What does the DOCTYPE declaration do in an HTML document?

Informs the web browser about the version of HTML being used.
Initiates the JavaScript engine in the web browser.
Defines the character encoding of the document.

Specifies the CSS file linked to the HTML document.

Explanation and Hint:

The DOCTYPE declaration tells the browser which version of HTML to expect, helping it render the page correctly. It does not affect the content itself but ensures proper document structure.

What is the main difference between inline and block-level elements in HTML?

Block-level elements start on a new line and take up the full width available, whereas inline elements do not start on a new line and only take up as much width as necessary.
Inline elements are primarily used for content that is part of a paragraph, such as links, while block-level elements structure the main parts of a page, like sections and articles.
Block-level elements are used for styling while inline elements are used for structuring content.
Inline elements are removed from the normal flow of the document, whereas block-level elements remain within the flow.

Explanation and Hint:

Block-level elements, like <div> and <p>, start on a new line and occupy the full width of their container, while inline elements, like <span> and <a>, flow within the content without breaking the line.

What is the main purpose of the <head> section in an HTML document?

To contain metadata and instructions for the browser.
To display visible content to the user.
To define the footer of the web page.
To include the main navigation links.

Explanation and Hint:

The <head> section includes information like the document’s title, character encoding, linked stylesheets, and scripts, which help the browser process and display the page correctly but are not visible to the user.

How do you comment out a section of code in HTML?
- By using // at the beginning of each line.
- By wrapping the section with /* and */.
- By enclosing the section with .
- By enclosing the section with <!- and ->.
- Explanation and Hint:
  
  In HTML, comments are written by wrapping the text with <!– at the beginning and –> at the end, making it ignored by the browser but visible in the source code.

What role does CSS play in web development?

Adds interactivity to the web page.
Provides the basic structure and content.
Connects the web page to the server.
Defines the presentation of HTML content.

Explanation and Hint:

CSS (Cascading Style Sheets) controls the layout, colors, fonts, and overall appearance of HTML elements, enhancing the visual presentation of a web page without altering its content.

Which tag is necessary to include JavaScript code in an HTML document?

<code>
<js>
<script>
<javascript>

Explanation and Hint:

The <script> tag is used to include JavaScript code in an HTML document. It can be placed in the head or body section and can either contain inline JavaScript or link to an external JavaScript file.

How is the Document Object Model (DOM) utilized in web development?
- It allows developers to dynamically manipulate the content and structure of web pages.
- It stores the server-side scripts used in the webpage.
- It encrypts data sent between the client and server.
- It defines the color and style of the webpage elements.
- Explanation and Hint:
  
  The DOM represents the structure of a webpage as a tree of objects, enabling developers to access, modify, or delete elements and content dynamically using JavaScript.
Which HTML element is used to link a webpage to an external CSS file named “styles.css”?
- <css src="styles.css">
- <link rel="stylesheet" href="styles.css">
- <stylesheet file="styles.css">
- <style src="styles.css">
- Explanation and Hint:
  
  The <link> tag with rel=”stylesheet” and href=”styles.css” is used to link an external CSS file to an HTML document.

Examine the following HTML snippet:

<html lang="en">

What is the purpose of the `lang` attribute in the `<html>` tag?

Defines the language of the document’s content for search engines and screen readers.
Specifies the character encoding of the document.
Automatically translates the document content to the specified language.
Specifies the default language of the web page and changes the text direction of the document to support languages written from left to right.

Explanation and Hint:

The lang attribute in the <html> tag specifies the primary language of the content, which helps search engines and screen readers correctly interpret and present the text.

What is the function of the `<meta charset="UTF-8">` tag in an HTML document?

It sets the entire document’s font to the UTF-8 style, overriding any CSS styling.
It encrypts the HTML document using UTF-8 encryption for security purposes.
It specifies that the HTML document can only be opened using browsers that support UTF-8 encoding.
It defines the character encoding for the HTML document, ensuring that all characters are displayed correctly across different browsers and platforms.

Explanation and Hint:

The <meta charset=”UTF-8″> tag specifies the character encoding for the document, ensuring that characters from various languages are displayed correctly across different browsers and devices.

What is the role of the <html> tag in an HTML document?

It defines the metadata of the document, including the character encoding and viewport settings.
It indicates the beginning and end of an HTML document, encompassing all content within the document.
It is used to link external CSS files to style the HTML document.
It declares the document type and version of HTML being used.

Explanation and Hint:

The <html> tag is the root element of an HTML document and wraps all other content, including the <head> and <body> sections, marking the start and end of the document structure.

What distinguishes global attributes from element-specific attributes in HTML?

Global attributes can be applied to any HTML element for various purposes, such as styling and unique identification, while element-specific attributes are tailored to modify the behavior of specific elements.
Global attributes define the document’s structure, such as <header>, <footer>, and <article>, while element-specific attributes modify the document’s metadata like charset and viewport.
Global attributes are used exclusively within the <head> section of an HTML document to specify metadata, while element-specific attributes are used within the <body> section to define content properties.
Global attributes specify external resources required by the HTML document, such as CSS files and JavaScript scripts, whereas element-specific attributes are used to define inline styling and scripts.

Explanation and Hint:

Global attributes, like id, class, and style, can be used on any HTML element, whereas element-specific attributes, like href for <a> or src for <img>, are designed to provide functionality specific to the element they are applied to.

Do all HTML elements require a closing tag?

Closing tags are optional for all HTML elements as modern web browsers can automatically infer the end of elements.
Only HTML elements that contain other elements or content require a closing tag, while standalone elements do not.
No, not all HTML elements require a closing tag. Some elements, known as self-closing or void elements, do not need a closing tag, such as <img>, <br>, and <input>.
Yes, every HTML element must have a corresponding closing tag to ensure proper rendering by the web browser.

Explanation and Hint:

Some HTML elements, like <img>, <br>, and <input>, are self-closing or void elements, meaning they don’t require a closing tag. These elements are typically used to insert images, line breaks, or input fields into the document.

What best describes the difference between an HTML tag and an HTML element?

HTML tags are only used in the head section of a document, while HTML elements make up the body section.
An HTML tag is used to add content to a webpage, whereas an HTML element is used exclusively for styling purposes.
HTML elements are a new feature in HTML5, replacing the older system of HTML tags for better compatibility and efficiency.
An HTML element refers to the complete structure, including the opening tag, content, and closing tag, while a tag specifically denotes the opening and closing markers.

Explanation and Hint:

An HTML element includes the opening tag, the content between the tags, and the closing tag. A tag refers to the specific markers used to define elements, like <div> or </div>.
