We recently examined <i> and <b>, presentational HTML4 elements that have been given a new lease on semantic life. Two more elements that have undergone transmogrification to receive semantics in HTML5 are <small> and <hr>:
<small>— was for smaller text, now used for side comments and small print (W3C:Markup, WHATWG)<hr>— was horizontal rule, now used for a paragraph-level thematic break in text (W3C:Markup, WHATWG)
The <small> element
The small element represents so-called “small print” such as legal disclaimers and caveats.
<small> is now for side comments, which are the inline equivalent of <aside> — content which is not the main focus of the page. A common example is inline legalese, such as a copyright statement in a page footer, a disclaimer, or licensing information. It can also be used for attribution. Don’t use it for block-level content (paragraphs, lists, etc.), as this would be considered main content.
<small class="font-license"> to fulfill the requirements of a font license agreement
<small><a rel="license" href="http://creativecommons.org/licenses/by-sa/3.0/">Creative Commons Attribution Share-alike license</a></small>
<small> around a Creative Commons license link with rel="license"<small> text does not need to be smaller than surrounding text — if all you want is smaller text use CSS instead. Use <small> only on inline content. Finally, <small> doesn’t affect the semantics of <em> or <strong>.
The <hr> element
The hr element represents a paragraph-level thematic break.
The “paragraph-level” bit means between blocks of text, so it can’t be used to separate sections of a site. Instead, After checking with Hixie I found I misinterpreted the paragraph content model (we regret the error!). I learned <hr> now separates different topics within a section of prose, or between scenes in a novel.<hr> actually means “end of one section, start of another
”, which is the same semantically as </section><section>. Because elements like <section> already indicate this intrinsically, <hr> is more for thematic breaks, such as separating different topics within a section of prose, or between scenes in a novel. However you can use it anywhere you can use a <p>. While not widely used these days (given the dull default browser renderings), it can be replaced via CSS with an image:
<hr> by removing borders and adding margins & a background image using CSS. For example;hr {height: 24px; background: url('flourish.png') no-repeat 50% 50%; margin: 3em 0; border: 0;}IE7 and lower live up to reputation by adding a border around the image regardless, but this can often be worked around. Alternatively you can just hide it via an IE7-and-lower stylesheet. Use a CSS border or background image on another element instead if the transition is obvious (for example between weblog comments), or the intended use is solely presentational.
<hr>.In summary
When HTML4 was released, the presentational elements <basefont>, <font>, <s>, <strike>, and <u> were already deprecated in favour of CSS. HTML5 completes this by removing <big> and <tt>.
The remaining HTML4 presentational elements — the long-ignored <small> and <hr> elements (along with <i> and <b> from last week) — have been redefined in HTML5 with useful, media-independent semantics that relate to their typical use. Will you be using them? Let us know in the comments!
