Defining HTML Abbreviations

When the abbreviation (or acronym) is little-known, simply deciphering it might not be enough: you might need to provide some extra explanation. To do that, nest your <abbr> tags inside a <dfn> element:

<p><dfn id="evm"><abbr title="Ethereum Virtual Machine">EVM</abbr>
</dfn> is a blockchain-based software platform. </p>

Let's analyze the example above bit by bit:

• The <abbr> tags note that EVM is an HTML abbreviation.
• The <dfn> tags show that EVM is a term being defined.
• The title attribute defines the full term EVM represents.
