Overview

  • Presenter: Ash Hamadani
  • Goals: Learn HTML and CSS from scratch, advanced concepts, and build a responsive, fast website.
  • Project: Develop a website for imaginary company Mashify.
  • Resources: Code editor (VS Code), browser (Google Chrome).

Tools and Setup

Code Editors

  • Recommendations: VS Code, Sublime Text, Atom.
  • VS Code Extensions:
    • Prettier: Code formatter (9+ million downloads).
    • Live Server: Launch websites in a development server (8+ million downloads).
  • Browser: Preferably Google Chrome for course consistency.

Fundamentals of Web Development

Key Concepts

  • Web Development: Front-end (HTML, CSS, JavaScript) and Back-end (databases, data management).
  • HTML: Structure of webpages.
  • CSS: Styling and beautifying webpages.
  • JavaScript: Adding functionality to webpages.
  • Analogy: HTML as the structure, CSS as aesthetics, JavaScript as functionality.

Development Roadmap

  1. HTML & CSS: Basic understanding in ~1 month.
  2. JavaScript: Basic understanding in ~6 weeks.
  3. Front-end Frameworks/Libraries:
    • Focus on React initially (~1-2 months for a comprehensive course).
  4. Version Control Systems: Git is the most popular (2 weeks to learn).

Key Web Concepts

  • URL: Uniform Resource Locator; identifies resources on the internet.
  • Client and Server: Client (browser) requests services from the server (web host).
  • HTTP/HTTPS: Protocol for client-server communication (HTTPS includes encryption).
  • DOM: Document Object Model; structure representing HTML elements.
  • Request-Response Cycle: Browser sends HTTP request, retrieves and renders HTML document from the server.

Inspecting Network Traffic

  • Chrome DevTools: Used to inspect network requests/responses.
  • Network Tab: View all HTTP requests and their details (status codes, timings, etc.).
  • Filtering Requests: By document type (document, font, etc.).

First HTML Document

Example

  • Create index.html with basic HTML structure: <!DOCTYPE html> <html> <head> <title>My First Web Page</title> </head> <body> <!-- Page content --> </body> </html>

Live Server

  • Use Live Server extension to view changes in real-time.

Applying CSS

Example

  • Embedding CSS in the head section: <style> img { width: 100px; } </style>
  • Use CSS to style HTML elements, e.g., float: left, border-radius: 50%.

Using DevTools

  • Inspect and modify DOM and CSS properties directly in the browser.
  • Ensure visual appeal and correct implementation.

Validation

HTML Validation

  • Tool: validator.w3.org
  • Fix typical issues such as lang attribute, missing alt in <img> tag.

CSS Validation

  • Tool: jigsaw.w3.org/css-validator

Text Formatting in HTML

Common Elements

  • Paragraph: <p> for text.
  • Emphasis: <em> for italic/emphasized text.
  • Strong: <strong> for bold text.
  • Avoid deprecated tags like <i> (italic) and <b> (bold).

Headings

  • Hierarchy: <h1> to <h6>.
  • Semantic use for headings, not just visual size.

Special Characters

  • Use HTML entities for reserved/special characters, e.g., &lt;, &gt;, &copy;.
  • Non-breaking space: &nbsp;.

Links and Navigation

  • Anchor Tag: <a href="...">Link Text</a>.
  • Internal Links: Relative URLs (e.g., about.html).
  • External Links: Absolute URLs with protocol (e.g., https://google.com).
  • Open in New Tab: target="_blank".
