By default, when you set a width or height on an element, it only applies to the content area. The padding, border, and margin are added on top of this width or height. For example, if you set the following CSS on a <p> element: p { width: 100px; padding: 10px; border: 10px solid black; margin: 10px; } The browser will render it like this: However, you can change this behavior by using the box-sizing property....
CSS Inheritance is a concept where properties set on a selector are inherited by its children. While not all properties exhibit this behavior, it helps in writing concise and efficient CSS code by avoiding the need to set the same property for each individual child element. Certain properties, such as font-related properties, are logical to be inherited, as they can be applied to the parent element and automatically flow down to its children....
In web development, CSS specificity plays a crucial role when multiple rules target the same element with different selectors affecting the same property. So, how do you determine which rule takes precedence over the others? The answer lies in the concept of specificity. Let’s consider an example to understand this better: <p class="dog-name">Roger</p> We have two rules that target this <p> element: .dog-name { color: yellow; } p { color: red; } In addition, we have another rule that targets p....
In the world of electronics, different terms are often used to refer to the same concept. It’s important to grasp these terms to build a solid foundation in electronics. One commonly mentioned concept is the negative pole of the battery, which can be referred to as “-”, “0V”, the ground, “GND”, or “Vss”. These terms all indicate the same thing - the negative pole of the battery that is at 0V....
In JavaScript, event propagation can occur in two models: event bubbling and event capturing. Let’s explore how these models work and how they can be applied to your code. Let’s say you have the following DOM structure: <div id="container"> <button>Click me</button> </div> You want to track when users click on the button, and you have two event listeners - one on the button itself and one on the #container element....
If you’re into serverless computing with AWS Lambda, you’ve likely come across the term “GB-seconds.” But what exactly does it mean? And how does it affect your usage on the platform? In simple terms, GB-seconds refer to the measurement of your function’s runtime in relation to the amount of memory it consumes. To put it into context, AWS Lambda provides users with 1 million free requests per month, as well as 400,000 GB-seconds....
Hoisting is a concept in JavaScript where the language moves all function and variable declarations to the top of their scope before executing the code. This means that regardless of where functions or variables are declared in the code, they can be used before they have been declared. However, it’s important to note that hoisting behaves differently for function declarations and function expressions. For function declarations, you can call a function before it’s defined without any issues....

HTTP cookies are a fundamental aspect of the Web that enable sessions and help recognize users during their browsing experience. Introduction Cookies allow the exchange of information between the server and the browser, making it possible to customize user sessions and enable servers to identify users across requests. HTTP is a stateless protocol, meaning that all requests to a server are treated the same, and the server cannot distinguish between a new request and a subsequent request from a client....
In JavaScript, comparison operators are used to compare two values and determine their relationship. These operators return a boolean value, either true or false, based on the comparison result. This article will cover the basic comparison operators in JavaScript and provide examples of their usage. Less Than (<) Operator The less than operator (<) checks if the value on the left is smaller than the value on the right. It returns true if the condition is met, otherwise false....
