items: center;
    padding: 1rem 1.5rem;
}

hamburger styles


 CSS
.hamburger {
    display: none;
}

.bar {
    display: block;
    width: 25px;
    height: 3px;
    margin: 5px auto;
    -webkit-transition: all 0.3s ease-in-out;
    transition: all 0.3s ease-in-out;
    background-color: #101010;
}

basic styles for our other elements ``` CSS .nav-menu { display: flex; justify-content: space-between; align-items: center; }

.nav-item {
margin-left: 5rem;
}

.nav-link{
font-size: 1.6rem;
font-weight: 400;
color: #475569;
}

.nav-link:hover{
color: #482ff7;
}

.nav-logo {
font-size: 2.1rem;
font-weight: 500;
color: #482ff7;
}

### After this, It should look like this,

# But It's not responsive yet, so let's add the media queries.

CSS
@media only screen and (max-width: 768px) {
.nav-menu {
position: fixed;
left: -100%;
top: 5rem;
flex-direction: column;
background-color: #fff;
width: 100%;
border-radius: 10px;
text-align: center;
transition: 0.3s;
box-shadow:
0 10px 27px rgba(0, 0, 0, 0.05);
}

.nav-menu.active {
    left: 0;
}

.nav-item {
    margin: 2.5rem 0;
}

.hamburger {
    display: block;
    cursor: pointer;
}

}

What this media query does is, hides our `nav-menu` by setting `position: fixed;`  `left: -100%;` on it.
Also, we set our `hamburger` to `display: block;` so it's visible now. 
We have also added an extra class that is `.nav-menu.active` which sets `left: 0;` on the `nav-menu`. Now we will have to add the javascript which will add this `active` class on the nav-menu when we click our hamburger.

# Let's add the javascript.

Javascript
const hamburger = document.querySelector(".hamburger");
const navMenu = document.querySelector(".nav-menu");

hamburger.addEventListener("click", mobileMenu);

function mobileMenu() {
hamburger.classList.toggle("active");
navMenu.classList.toggle("active");
}


Here the function `mobileMenu()` also adds an `active` class on our `hamburger` and our `nav-menu` which makes our mobile menu open.  we can use the active class on the hamburger to create that X animation when we click on the `hamburger`. so let's do that now.

CSS
// Inside the Media Query.

.hamburger.active .bar:nth-child(2) {
    opacity: 0;
}

.hamburger.active .bar:nth-child(1) {
    transform: translateY(8px) rotate(45deg);
}

.hamburger.active .bar:nth-child(3) {
    transform: translateY(-8px) rotate(-45deg);
}

### It should look like this now,

## But there is a catch, the hamburger menu doesn't close when we click a link. So let's add that now,

Javascript
const navLink = document.querySelectorAll(".nav-link");

navLink.forEach(n => n.addEventListener("click", closeMenu));

function closeMenu() {
hamburger.classList.remove("active");
navMenu.classList.remove("active");
}


The `closeMenu()` function removes the `active` class from both the `nav-menu` and the `hamburger` which makes our mobile menu close.
