HTML & CSS Architecture
Dive deep into the core building blocks of the web. This module focuses exclusively on writing clean, semantic structure, styling with modern rules, and constructing responsive UI from scratch without relying on frameworks.
Every great bridge requires a solid structure. In web development, HTML is the steel frame holding everything together. Let's look at how elements are nested.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>My Structural Document</title>
</head>
<body>
<main class="container">
<h1>Architecting The Web</h1>
<p>Paragraph elements encapsulate text blocks.</p>
<a href="#" class="btn">Click Action</a>
</main>
</body>
</html>
If HTML is the steel frame, CSS is the interior design, paint, and lighting. We target elements using selectors to build a cohesive visual aesthetic.
/* Global Reset */
* {
margin: 0;
padding: 0;
box-sizing: border-box;
/* Ensures padding doesn't inflate element width */
}
/* Targeting a Class */
.container {
max-width: 1200px;
margin: 0 auto; /* Centers the container */
background-color: #0a0a0f;
color: #ffffff;
}
Long gone are the days of floats and table layouts. Learn to leverage Flexbox for 1-dimensional layouts (navbars, cards) and CSS Grid for complex 2D architectures.
.hero-section {
display: flex;
justify-content: center; /* Center horizontally */
align-items: center; /* Center vertically */
min-height: 100vh; /* Full viewport height */
flex-direction: column; /* Stack items vertically */
gap: 1.5rem; /* Space between items */
}
Try It Yourself
Test your logic: How would you create a button that changes background color when the user hovers over it?
You use the :hover pseudo-class in CSS!
.btn {
background-color: #2563eb;
transition: background-color 0.3s ease;
}
.btn:hover {
background-color: #1d4ed8;
}
