The :first-letter pseudo-element can be used to create common typographical effects, such as drop caps. Drop caps is the effect obtained when the first character of a paragraph is rendered in a font larger than the rest, and its baseline is lowered by at least one full line, which results in the second line of the text also being indented.

The :first-letter pseudo-element can be attached to block-level elements. It can be attached to inline elements if you set the corresponding display property to block.

Examples

The following examples show how to use the :first-letter pseudo-element.

The following rule causes the first letter in the paragraph to be a drop cap that is twice the size of the other letters in the paragraph.

</STYLE>
<P CLASS="BigFirst">The first letter in this paragraph will be
twice the size of the other letters in this paragraph.  The first
letter in this paragraph will be twice the size of the other
letters in this paragraph.</P>
