Study Notes

Web Multimedia

Web multimedia involves HTML, CSS, and JavaScript.
Front-end: HTML (structure), CSS (decoration), and JavaScript (logic).
Back-end: server-side technologies (like PHP, Python, Ruby on Rails).

HTML: HyperText Markup Language for creating webpages/applications. It defines document structure, text content, and multimedia resources.
CSS: Cascading Style Sheets for presentation (how the content is displayed).
JavaScript: Multi-paradigm, open, cross-platform scripting language. Supports various programming styles (event-driven, functional, imperative) and is used for both client-side (user interaction) and server-side functions. It is fundamental to the web.

HTML DOM (Document Object Model)

When loading a web page, the browser creates a Document Object Model representing the page’s structure.
Types of nodes: elements and text.
Nodes (created in HTML or JavaScript) contain attributes, parameters, and JavaScript functions.

JavaScript Frameworks

Angular, Ember.js, Vue.js, Meteor, React Native, Backbone.js, Three.js, Aurelia

Web Functionality

Website (HTML, CSS, JavaScript) interacts with a server to display information.
Server stores data (and often application logic). CSS and JS help the browser render the page.

HTML5 Overview

HTML5 is the fifth major revision of the HTML standard. Published by W3C.
HTML5 supports many new elements and capabilities, including interaction, media, graphics, advanced styling effects, and a wide set of APIs.
Adaptable to various devices (desktop, mobile, tablet, TV).
Developed under open-source licenses.

What is Different About HTML5?

Simpler syntax, less complex documentation type.
Relaxed syntax constraints on tags and attributes.
Added new structural elements (like <nav>, <article>, <section>).

HTML5 Element Flowchart

Flowchart helps illustrate how to decide which HTML5 elements to use. Includes aspects like in-page navigation, content structure, and semantic elements.

Multimedia HTML5 Elements

HTML5 includes elements like <img>, <figure>, <figcaption>, <audio>, and <video>.

W3C Validators

Used for markup and CSS validation.
Provides tools to assess the correctness of HTML and CSS code.

Browser Compatibility & Debugging

Websites need to check support across different browsers.
Tools for debugging and testing code in browsers are essential.

Web Forms

Form controls (like text fields, radio buttons, etc.) are structured in HTML.
Controls using, <fieldset> and <legend> to group them properly.
Labels should be linked to their associated form controls using the for attribute.

HTML Attributes

accept: Used to specify the file types (formats) allowed in form input fields.
multiple: The allowed value in a form field can be more than one.
contenteditable: Allows HTML content to be edited on a webpage.

Useful HTML Attributes (2)

download: Allows the download of links.
translate: Specifies if the content should be translated when needed.

Client-side Validation

JavaScript validation for form elements can be coded for a lot of forms and functionalities.
HTML5 offers built-in validation features. This can handle basic form data needs like ensuring length or type. But JavaScript validation is more flexible

HTML Summary

Basic HTML concepts (goals, rules and structure) are required to build web pages.

HTML as a Tree

HTML is parsed into a tree-like structure (Document Object Model) by the browser.

DOM (Document Object Model)

The DOM is a representation of a webpage—a structured, tree-like model.
JavaScript can use the DOM to access and interact with web page elements.
