currency is a simple microformat for marking up money amounts, such as prices of products/services or financial facts.

Property List

Examples

Simple in-line example with local definition of the currency unit: $39.99

<span class="money"><abbr class="currency" title="USD">$</abbr><span class="amount">39.99</span></span>

Text representation of the amount: Thirty-nine Dollars

<span class="money"><abbr class="amount" title="39">Thirty-nine</abbr> <abbr class="currency" title="USD">Dollars</abbr></span>

Example using the unit class: 99¢

<span class="money"><span class="amount">99</span><abbr class="unit">¢</abbr><abbr class="currency" title="USD"></abbr></span>

Table example with global definition of the currency:

   <table>
      <tr><th>Price in <abbr id="u1" class="currency" title="USD">US$</abbr></th></tr>
      <tr><td><div class="money">39.99<a href="#u1" class="include"></a></div></td></tr>
   </table>
