HTML (HyperText Markup Language)

 Definition: background
HTML is the foundational language of the web. It is used to structure content on the internet. Every web page you see in a browser is built using HTML, either directly or through components that render HTML in thund.

 Purpose:
HTML provides the semantic structure of a webpage. It tells the browser what each part of a webpage is — such as headings, paragraphs, images, links, tables, forms, and more.

Key Concepts:
Tags and Elements: HTML is written in tags that define elements. Each tag tells the browser how to interpret the content it wraps.
Attributes: Tags often include attributes that add additional functionality or metadata.
Nesting: HTML supports nested elements, meaning elements can contain other elements.
Semantic HTML: HTML5 introduced semantic tags like,, andto give meaning to different sections of a page.

SCSS (Sassy CSS)

 Definition:
SCSS is a preprocessor scripting language that is interpreted or compiled into regular CSS. It adds powerful features to traditional CSS, making style management more organized, reusable, and efficient.
SCSS is designed to make writing CSS easier and more maintainable, especially for large or complex stylesheets.

Key Features:
Variables: Store values like colors, fonts, or spacing to be reused throughout stylesheets.
Nesting: Allows you to write CSS selectors in a hierarchical way that mimics the HTML structure.
Mixins: Create reusable groups of CSS declarations that can be included anywhere.
Partials and Imports: Split your SCSS into smaller, manageable files and import them as needed.
Operators and Functions: Perform calculations and logic inside your styles (e.g., for spacing or color adjustments).

Workflow:
SCSS files must be compiled into standard CSS using tools like the Sass CLI, build tools (Webpack, Gulp), or live compilers in text editors.

 Bootstrap

 Definition:
Bootstrap is a front-end framework developed to make building responsive and visually consistent websites faster and easier. It provides a complete toolkit of pre-written CSS and JavaScript components.

Purpose:
Bootstrap allows developers to quickly prototype and build professional-looking interfaces with minimal custom code. It promotes best practices for layout, typography, accessibility, and mobile-first design.

 Core Components:
Grid System: Based on flexbox, it allows for easy layout creation with responsive behavior across screen sizes.
Utility Classes: Ready-to-use classes for spacing, sizing, positioning, and alignment.
Responsive Breakpoints: Predefined screen size categories help apply styles for different devices.
UI Components: Pre-designed buttons, modals, navbars, cards, carousels, and more.
JavaScript Plugins: Built-in interactive behaviors like dropdowns, tooltips, and collapsible panels, which require no extra libraries.

Versions:
Bootstrap has evolved significantly:
Earlier versions used jQuery.
Version 5 and beyond have moved to pure JavaScript and CSS variables, making it more modern and lightweight.

How HTML, SCSS, and Bootstrap Work Together

When developing a website:

HTML defines the page structure. You use elements like headers, sections, and divs to organize content.
Bootstrap provides a set of CSS and JS tools to style that content and make it responsive by default. It is included in the project via CDN or NPM.
SCSS is used to extend or customize the Bootstrap styles, allowing for branding and fine-tuning without modifying the original Bootstrap files directly.
