CSS Roadmap Summary

The CSS Roadmap provides a structured approach for beginners to learn CSS (Cascading Style Sheets), which is essential for styling web pages. This guide outlines the key concepts and a learning path for mastering CSS.

What is CSS?

• Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in HTML or XML.
• CSS controls the layout, colors, fonts, and overall visual aesthetics of web pages.

Key Concepts in CSS

1. Selectors

• Definition: Selectors are patterns used to select the elements you want to style.
• Types of Selectors:
  • Element Selector: Selects elements by their tag name (e.g., p for paragraphs).
  • Class Selector: Selects elements with a specific class (e.g., .classname).
  • ID Selector: Selects a unique element with a specific ID (e.g., #idname).

2. Properties and Values

• Definition: Properties are the style attributes you want to change (e.g., color, font-size), and values are what you assign to those properties.

Example:

p {
    color: blue; /* Property: color, Value: blue */
    font-size: 16px; /* Property: font-size, Value: 16px */
}

3. Box Model

• Definition: The box model describes the rectangular boxes generated for elements in the document tree and consists of margins, borders, padding, and the actual content.
• Components:
  • Content: The actual content of the box (text, images).
  • Padding: Space between the content and the border.
  • Border: The line surrounding the padding.
  • Margin: Space outside the border.

4. Flexbox and Grid

• Flexbox: A layout model that allows responsive design by distributing space along a single axis.
• Grid: A two-dimensional layout system that enables complex designs using rows and columns.

5. Responsive Design

• Definition: Creating web pages that look good on all devices by using flexible layouts, images, and CSS media queries.

Example:

@media (max-width: 600px) {
    body {
        background-color: lightblue; /* Changes background on smaller screens */
    }
}
