Control flow statements and loops are essential parts of any program, as they determine how code is executed. Control flow statements such as if statements and switch statements allow developers to execute code only if a certain condition is met. Loops allow developers to execute code multiple times until a certain condition is met, such as iterating through an array of items until all items have been accounted for.

CSS Explained: An Overview
CSS stands for Cascading Style Sheets. It is a styling language used for formatting elements on a webpage, such as font size, color, and spacing. CSS makes it easy to quickly apply styling across an entire website or application, making it possible for developers to create visually appealing websites with ease.
Syntax and Rules of CSS
CSS follows the syntax of HTML documents. The syntax consists of CSS selectors (classes, ids, tags) followed by declarations (specifying the styling). Declarations consist of property-value pairs that determine how the element should be styled.
Selectors, Properties, Values and Specificity in CSS
CSS selectors allow us to select HTML elements so we can apply styling only to specific elements on the page. Properties are used to specify what should be styled on the element (e.g., font size), while values determine how it should be styled (e.g., 18px). Specificity refers to how specific a selector is, with more specific selectors taking precedence over more general selectors.
CSS Box Model
The CSS Box Model is an important concept for web developers as it determines how elements will be sized and positioned on a webpage. Elements are composed of four boxes: margin, padding, border, and content box. Developers must understand how these boxes interact in order to design the layout of their webpage.
Positioning Elements with CSS
Positioning elements on a webpage can be controlled using CSS positioning properties such as absolute, relative and fixed positioning. Using these properties allows developers to create complex layouts that are responsive and look great on any device.
Media Queries for Responsive Design
Media queries allow developers to create responsive designs where the webpage responds based on the size of the device it is being viewed on. Media queries allow us to apply different styling based on the device type or resolution, making it easy to create designs that look great across any device.
