Question

What would this CSS rule do?

h2  {  font-size: 2em;
    }

Options

• Make fonts in a specific h2 tag double in size.

• Make fonts in all h2 tags double in size.

• Make fonts in all h2 tags double in size and italic.

• Make all fonts that are size 2, empty.

Answer 1

Make fonts in all h2 tags double in size.

Explanation:

The rule is broken down as follows:

• All <h2> elements are targeted by the CSS selector h2. <h2> in HTML denotes a heading level 2.
• The declaration block, which has one or more property-value pairs, is enclosed by {}.
• The declaration block has a property-value pair called font-size:2em;. The font-size property is set to 2em. The font size will be double that of the normal font size if the value is 2em.

Therefore, all heading level 2 elements (<h2>) would be shown with a font size that is double the default font size if this CSS rule were applied to an HTML page.
