The size of text is measured in points. There are 72 points per inch, so an uppercase letter set in 11 point type is about 5/32″ tall, as shown in Figure 4-21. Other text formatting options that can be set in the Home Font area of the ribbon include bold, italic, underline, strikethrough, subscript, superscript, and color. Bold, italic, and underline are discussed earlier in this chapter. Strikethrough is a horizontal line through the middle of characters. Click the Strikethrough button to format the selected text as strikethrough. Superscript is formatting that sets the character smaller than normal and raised, such as the 2 in X2. Click the Superscript button to make the selected text superscript. Subscript is formatting that sets the character smaller than normal and lowered, such as the 1 in Y 1 . Click the Subscript button to make the selected text subscript. To change the color of the selected text, click the drop-down arrow next to the Font Color button, and select a new color in the palette that is displayed. Styles A more effi cient and complete method of formatting text is using styles. A style is a group of formatting settings that can be applied in one step. The look of text can be quickly changed by picking a new style. It immediately changes the typeface and paragraph properties of the text. For text documents, there are two basic types of styles: paragraph and character. A paragraph style defi nes the formatting for a paragraph, including the text formatting. A character style defi nes the text formatting for individual characters. Paragraph-related formatting, such as margins and indents, are not part of a character style. To see a list of the available styles in Microsoft Word, click Home Styles More on the ribbon, as shown in Figure 4-22. Clicking a style name in the gallery immediately applies the formatting defi ned in the style to the selected text.
