Given the following HTML:
<h1>The font-family Property</h1>
<p>The quick brown fox jumps over the lazy dog.</p>

Which CSS rule would ensure the heading displays at 16pt size?

Rationale

h1{font-size:16pt;}

This CSS rule correctly sets the font size of the `

` element to 16pt, ensuring that the heading displays at the desired size. The proper syntax for changing the font size uses the `font-size` property, which directly impacts the visual rendering of text.

A (#h1{font-size:16pt;}) YOUR ANSWER

This rule uses an ID selector (`#h1`), which is incorrect because it targets an element with a specific ID named "h1". The question specifies a tag selector for the heading element, not an ID, making this choice unsuitable.

B (h1{text-size:16pt;}) YOUR ANSWER

This option incorrectly uses the property `text-size`, which is not a valid CSS property. The correct property to set the font size is `font-size`, rendering this rule ineffective for changing the heading size.

C (#h1{text-size:16pt;}) YOUR ANSWER

Similar to choice A, this rule uses an ID selector (`#h1`) and also incorrectly employs the `text-size` property. Therefore, it fails to apply the intended font size to the heading, making it an invalid choice.

Conclusion

To ensure the heading displays at 16pt size, the correct CSS rule is `h1{font-size:16pt;}`. This rule employs the appropriate tag selector and uses the correct property, making it effective for achieving the desired text size. The other options either use incorrect property names or selectors that do not apply to the `

` element as specified in the question.
