Name

Emmet is a word that originally meant ant, a small insect that can carry over 50 times of its weight. This word is also similar to "emit," which is basically what Emmet does when it expands abbreviations.


Functions


Expand abbreviations

Emmet uses a specific syntax in order to expand small snippets of code, similar to CSS selectors, into full-fledged HTML code. For example, the sequence div#page>div.logo+ul#navigation>li*5>a or #page>.logo+ul#navigation>li*5>a expands into
The expand abbreviations function includes several other complex functions, such as wrapping a section of code with expanded code.


Tag balancing

The HTML Pair Matcher allows users to locate the matching open/close tag for the tag at the current cursor position. Unlike other HTML pair matchers, Emmet searches from the cursor's current position rather than scanning the document from the beginning.
