HTML Interview Questions and Practice Challenges
# HTML Interview Questions and Practice Challenges
1. Introduction
You've made it to the end of the HTML course! To solidify your knowledge and prepare for job interviews, this chapter compiles the most common interview questions and practical coding challenges.2. Top Interview Questions
Q1: What does HTML stand for? A: HyperText Markup Language.
Q2: What is the difference between a block-level element and an inline element?
A: A block-level element always starts on a new line and takes up the full width available (e.g., <div>, <p>, <h1>). An inline element does not start on a new line and only takes up as much width as necessary (e.g., <span>, <a>, <img>).
Q3: What are Semantic HTML tags and why do we use them?
A: Semantic tags clearly describe their meaning to both the browser and the developer. Examples include <header>, <footer>, <article>, and <nav>. We use them to improve accessibility (for screen readers) and SEO (Search Engine Optimization).
Q4: What is the purpose of the alt attribute on an image?
A: It provides alternative text for the image if it fails to load, and it is read aloud by screen readers for visually impaired users.
Q5: Difference between id and class?
A: An id must be unique in the HTML document and targets a single element. A class can be used on multiple elements to group them for styling.
Q6: What is the doctype declaration for HTML5?
A: <!DOCTYPE html>
Q7: How do you open a link in a new tab?
A: Add the target="_blank" attribute to the <a> tag.
