  • id 
  • type 
  • value 
The id attribute is used to give a unique identifier to an HTML element. This unique id can be referred to from the CSS, JavaScript, or for linking to a specific section of a webpage. Each id should be unique within a page to ensure precise referencing.

Can a
element be used without a
? If so, in what scenarios?

  • No, they always come together. 
  • Yes, when the content is self-explanatory. 
  • Yes, when the figure is used inside an article. 
  • Yes, when using multiple images. 
The

element can absolutely be used without a
. It's not mandatory to have a caption for every figure. If the content inside the

is self-explanatory or if a caption might be redundant or unnecessary, one can omit the
. However, when context or an explanation is beneficial, then
should be included.

How does the placement of "thead" and "tfoot" in the code affect the visual rendering of the table?

  • "tfoot" can never be visually rendered by browsers. 
  • Only "thead" affects the rendering, "tfoot" is ignored. 
  • The "thead" always renders at the top and "tfoot" at the bottom, regardless of their positions in the code. 
  • They render in the order they appear in the code. 
Despite the placement of "thead" and "tfoot" in your HTML code, visually, browsers always render "thead" at the top and "tfoot" at the bottom of the table. This ensures that header and footer information is consistently displayed in the correct locations, even if the code sequence differs.

Providing a _____ property value for an interactive HTML element ensures that it is included in the tabbing navigation.

  • display 
  • tabindex 
  • visibility 
  • z-index 
The tabindex attribute in HTML specifies the tab order of an element. A positive value ensures the element is focusable in sequential keyboard navigation. It's particularly important for making interactive elements accessible to keyboard users. If an element should be focusable but not in the sequential keyboard flow, tabindex="0" can be used.

What is the primary purpose of using comments in HTML?

  • To add interactivity to a webpage. 
  • To give instructions to the browser. 
  • To provide explanations or notes within the code for developers. 
  • To style the webpage. 
Comments in HTML are primarily used as a tool for developers. They allow coders to leave notes, explanations, or annotations within the code, helping to make the code more understandable and maintainable for other developers who might work on the same project. While comments don't impact the display or functionality of a webpage, they are invaluable for teamwork and understanding the logic behind specific code sections.

The _______ CSS property is used to control the line-breaking behavior of an inline element.

  • border-collapse 
  • display 
  • line-height 
  • white-space 
The white-space CSS property determines how white spaces inside an element are handled. By default, it's set to normal, which allows white spaces to collapse and line breaks to occur. However, if you want to control the line-breaking behavior of an inline element (like preventing it from breaking), you can use values like nowrap for the white-space property.

The _______ element should be used to provide a reference for a blockquote when it is not part of the quoting sentence.

  • cite 
  • figcaption 
  • ref 
  • source 
The figcaption element is typically used with the

element to provide a caption or a reference for content such as

, images, or diagrams. When a blockquote needs additional context or a citation that isn't part of the quoting sentence, wrapping the blockquote in a

and using a
for the citation/reference provides a semantically meaningful structure.

When implementing responsive tables for mobile views, the CSS property ______ is commonly used to display content in a block-level format.

  • display: block; 
  • position: relative; 
  • table-display: mobile; 
  • visibility: hidden; 
To make tables responsive, especially for mobile views where screen real estate is limited, the display: block; property can be employed. This takes the table out of its default table display context and makes it behave like a block-level element. This is often combined with media queries and other techniques to stack rows or reformat the table structure for better mobile readability.

What is the purpose of the tag in HTML tables?

  • It allows merging of table cells. 
  • It defines a cell that contains column headings. 
  • It provides a title or summary for the table. 
  • It specifies cell padding. 
The

tag is used to provide a title or a summary for an HTML table. It helps give context and improve the accessibility of the table by informing users about the table's content or purpose at a glance. Typically, the caption will be centered above the table.

You're building a navigation menu using inline elements. How would you ensure that they are spaced evenly and are also responsive?

  • Assign a percentage-based width to each element. 
  • Set a fixed width and use margin: auto; 
  • Use flexbox with justify-content: space-between; 
  • Use tables for layout. 
Using Flexbox is one of the modern approaches to layout designs and is very effective in spacing elements evenly within a container. By setting the container to display: flex; and using justify-content: space-between;, you can ensure that the inline elements (like navigation links) are spaced evenly. Additionally, Flexbox is responsive by nature, allowing for adjustments based on different viewport sizes.
