I installed a new Emmet Abbreviation
plugin in my Sublime Text 3, by default the Syntax Scopes HTML are respectively these:
html
<html></html>
html:5 or !
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
</body>
</html>
however i would like to add or edit such certain Syntax. I already searched in Preferences> Package Settings> Emmet> Settings, but without success.
You need to redefine doc
snippet. In Emmet, snippets are abbreviations itself, or, in other words, snippets are aliases to another abbreviations.
