Chapter 2: HTML Essentials

HTML is a crucial element of web development. Let's delve into the recent advancements brought by HTML5:

1. New Features in HTML5:

   • Tags: Introduction of semantic tags (like <aside>, <figure>, <section>, <header>, <footer>, and <nav>), along with multimedia tags for video and audio, to improve the separation of style and structure.
   • Attributes: Enhancements to the form, focusing on the type attribute, and additions like charset in <meta> for character set specification, as well as async in <script> for asynchronous loading.
   • Storage: New options for storage, including localStorage, sessionStorage, and indexedDB, plus application cache to save web applications.
   • APIs: Introduction of various APIs, including drag-and-drop, geolocation, SVG and canvas drawing, Web Workers, and WebSockets.

2. Understanding Doctype:

   The doctype declaration informs the browser about the document standard it should use, which can affect how the page renders:

   • Quirks Mode: Activated when no doctype is present, leading to inconsistent rendering.
   • Standards Mode: Follows W3C standards for document parsing.

3. Front-End Storage Types:

   • Cookies: The traditional method for local storage, limited to 4KB, automatically sent with HTTP requests, and generally well-supported.
   • LocalStorage: A new HTML5 feature that offers persistent storage with a capacity of 5MB, retaining data even after the page is closed.
   • SessionStorage: Similar to LocalStorage but clears data when a tab is closed, with no data sharing between tabs.
   • IndexedDB: A NoSQL database option for asynchronous operations, capable of storing over 250MB of data, but subject to the same-origin policy.
   • Web SQL: A relational database option that allows SQL operations within the browser, but comes with compatibility concerns.

4. href vs. src Attributes:

   • href (Hyper Reference): Allows the browser to download resources in parallel, enhancing page performance (e.g., using <link> for CSS).
   • src (Source): Causes the browser to pause rendering until the resource is fully downloaded, which is why <script> tags are typically placed at the end of the document.

5. Meta Tag Attributes:

   The <meta> tag provides essential metadata for web pages:

   • charset: Defines the character encoding of the document.
   • http-equiv: Mimics HTTP headers for cache control and expiration.
   • viewport: Controls the layout on mobile browsers.

6. Viewport Parameters:

   The viewport meta tag has several parameters:

   • width/height: Specifies the viewport dimensions.
   • initial-scale: Sets the initial zoom level.
   • maximum-scale/minimum-scale: Limits user zoom capabilities.
   • user-scalable: Determines whether users can zoom in or out.

7. Functions of the http-equiv Attribute:

   • expires: Sets expiration for the content.
   • pragma: Disables caching.
   • refresh: Regularly refreshes the page.
   • set-cookie: Manages cookies.
   • X-UA-Compatible: Specifies the browser version to use.
