💻 Using box shadow in a way you might not have expected
▪️ Here we create a box shadow with 0 blur and some offset to create a duplicate layer
▪️ Then we create a similar layer but a pixel more of spread, to create a pseudo border
▪️ Finally another actual box shadow layer
Box shadows in CSS can be layered. You can apply multiple box shadows for the same element. This is generally used for a rich and realistic box shadow, but what's stopping us hacking this 🤭

Here are some common frontend interview questions along with brief answers:
1. What is the DOM (Document Object Model)?
- Answer: The DOM is a programming interface for web documents. It represents the structure of a web page and allows scripts to dynamically access and update the content, structure, and style of a webpage.
2. Explain the difference between
- Answer:
3. What are closures in JavaScript?
- Answer: Closures are functions that remember the scope in which they were created, even after that scope has exited. They have access to variables from their containing function's scope.
4. Describe the differences between CSS Grid and Flexbox.
- Answer: CSS Grid is a two-dimensional layout system, while Flexbox is one-dimensional. Grid is used for overall layout structure, while Flexbox is ideal for distributing space and aligning items within a container along a single axis.
5. What is responsive web design, and how do you achieve it?
- Answer: Responsive web design is an approach to design and coding that makes web pages render well on various devices and screen sizes. Achieve it through media queries, flexible grids, and fluid images.
6. Explain the "box model" in CSS.
- Answer: The box model describes how elements on a web page are rendered. It consists of content, padding, border, and margin, and these properties determine the element's total size.
7. How does the event delegation work in JavaScript?
- Answer: Event delegation is a technique where you attach a single event listener to a common ancestor of multiple elements instead of attaching listeners to each element individually. Events that bubble up from child elements can be handled by the ancestor.
8. What is the purpose of the
- Answer: Both
9. Explain the same-origin policy in the context of web security.
- Answer: The same-origin policy is a security measure that restricts web pages from making requests to a different domain (protocol, port, or host) than the one that served the web page. It helps prevent cross-site request forgery (CSRF) and other security vulnerabilities.
10. What are the benefits of using a CSS preprocessor like Sass or Less?
- Answer: CSS preprocessors provide benefits such as variables, nesting, functions, and mixins, which enhance code reusability, maintainability, and organization. They allow you to write cleaner and more efficient CSS.

8. What is the purpose of the
localStorage and sessionStorage objects in JavaScript?- Answer: Both
localStorage and sessionStorage allow you to store key-value pairs in a web browser. The key difference is that data stored in localStorage persists even after the browser is closed, whereas data in sessionStorage is cleared when the session ends (e.g., when the browser is closed).9. Explain the same-origin policy in the context of web security.

🔰 Drop Cap In CSS
🔥 In CSS, this can be achieved through the initial-letter property, with a value indicating the number of lines to drop the character to
This property works only inside the ::first-letter pseudo element (and some other exceptions)
This also supports a multi value syntax of the format initial-letter: 3 2; where 2 indicated to have the baseline at line 2 (leave a gap of one line)
⚠️ This is not widely supported and required a vendor prefix to work in all browsers
Drop cap is a typography technique where the first letter of a new chapter is dropped to occupy multiple lines. You may be familiar with this through books!
