Study Notes

HTML

HyperText Markup Language, a fundamental technology for creating web pages.
Comprises a series of markup tags that describe different types of content within a document.
Tags typically come in pairs: a start tag (e.g., <tag>) and an end tag (e.g., </tag>), with some being empty tags (e.g.,  ).

Tag Examples

Start and end tags are used to define elements, indicating where elements begin and end.
An example of a simple HTML structure includes a start tag, content, and an end tag.

JavaScript

An extension of HTML that allows for client-side interactivity.
An object-based scripting language that operates in an event-driven manner.
Enables input processing and output to enhance user interaction with web pages.

CSS

Cascading Style Sheets control the visual presentation of web pages, including layouts, fonts, and background colors.
CSS rules consist of selectors and declarations, e.g., h2 { font-style: italic; }, where h2 is the selector, and font-style: italic; is the declaration.

PHP

PHP (Hypertext Preprocessor) allows the integration of HTML, JavaScript, CSS, and server-side scripting.
Documents generally consist of a combination of these technologies, with HTML, JavaScript, and CSS rendered on the client-side.
PHP code is executed on the server, rendering the output (often HTML, JavaScript, or CSS) that is sent to the client.

PHP Structure

HTML, JavaScript, CSS, and embedded PHP code work together in a PHP document.
PHP scripts are typically embedded within a PHP tag (<?php ... ?>) for processing on the server before being delivered to the browser.
