Tips

• A positive value creates a typical paragraph indent and serves as a visual clue as to where new paragraphs begin.

• A negative value creates a hanging indent. You may need to increase the padding (see page 177) or margins (see page 176) around a text box with a hanging indent in order to accommodate the overhanging text.

  Figure 10.30. Each paragraph is indented 21 pixels.

  

• Em values, as usual, are calculated with respect to the element's font size. Percentages are calculated with respect to the width of the parent element.

• The text-indent property is inherited.

• If you use a percentage or an em value, only the resulting size (or "computed value") is inherited. So, if the parent is 300 pixels wide, a text-indent of 10% will be 30 pixels. And all child elements will also have their first lines indented 30 pixels, regardless of the width of their respective parents.

• Use a value of 0 to remove an inherited indent. For example, you might want to create a special class for the first paragraph in each section and set its text indent to 0.
