<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Modern Website Layout</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<header>
<h1>My Website</h1>
</header>
<nav>
<a href="#">Home</a>
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Contact</a>
</nav>
<section class="hero">
<h2>Welcome to Modern Web Design</h2>
<p>Create beautiful websites with HTML and CSS.</p>
</section>
<main>
<section class="content">
<h2>Latest Articles</h2>
<p>Your content goes here...</p>
</section>
<aside class="sidebar">
<h3>Quick Links</h3>
</aside>
</main>
<footer>

</footer>
</body>
</html>
Styling the Layout
*{
margin:0;
padding:0;
box-sizing:border-box;
}
body{
font-family:Arial, sans-serif;
line-height:1.6;
background:#f5f5f5;
}
header{
background:#1E3A8A;
color:white;
text-align:center;
padding:30px;
}
nav{
display:flex;
justify-content:center;
gap:20px;
background:#2563EB;
padding:15px;
}
nav a{
color:white;
text-decoration:none;
font-weight:bold;
}
.hero{
text-align:center;
padding:80px 20px;
background:#DBEAFE;
}
main{
display:grid;
grid-template-columns:3fr 1fr;
gap:20px;
padding:30px;
}
.content,
.sidebar{
background:white;
padding:20px;
border-radius:10px;
}
footer{
text-align:center;
padding:20px;
background:#1E3A8A;
color:white;
}
Making the Layout Responsive
Use a media query to adapt the layout for smaller screens.
@media (max-width:768px){
main{
grid-template-columns:1fr;
}
nav{
flex-direction:column;
align-items:center;
}
}
Now the sidebar moves below the main content, and the navigation links stack vertically on mobile devices.
Building a Hero Section
The hero section is the first thing visitors see.
Example:
.hero{
padding:100px 20px;
background:linear-gradient(
135deg,
#2563EB,
#1E40AF
);
color:white;
}
Add a call-to-action button:
<a href="#" class="btn">
Get Started
</a>
.btn{
display:inline-block;
margin-top:20px;
padding:12px 30px;
background:white;
color:#2563EB;
text-decoration:none;
border-radius:6px;
transition:.3s;
}
.btn:hover{
background:#E5E7EB;
}
Creating a Card Section
Cards are widely used for services, products, and blog posts.
.cards{
display:grid;
grid-template-columns:
repeat(auto-fit,minmax(250px,1fr));
gap:20px;
}
.card{
background:white;
padding:25px;
border-radius:10px;
box-shadow:0 4px 10px rgba(0,0,0,.1);
}
Cards automatically rearrange themselves based on screen width.
Adding Hover Effects
Interactive elements improve user experience.
.card{
transition:transform .3s;
}
.card:hover{
transform:translateY(-8px);
}

<header>,<main>,<section>, and<footer>.Build layouts with CSS Grid and Flexbox instead of floats.
