The World Wide Web (WWW) is a system of interconnected hypertext documents accessed through the internet. Uniform Resource Locators (URLs) are used to identify resources on the internet. HTML, XML, JSON, RSS, and JSONP are different data formats used for exchanging information over the internet. HTML is primarily used for web pages, while XML is more flexible and used for data exchange. JSON is commonly used for data transfer between a server and a web application, while RSS is a web feed format used to publish frequently updated content. JSONP is a method for cross-domain AJAX requests. The Hypertext Transfer Protocol (HTTP) is used to transfer data over the internet between web clients and servers. HTTP requests are used by clients to request resources from a server, while HTTP responses are used by servers to send requested resources back to clients. AJAX requests are asynchronous HTTP requests used to dynamically update web pages without requiring a full page refresh. The Same-Origin Policy is a security measure that prevents web pages from accessing resources on a different domain. Workarounds for the Same-Origin Policy include using JSONP or cross-origin resource sharing (CORS). Web Developer Tools are software applications used by developers to debug and optimize web applications.

CSS3 (Cascading Style Sheets) is a styling language used to describe the appearance and layout of a web page. CSS3 selectors are used to target specific HTML elements on a page and apply styles to them. CSS3 provides various font properties to control the appearance of text on a web page, including font-size, font-family, and font-weight. CSS3 also offers a wide range of color options, including the use of RGB and HSL values, as well as the ability to set transparency levels. Background properties such as background-color and background-image can be used to set the background of an element. CSS3 borders provide options for controlling the width, style, and color of borders around elements. The box model refers to the rectangular structure used to represent an element on a web page, including its content, padding, borders, and margins. CSS3 animations allow for the creation of smooth and interactive transitions between styles, bringing more dynamic visual effects to web pages.
