Identify the CSS property that specifies the length of the space used for the tab character.

The correct answer is: B. tab-size

The CSS property tab-size specifies the length of the space used for the tab character. It is a length value, which can be expressed in any of the following ways:

• A number, followed by a unit of length, such as 1em or 20px.
• A percentage, such as 50%.
• A keyword, such as normal or inherit.

The default value of tab-size is 4, which means that a tab character will take up four spaces.

The following example shows how to use the tab-size property to set the length of the space used for the tab character:

css
p {
tab-size: 2em;
}

In this example, the p element will use a tab character that is two ems wide.

The size property is used to specify the font size. It is a length value, which can be expressed in any of the following ways:

• A number, followed by a unit of length, such as 1em or 20px.
• A percentage, such as 50%.
• A keyword, such as normal or inherit.

The default value of size is 16px.

The tab-space property is not a valid CSS property.
