Responsive web design allows websites to automatically adapt their layout to different screen sizes and devices using fluid grids, breakpoints, and media queries. Websites use relative units like percentages for layouts, breakpoints to specify CSS for different screen widths, and media queries to apply distinct styles based on screen size or device. Examples demonstrate how responsive design adapts content for different devices like mobile phones and desktops.

The document discusses various aspects of web page structure and styling including:
- Common HTML tags like <html>, <head>, <title>, <body> that provide the structure and metadata for a web page.
- CSS is used to style and lay out elements on the page through selectors like classes, IDs, and tags that target specific elements. Properties like font, color, size etc. are used to control styling.
- Additional CSS topics covered include links and hover effects, margins and spacing between elements, backgrounds, and headers/banners at the top of pages. External CSS style sheets are linked to pages to manage styles separately from the HTML.
This document discusses database tables and concepts such as:
- Tables contain rows and columns to organize data
- Primary keys uniquely identify each row in a table
- Foreign keys link data between tables by matching primary keys
- Common operations on tables include inserting, updating, deleting rows with SQL statements
- SQL statements like SELECT are used to query and retrieve data from one or multiple tables
1. PHP is a server-side scripting language that is commonly used for web development along with HTML and web servers like Apache.
2. PHP code is embedded within HTML code and interpreted by the web server before the page is sent to the browser.
3. Popular websites like Yahoo and Google were built using PHP because it allows developers to easily create dynamic and interactive web pages.
This document provides examples of using various PHP string handling and date functions. It demonstrates functions like substr(), str_replace(), strlen(), strpos(), strtolower(), strtoupper(), and date(). It also shows how to include external PHP files using the include statement to reuse code like custom functions across files.
This document discusses connecting a PHP application to a MySQL database. It shows how to connect to the database, execute SQL queries, and retrieve and display the results. Code examples are provided to connect to the database, run SELECT queries, fetch the results into arrays, and loop through the arrays to display the data. Functions are demonstrated to encapsulate the database connection and query execution code for reuse. Finally, examples show how to generate HTML tables and dropdown lists to display the database data.
