It hides any text that goes outside the container's width, so the extra text is not visible beyond the box edges.

What is the role of whitespace-nowrap in truncating text?

It prevents the text from breaking into multiple lines, forcing it to stay on one line so truncation can happen.

Why is it important to set a fixed width or max-width when using text truncation?

Without a fixed width, the container can grow with the text, so truncation won't happen. Setting width limits the space so overflow triggers truncation.

Which Tailwind class adds an ellipsis to overflowing text?

A whitespace-normal

B overflow-visible

C truncate

D text-ellipsis

The truncate class adds an ellipsis (...) to text that overflows its container.

What does whitespace-nowrap do in Tailwind CSS?

A Prevents text from wrapping to new lines

B Allows text to wrap to multiple lines

C Adds space between words

D Makes text bold

whitespace-nowrap keeps text on one line by preventing wrapping.

Which combination of classes is needed to truncate text properly?

A overflow-visible, whitespace-normal, truncate

B overflow-hidden, whitespace-nowrap, truncate

C overflow-scroll, whitespace-nowrap, truncate

D overflow-hidden, whitespace-normal, truncate

You need overflow-hidden, whitespace-nowrap, and truncate together for proper truncation.

Why must the container have a fixed width for truncation to work?

A To center the text

B To allow text to wrap

C To make text bold

D To limit space so overflow triggers truncation

A fixed width limits the container size, causing overflow and enabling truncation.

What happens if you omit overflow-hidden when truncating text?

A Text will overflow visibly outside container
