1. What is the web development trifecta?
Answer:

● The “web development trifecta” refers to HTML, CSS, and JavaScript:
○ HTML (HyperText Markup Language): Defines structure and content.
○ CSS (Cascading Style Sheets): Defines presentation and styling.
○ JavaScript: Defines interactivity and dynamic functionality in the browser.
Explanation: These three technologies work together to create modern web pages:
● HTML is the foundation for placing elements on a page.
● CSS determines how those elements look.
● JavaScript makes elements interactive (e.g., responding to clicks, animations).
2. What is the role of HTML in the web trifecta?
Answer:
● HTML gives the page structure by defining headers, paragraphs, images, links, and so
forth.
Explanation: Without HTML, there is no skeleton for your page’s content. HTML elements help
both browsers and assistive technologies understand the meaning of each section in a
document.
3. What is the role of CSS in the web trifecta?
Answer:
● CSS handles the presentation layer—visual styles, layout, color schemes, and fonts.
Explanation: While HTML places the content, CSS tells the browser how to display or style that
content, ensuring a clear separation of content from design.

4. What is the role of JavaScript in the web trifecta?
Answer:
● JavaScript brings dynamic behavior and interactivity to a webpage.
Explanation: JavaScript can manipulate the DOM (Document Object Model), respond to user
events like clicks or key presses, and fetch data asynchronously (AJAX), thereby enhancing
user experience.
5. How has HTML evolved to support modern design techniques?
Answer:
● HTML5 introduced semantic elements (<header>, <footer>, <main>, <section>, <nav>,
<article>, <aside>), multimedia tags (<video>, <audio>), and form enhancements (new
input types).
Explanation: These additions reduce reliance on external plugins (like Flash) and improve
accessibility and readability of the code.
6. Why is the doctype important?
Answer:
● The <!DOCTYPE html> declaration tells the browser to render the page in standards
mode, using HTML5 rules for parsing.
Explanation: Using the correct doctype reduces quirks-mode rendering issues and ensures
consistent behavior across modern browsers.
7. How is an ordered list created? An unordered list?
Answer:
Ordered list: <ol> with nested <li> elements.
