Study Notes

CSS Overview

CSS stands for Cascading Style Sheets, crucial for styling HTML elements.
CSS files are typically text files with a .css extension, containing rules for presentation.
HTML provides structure, while CSS focuses on styling, enhancing web aesthetics.

Benefits of CSS

Separates content structure from presentation for cleaner code.
Offers advanced control over layout and design.
Simplifies maintenance across multiple web pages, saving time.
Improves page loading speeds due to reduced code size.
Enhances accessibility features for users with disabilities.
Designed for ease of use, making it beginner-friendly.

Page Structure and Organization

Without CSS, HTML elements default to a linear, top-to-bottom flow and left alignment.
CSS allows the creation of containers (DIVs) for better organization and visual appeal.
A typical web page structure includes elements such as header, navigation, content, and footer.

Box Model Concept

CSS operates on the box model, where each element is represented as a rectangular box.
Boxes can be stacked, nested, and floated for dynamic layouts.

Attaching CSS Styles

Stylesheets can be incorporated into an HTML page through three methods:
- External Style Sheet: Ideal for uniform styling across multiple pages.
- Internal Style Sheet: Useful for single-page styling controls.
- Inline Style Sheet: Applies CSS directly within HTML tags (less common).

CSS Rule Structure

A CSS rule consists of a selector and a declaration.
Declarations are composed of properties and their corresponding values.
Grouping selectors can consolidate multiple selectors with identical declarations for efficiency.

Additional CSS Features

Comments can be added for code clarity, serving as helpful notes for self or others.
Comments begin with /* and end with */.

DIV Elements in Web Development

A standard HTML web page is structured using containers (DIVs).
Each DIV can be identified with an ID or class, facilitating targeted styling.
