How do the CSS properties table-layout and width interact when styling a table?
Difficulty level
They work independently of each other.
table-layout determines how widths are calculated.
table-layout overrides width.
width only applies if table-layout is set to fixed.
The table-layout property determines the algorithm used to lay out table cells, rows, and columns. When it's set to auto (the default), the browser calculates the width of the table and its cells to fit the content. When set to fixed, column widths are set by the width of the first row of cells, the table's width, and any specified column widths. Using fixed can allow for faster rendering in large tables.
How does the preload attribute in the audio or video tags affect the loading of multimedia content?
Difficulty level
It forces the media to play repeatedly.
It sets the initial volume of the media.
It sets the starting time of the media playback.
It specifies if/how the media should be loaded when the page loads.
The preload attribute in the audio or video tags provides hints to the browser about how the media file should be preloaded. There are three values it can take: "none" (means the media should not be preloaded), "metadata" (only metadata should be loaded), and "auto" (the media should be loaded entirely or up to a browser-defined limit). This helps optimize the user experience by potentially reducing load times or unnecessary data usage.
You're developing a webpage where clicking on a product image should navigate to the product's detailed view in a new tab, ensuring the original page remains open. How would you implement this using anchor tags and target attributes?
Difficulty level
Use target="_blank" in the anchor tag.
Use target="_parent" in the anchor tag.
Use target="_self" in the anchor tag.
Use target="_top" in the anchor tag.
The target="_blank" attribute in the anchor tag makes the linked document open in a new browser window or tab. This ensures the original page remains open while the user can view the product details in a new tab.
How does the tag semantically differ from the tag in HTML?
Difficulty level
Both and tags have the same semantic meaning.
The tag is deprecated, and the tag is the modern replacement.
The tag is used for emphasis, while the tag is used for italicizing text.
The tag is used for italicizing text, while the tag is used for emphasis.
The tag is used to emphasize text, indicating that the enclosed text has a different mood or tone compared to surrounding text. On the other hand, the tag is primarily a stylistic element that italicizes text without any added semantic meaning. While browsers traditionally render both as italic, the key difference lies in their intended purpose: is for semantic emphasis, while is for style.
How is the element typically used within a web page?
Difficulty level
To define a section header.
To describe the content of a element.
To provide a legend for a table.
To style text with CSS.
The element is meant to be used as a container for brief explanations or captions associated with the
element. It is typically placed as the first or the last child of a
, helping to provide context or further description for the enclosed content, especially when the figure is referenced from the main content.
You have a form with various input fields. How would you utilize the "required" and "placeholder" attributes to enhance user experience?
Difficulty level
Use "placeholder" to indicate mandatory fields and "required" to give an example.
Use "required" for every field and "placeholder" for decorative purposes.
Use "required" on non-mandatory fields and "placeholder" to show actual data.
Use "required" to indicate mandatory fields and "placeholder" to give a hint or example input.
The "required" attribute ensures that an input field must be filled out before submitting the form. The "placeholder" attribute provides a short hint or an example input to guide the user on what to type, but it disappears once the user starts typing. These attributes together enhance usability by guiding the user through form completion and ensuring necessary data is provided.
