Element-Specific Attribute
align
This attribute specifies the alignment of text within a paragraph. The default value is
left
. The transitional specification of HTML 4.01 also defines
center
,
justify
, and
right
. However, under the strict HTML and XHTML specifications, text alignment can be
handled through the CSS property
text-align
.
Examples
<p align="right">
A right-aligned paragraph
</p>
<p id="para1" class="defaultParagraph"
title="Introduction Paragraph">
This is the introductory paragraph for a very long paper about nothing.
</p>
Compatibility
HTML 2, 3.2, 4, 4.01, 5
XHTML 1.0, 1.1, Basic
Firefox 1+, Internet Explorer 2+,
Netscape 1+, Opera 2.1+, Safari 1+
Notes
• Because
p
is a block element, browsers typically insert a blank line, but this
rendering should not be assumed, given the rise of style sheets, which can use the
display
property to override this action.
• Under the strict (X)HTML and HTML5 specifications, the
align
attribute is not
supported. Alignment of text can instead be accomplished using CSS properties like
text-align
.
