Optional Attributes
There are no optional attributes for the abbr element apart from the standard global attributes.
The small element indicates a side note or fine print relating to the main text. This might be a disclaimer,
clarification, citation, attribution, restriction, or a copyright or licensing notice. It's not intended for long
passages of text, only short phrases inline with other text, or sometimes in a footnote at the end of an
article or document. The small element indicates that its contents are supplemental to the main text but
not any less important, and a small doesn't serve to “de-emphasize” phrases within a passage already
emphasized by the em or strong elements.
This element is a carryover from past versions of HTML, where it was essentially a presentational element
that only denoted small text. Authors often used the small element for such fine print, and so HTML5 has
adopted and standardized that practice, giving the element more semantic purpose. Use the small
element to include these meaningful notes in your content, but don't use it just to make your text appear
smaller; that would be presentational markup.
Previous versions of HTML offered a counterpart big element, which only denoted
larger text and served no purpose beyond presentation. The big element is obsolete in
Listing 4-34 shows a small element marking an inline disclaimer.

As you'd probably expect, browsers render the contents of a small element at a slightly smaller font size
than the adjacent text (see Figure 4-21). This is proportional to the font size of the parent element; if you
declare a large font size in your style sheet for the parent element, a small will be slightly smaller than
that, whatever that size happens to be.
