Hello guys, in this post I am going to share with you the source code of a Horizontal Navigation bar with drop-down and dark mode. It will look like Google support's(site) navigation bar. In this post, I am deeply explaining each CSS code and its purpose in this project and how it gives an awesome look.
The header contains a navigation bar icon and site name on the left side and the search icon on the right side. If the user clicks on the top left navigation icon the Navigation bar will be visible in a vertical look. Both the search box and navigation come with a smooth animation. This navigation bar is almost similar to this site's navigation bar (fluratech 2022 template).
Also, this is a simple and Responsive design.
This video will give you an idea about the navigation bar.
For this project, you want to create 3 files(index.html, style.css and script.js) in a folder.
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

CSS variables
Here I have made two variable lists one for light mode and another for dark mode.
:root {
--headerColor: rgb(0, 60, 255);
--FontColor: rgb(56, 56, 56);
--bodyColor: rgb(207, 207, 207);
--colorday: rgb(255, 255, 255);
--colorchan: rgb(255, 255, 255);
}
/* night mode */
body.dark {
--headerColor: rgb(0, 60, 255);
--FontColor: rgb(212, 212, 212);
--bodyColor: rgb(23, 23, 31);
--colorday: rgb(255, 255, 255);
--colorchan: rgb(66, 58, 58);
}
Basic template design
Here I have added all the basic code to make the display the same output seen in the video.
* {
margin: 0%;
padding: 0%;
box-sizing: border-box;
text-decoration: none;
}
body {
background-color: var(--bodyColor);
}
main{
height:90vh;
display: flex;
justify-content: center;
align-items: center;
font-size: 30px;
font-weight: 800;
text-align: center;
color: var(--FontColor);
}
Header
Here I have only added the code for the look, alignment and javascript function access. The header contains a navigation bar icon and site name on the left side and the search icon on the right side. If the user clicks on the top left navigation icon the Navigation bar will be visible in a vertical look. Both the search box and navigation come with a smooth animation.
header {
background-color: var(--headerColor);
color: var(--colorday);
}
header .headerContainer {
max-width: 1200px;
margin: auto;
display: flex;
justify-content: space-between;
padding: 20px 0 20px 0;
}
header .headerContainer .leftContent h1 {
font-size: 30px;
display: inline-block;
margin-left: 20px;
color: var(--colorday);
transition: 0.7s;
}
header .headerContainer .leftContent span {
font-size: 25px;
margin-left: 20px;
cursor: pointer;
padding: 10px;
transition: 0.7s;
}
header .headerContainer .rightContent span {
font-size: 25px;
margin-right: 20px;
cursor: pointer;
padding: 10px;
}
header .headerContainer span:hover {
background-color: rgb(67, 67, 117);
border-radius: 50%;
}
Navigation-bar
This code will give a look and alignment for both the navigation and dropdown. The navigation bar is fixed on the left side and its position will not change.
/* Navigation */
nav {
width: 300px;
position: fixed;
top: 0;
left: -400px;
background-color: var(--colorchan);
height: 100vh;
font-size: 20px;
transition: .3s;
overflow: auto;
}
nav .navname {
display: block;
display: flex;
justify-content: space-between;
border-bottom: 1px solid var(--FontColor);
color: var(--FontColor);
}
nav .navname b {
font-size: 30px;
font-weight: 700;
color: var(--headerColor);
padding: 20px 10px 20px 10px;
}
nav ul {
padding-left: 20px;
list-style: none;
color: var(--FontColor);
}
nav ul li {
font-weight: 600;
margin: 10px 0 10px 0;
border-radius: 10px 0 0 10px;
}
nav ul a {
color: var(--FontColor);
display: block;
}
nav ul li a:hover {
color: var(--headerColor);
}
nav ul ul {
display: none;
}
nav ul ul li {
font-weight: 550;
font-size: 18px;
padding: 0px;
}
.dropIcon {
float: right;
margin-right: 5px;
}
.dropdown {
cursor: pointer;
}
Media query
The browser equal to or smaller than 400 px will affect the look of the site. So I have added media query to maintain its size to 100%.
@media only screen and (max-width:400px) {
nav{width: 100%;}
}
All CSS code in one
This is all the CSS code that we discussed previously.
* {
margin: 0%;
padding: 0%;
box-sizing: border-box;
text-decoration: none;

background-color: var(--bodyColor);

--colorday: rgb(255, 255, 255);
--colorchan: rgb(255, 255, 255);
}
header {
background-color: var(--headerColor);
color: var(--colorday);
}
header .headerContainer {
max-width: 1200px;
margin: auto;
display: flex;
justify-content: space-between;
