How does the browser render a table when the "tfoot" element is written before the "tbody" element in the HTML code?
Difficulty level
The "tfoot" is displayed at the top of the table.
The "tfoot" is ignored.
The browser moves the "tfoot" to appear after the "tbody".
The table gets distorted.
Even if the "tfoot" is written before the "tbody" in the HTML markup, browsers will render the "tfoot" section below the "tbody". This behavior ensures that footers appear at the bottom of tables, irrespective of their position in the code. It's an example of the browser's fault-tolerant behavior with the HTML specification.
How can you ensure that image maps are accessible to users using screen readers?

By avoiding the use of image maps.
By enlarging the active areas.
By providing alternative text for each active area.
Ensuring accessibility in web content is crucial, especially for users relying on screen readers.

This ensures that users with visual impairments can understand and interact with the content effectively.

Can two stylesheets be linked in the head section and how would they be applied?
Difficulty level
No, only one stylesheet is allowed.
No, stylesheets must be included in the body section.
Yes, and they will be applied in the order they appear.
Yes, and they will override each other.
Yes, multiple stylesheets can be linked in the head section of an HTML document. They will be applied in the sequence they appear. If there are conflicting styles, the rules in the later stylesheet will override those in the earlier ones. This allows for flexibility in web design, where base styles can be established in one sheet, and theme-specific or module-specific styles can be layered on top in subsequent sheets.
To create a nested list in HTML, you can place a complete list (
or
) inside a list item (
) of another list. This allows you to have sub-lists or multi-level lists on your webpage. The browser will typically indent the nested list to indicate the hierarchy.
In what way can a navigational list be made accessible for screen reader users?
Difficulty level
Embed audio descriptions for each item.
Make all items flash on focus.
Use ARIA roles and proper semantic tags.
Use larger font sizes for the list items.
ARIA (Accessible Rich Internet Applications) roles and attributes provide additional information about how elements behave or are related, enhancing the experience for users of assistive technologies. For navigation lists, using semantic HTML tags like
On a recipe website, you need to list the ingredients and steps separately and also allow for a nested list under some of the steps. How would you utilize ordered and unordered lists to structure the content?
Difficulty level
Use
for ingredients and steps with nested
for nested lists.
Use
for ingredients and
for steps.
Use
for steps and
for ingredients, with nested
under steps when necessary.
Use only
for both ingredients and steps.
For a recipe, the order of steps is critical, so
(ordered list) is the best choice. For ingredients, since the order is typically not as vital,
(unordered list) is more appropriate. In cases where a step may have sub-steps or additional details, a nested
can be used under the primary
to maintain clarity and structure.
