Free Front-End Development Course Questions and Answers — Questions and Answers
Question 1: Where exactly should a reference to an external style sheet be made in an HTML document?
- In the footer section
- In the body section
- At the end of the document
- In the head section (Correct answer)
Correct answer: In the head section
External stylesheets are linked to an HTML document using the `<link>` tag, which must always be placed within the `<head>` section of the HTML document. Placing it here ensures that the browser loads and applies the styles before rendering the page content. This prevents a 'flash of unstyled content' and ensures the page displays correctly from the start.
Question 2: The people who create Web standards.
- The World Wide Web Consortium (Correct answer)
- Microsoft
- IBM
- Mozilla
Correct answer: The World Wide Web Consortium
The World Wide Web Consortium (W3C) is an international community that develops open standards to ensure the long-term growth and interoperability of the Web. They are responsible for creating and maintaining many of the core web technologies, including HTML, CSS, and XML. This standardization ensures that web content and applications function consistently across different browsers and devices.
Question 3: What is the acronym for HTML?
- Hyper Text Markup Language (Correct answer)
- Home Tool Markup Language
- Hyperlinks and Text Markup Language
Correct answer: Hyper Text Markup Language
HTML stands for Hyper Text Markup Language. It is the standard markup language used to create web pages and web applications. HTML describes the structure of a web page semantically, using tags to define elements like headings, paragraphs, images, and links, which browsers then interpret and display.
Question 4: What is the acronym for CSS?
- Creative Style Sheets
- Computer Style Sheets
- Colorful Style Sheets
- Cascading Style Sheets (Correct answer)
Correct answer: Cascading Style Sheets
CSS stands for Cascading Style Sheets. It is a stylesheet language used for describing the presentation of a document written in HTML or XML. CSS allows developers to control the layout, colors, fonts, and other visual aspects of web pages, effectively separating content from its visual presentation.
Question 5: How may a numbered list be created?
- nl
- dl
- ol (Correct answer)
- ul
Correct answer: ol
In HTML, an ordered list, which is a numbered list, is created using the `<ol>` tag. The 'ol' stands for 'ordered list.' Each item within this list is then defined using the `<li>` (list item) tag, and the browser automatically renders these items with sequential numbers.
Question 6: What HTML code should be used to create a text input field?
- textfield
- text
- input type="textfield"
- input type="text" (Correct answer)
Correct answer: input type="text"
To create a single-line text input field in HTML, the `<input>` tag is used with its `type` attribute set to 'text'. This specific attribute value tells the browser to render a standard text box where users can enter alphanumeric data. Other `type` values create different kinds of input fields, such as 'password' or 'email'.
Question 7: JavaScript is identical to Java.
- Yes
- No (Correct answer)
- Why not
Correct answer: No
No, JavaScript and Java are two distinct and unrelated programming languages, despite their similar names. Java is a compiled, object-oriented language often used for enterprise-level applications and Android development, while JavaScript is an interpreted scripting language primarily used for front-end web development to add interactivity to web pages. Their syntax, execution environments, and typical use cases differ significantly.
