Important aspects of CSS into case studies with sample code snippets for each

 

1. Selectors and Specificity

Case Study:

Creating a website with different sections styled uniquely based on their classes and IDs.

Sample Code:

/* Element Selector */
p {
font-size: 16px;
}
/* Class Selector */
.special-text {
color: red;
}

/* ID Selector */
#header {
background-color: #f1f1f1;
}

2. Box Model

Case Study:

Building a layout where elements have specific padding, margins, and borders.

Sample Code:

.box {
width: 200px;
height: 150px;
padding: 20px;
margin: 10px;
border: 1px solid #ccc;
}

3. Layout Techniques

Case Study:

Creating a flexible grid layout for a website with multiple content sections.

Sample Code (using CSS Grid):

.container {
display: grid;
grid-template-columns: 1fr 1fr; /* Two equal columns */
grid-gap: 20px; /* Gap between grid items */
}

4. Responsive Design

Case Study:

Adapting a webpage layout to different screen sizes using media queries.

Sample Code:

/* Responsive Design - Media Query */
@media screen and (max-width: 768px) {
.sidebar {
display: none; /* Hide sidebar on smaller screens */
}
}

5. Typography

Case Study:

Styling text elements for improved readability and aesthetics.

Sample Code:

body {
font-family: 'Arial', sans-serif;
line-height: 1.6;
text-align: justify;
}

6. CSS Preprocessors

Case Study:

Using Sass to manage styles more efficiently with variables and nesting.

Sample Code (Sass):

$primary-color: #3498db;

body {
background-color: $primary-color;
h1 {
color: darken($primary-color, 10%);
}
}

7. Transitions and Animations

Case Study:

Creating a smooth transition effect for a button on hover.

Sample Code:

/* Transition */
.button {
background-color: #3498db;
transition: background-color 0.3s ease;
}
.button:hover {
background-color: #2980b9;
}

8. CSS Frameworks

Case Study:

Using Bootstrap to quickly build a responsive navbar.

Sample Code (Bootstrap):

<nav class="navbar navbar-expand-lg navbar-light bg-light">
