The colspan attribute in HTML is used when you want to merge two or more cells into a single cell horizontally in a table.

The _____ property in CSS is used to control the order of navigational elements when the tab key is used.
- order
- tab-order
- tabindex
- z-index
The tabindex property in CSS is used to specify the tab order of an element within a web page. A positive value defines the exact tab order, while a value of "0" means that the element should be focusable and reachable with the tab key. A negative value (like -1) makes the element focusable but not reachable via sequential keyboard navigation. It's essential for improving web accessibility and user navigation experience.Can the tags be placed outside the section?
- tags are not a part of HTML.
- No, they are exclusive to the section.
- They are only valid inside the
- Yes, they can be placed in the too.
tags provide metadata about the HTML document, like character set, viewport settings, or author information. These tags should be placed exclusively inside the section as they usually provide information to browsers or search engines about how to display or index the page, respectively.What is the purpose of the "legend" element within a fieldset?
- To act as a placeholder for inputs.
- To add a decorative line around the fieldset.
- To provide a caption or title for the group of controls inside the fieldset.
- To specify the method of form submission.
The legend element is used within a fieldset to provide a descriptive caption or title for the group of form controls contained inside that fieldset. It helps users understand the context or purpose of the information grouped together, thereby improving form usability and enhancing accessibility by providing context to users, especially those using assistive technologies.How can ARIA roles enhance the accessibility of form elements, particularly select lists?
- They can automatically complete form entries for users.
- They can define the specific nature and behavior of the select list, aiding screen readers.
- They change the visual design of the form to be more readable.
- They provide audible feedback when a user hovers over an element.
ARIA (Accessible Rich Internet Applications) roles provide additional semantic information about elements, particularly for assistive technologies like screen readers. By defining the specific nature and behavior of an element, ARIA roles enhance the accessibility and user experience for individuals with disabilities. For instance, a select list with an ARIA role can be identified and interacted with more easily by screen reader users, ensuring they can accurately navigate and understand the form's content.Which HTML element is used to define a short inline quotation?

Semantically, block-level elements should not be nested inside inline-level elements. Doing so can lead to unpredictable behavior in rendering and can also make the HTML document invalid. This practice goes against the standard document flow where block-level elements are used to structure the content while inline-level elements style specific parts within those blocks.
