Semantic tags, like `<header>`, `<nav>`, and `<footer>`, give meaning to the content, making it more accessible for search engines and screen readers.

Proposed Answer 2

They improve the readability of the code, help developers maintain projects, and enhance SEO by defining content structure clearly.

Proposed Answer 3

Semantic tags describe the purpose of the content, such as `<article>` for self-contained content, which benefits both browsers and users.

How do you create a form in HTML, and what key attributes are used in forms?

When to Ask: To test form creation knowledge.

Why Ask: Forms are essential for gathering user input on websites.

How to Ask: Ask for an explanation of the `<form>` tag and its key attributes.

Proposed Answer 1

A form is created using the `<form>` tag. Key attributes include `action` (specifies where data is sent), `method` (GET or POST), and `enctype` for data encoding.

Proposed Answer 2

Forms use input elements like `<input>`, `<textarea>`, and `<button>` for gathering data, while attributes like `required` and `placeholder` improve usability.

Proposed Answer 3

The `<form>` tag wraps input fields. Attributes like `name`, `id`, and `value` identify and process user input effectively.

What is the difference between inline, block, and inline-block elements?

When to Ask: To assess knowledge of element display behavior.

Why Ask: Understanding display types is critical for layout and design.

How to Ask: Ask for a definition of each and practical examples.

Proposed Answer 1

Block elements, like `<div>`, start on a new line and take up full width. Inline elements, like `<span>`, flow within text. Inline-block combines inline flow with block features.

Proposed Answer 2

Block elements are stackable, while inline elements don’t break the line. Inline-block allows styling like block elements without breaking the line.

Proposed Answer 3

Inline elements only occupy necessary space, block elements stretch to full width, and inline-block elements respect both width and height properties.

How does the `<meta>` tag affect SEO and page functionality?

When to Ask: To evaluate SEO-related HTML knowledge.

Why Ask: Meta tags improve page visibility and performance.

How to Ask: Ask the candidate to explain its role and key attributes.

How to Ask: Ask for specific tags and examples.

Proposed Answer 1

HTML5 provides the `<audio>` and `<video>` tags to embed media files directly without requiring plugins.

Proposed Answer 2

You can include media by specifying file paths in the `src` attribute of `<audio>` and `<video>` tags, with optional controls for playback.

Proposed Answer 3

HTML5 allows seamless multimedia integration using `<audio>` for sound and `<video>` for video, with support for formats like MP4 and WebM.

What is the difference between the `<div>` and `<span>` tags in HTML?

When to Ask: To evaluate the understanding of the structure and inline vs. block elements.

Why Ask: These tags are fundamental for layout and content organization.

How to Ask: Ask the candidate to explain the purpose and use cases for both tags.

Proposed Answer 1

The `<div>` tag is a block-level container used to group elements and structure layouts, while `<span>` is an inline container used for styling a small portion of text.

Proposed Answer 2

A `<div>` starts on a new line and takes up the full width, making it ideal for sections, whereas `<span>` doesn’t break the line and is used within text for styling.

Proposed Answer 3

Both tags are containers, but `<div>` is block-level for structural grouping, and `<span>` is inline, commonly used for applying styles or scripts to part of a sentence.

What are HTML attributes, and can you give examples of commonly used ones?

When to Ask: To evaluate knowledge of enhancing HTML elements with attributes.

Why Ask: Attributes are essential for adding functionality and meaning to elements.

How to Ask: Consider a definition and examples of commonly used attributes.

Proposed Answer 1

HTML attributes provide additional information about an element. Examples include `class` for styling, `id` for unique identification, and `src` for specifying media sources.

Proposed Answer 2

Attributes modify the behavior of HTML elements. Common ones are `href` for links, `alt` for image descriptions, and `style` for inline CSS.

Proposed Answer 3

Attributes like `title`, `disabled`, and `placeholder` help add context, improve accessibility, and control element behavior.

How does the `<iframe>` tag work, and what are its common use cases?

When to Ask: To test knowledge of embedding external content into a web page.

Why Ask: Understanding `<iframe>` is important for modern web integration tasks.

How to Ask: Request the candidate to explain the tag’s functionality and provide practical examples.
