Languages
HTML
Tag completion, closing-tag sync, and awareness of linked CSS and JavaScript in HTML documents.
Editing HTML
Built-in HTML features cover .html and related markup. You get tag and
attribute completion, matching close tags as you type, and hover notes for
common elements.
Emmet abbreviations
In HTML, and in many template languages, Emmet abbreviations expand with
Tab. For example, ul>li*3 becomes a list. See
Emmet for profiles and custom snippets.
Linked styles and scripts
Path completion helps when you type href and src. Opening a linked
stylesheet or script can jump the way go-to-definition does, when the
language service can resolve the path.
Formatting
Format Document uses the HTML formatter settings under HTML › Format. Turn on Format on Save if you want each save to tidy the markup.
