Study Notes

Module Objectives

Discuss fundamentals of HTML5, including document structure and elements.
Cover basics of CSS3, including syntax, application to HTML, selectors, properties, and colors.
Provide an overview of JavaScript fundamentals.

HTML Basics

HTML is essential for structuring web pages, organizing text, images, links, and other elements.
Standard HTML document structure includes <head> for metadata and links, and <body> for visible content.
Elements are defined by opening and closing tags, e.g., <div> for containers and  for paragraphs; some are self-closing like <img> for images.
Tags are enclosed in angle brackets; self-closing tags do not have a closing equivalent.
Attributes add information to elements, with common attributes including id, class, and href for links.

CSS Basics

CSS (Cascading Style Sheets) styles and layouts web pages, controlling appearance like colors, fonts, and spacing.
CSS can apply styles to multiple pages simultaneously, which enhances efficiency.
External stylesheets are stored in separate CSS files.

CSS Selectors, Properties, and Values

Selectors target HTML elements; includes type selectors (e.g., p), class selectors (e.g., .class), and ID selectors (e.g., #id).
Properties define styles, e.g., color: red; sets text color, font-size: 16px; adjusts text size.

Box Model and Layout Techniques

Box Model Concept

Content: Innermost area displaying the element's content, influenced by padding and border.
Padding: Space between content and element's border, adjustable with padding-top, padding-right, padding-bottom, and padding-left.
Border: Surrounds padding and content, customizable with border-width, border-style, and border-color.
Margin: Outermost space around an element, separates it from other elements, adjustable using margin-top, margin-right, margin-bottom, and margin-left.

Layout Techniques

Flexbox: A layout model for arranging items in a single axis (horizontal or vertical), simplifying responsive designs. Key properties include display: flex;, justify-content, align-items, and flex-direction.
Grid Layout: A two-dimensional layout system for complex designs using rows and columns. Defines control via display: grid;, with key properties like grid-template-rows, grid-template-columns, and grid-area.

JavaScript Basics

JavaScript enhances web pages with interactivity and dynamic features; operates on the client-side for user action responses and DOM manipulation.
Code consists of statements and expressions, with proper syntax crucial (e.g., semicolons, braces, parentheses).
Operators perform operations on variables, including arithmetic (+, -, *, /), comparison (==, ===, !=), and logical (&&, ||).
