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.,<br>).
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; }, whereh2is the selector, andfont-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.
