Emmet in Visual Studio Code
Support for Emmet snippets and expansion is built right into Visual Studio Code, no extension required. Emmet 2.0 has support for the majority of the Emmet Actions including expanding Emmet abbreviations and snippets.
How to expand Emmet abbreviations and snippets
Emmet abbreviation and snippet expansions are enabled by default in html
, haml
, pug
, slim
, jsx
, xml
, xsl
, css
, scss
, sass
, less
and stylus
files, as well as any language that inherits from any of the above like handlebars
and php
.
When you start typing an Emmet abbreviation, you will see the abbreviation displayed in the suggestion list. If you have the suggestion documentation fly-out open, you will see a preview of the expansion as you type. If you are in a stylesheet file, the expanded abbreviation shows up in the suggestion list sorted among the other CSS suggestions.
Using Tab for Emmet expansions
If you want to use the Tab
key for expanding the Emmet abbreviations, add the following setting:
"emmet.triggerExpansionOnTab": true
This setting allows using the Tab
key for indentation when text is not an Emmet abbreviation.
Emmet when quickSuggestions are disabled
If you have disabled the editor.quickSuggestions
setting, you won't see suggestions as you type. You can still trigger suggestions manually by pressing Ctrl+Space
and see the preview.
Disable Emmet in suggestions
If you don't want to see Emmet abbreviations in suggestions at all, then use the following setting:
"emmet.showExpandedAbbreviation": "never"
You can still use the command Emmet: Expand Abbreviation to expand your abbreviations. You can also bind any keyboard shortcut to the command id editor.emmet.action.expandAbbreviation
as well.
Emmet suggestion ordering
To ensure Emmet suggestions are always on top in the suggestion list, add the following settings:
"emmet.showSuggestionsAsSnippets": true,
"editor.snippetSuggestions": "top"
Emmet abbreviations in other file types
To enable the Emmet abbreviation expansion in file types where it is not available by default, use the emmet.includeLanguages
setting. Make sure to use language identifiers for both sides of the mapping, with the right side being the language identifier of an Emmet supported language (see the list above).
For example:
"emmet.includeLanguages": {
"javascript": "javascriptreact",
"razor": "html",
"plaintext": "pug"
}
Emmet has no knowledge of these new languages, and so there might be Emmet suggestions showing up in non HTML/CSS contexts. To avoid this, you can use the following setting.
"emmet.showExpandedAbbreviation": "inMarkupAndStylesheetFilesOnly"
Note: If you used
emmet.syntaxProfiles
previously to map new file types, from VS Code 1.15 onwards you should use the settingemmet.includeLanguages
instead.emmet.syntaxProfiles
is meant for customizing the final output only.
Emmet with multi-cursors
You can use most of the Emmet actions with multi-cursors as well:
Using filters
Filters are special post-processors that modify the expanded abbreviation before it is output to the editor. There are 2 ways to use filters; either globally through the emmet.syntaxProfiles
setting or directly in the current abbreviation.
Below is an example of the first approach using the emmet.syntaxProfiles
setting to apply the bem
filter for all the abbreviations in HTML files:
"emmet.syntaxProfiles": {
"html": {
"filters": "bem"
}
}
To provide a filter for just the current abbreviation, append the filter to your abbreviation. For example, div#page|c
will apply the comment
filter to the div#page
abbreviation.
BEM filter (bem)
If you use the Block Element Modifier (BEM) way of writing HTML, then bem
filters are very handy for you to use. To learn more about how to use bem
filters, read BEM filter in Emmet.
You can customize this filter by using the bem.elementSeparator
and bem.modifierSeparator
preferences as documented in Emmet Preferences.
Comment filter (c)
This filter adds comments around important tags. By default, "important tags" are those tags with id and/or class attribute.
For example div>div#page>p.title+p|c
will be expanded to:
<div>
<div id="page">
<p class="title"></p>
<!-- /.title -->
<p></p>
</div>
<!-- /#page -->
</div>
You can customize this filter by using the filter.commentTrigger
, filter.commentAfter
and filter.commentBefore
preferences as documented in Emmet Preferences.
The format for the filter.commentAfter
preference is different in VS Code Emmet 2.0.
For example, instead of:
"emmet.preferences": {
"filter.commentAfter": "\n<!-- /<%= attr('id', '#') %><%= attr('class', '.') %> -->"
}
in VS Code, you would use a simpler:
"emmet.preferences": {
"filter.commentAfter": "\n<!-- /[#ID][.CLASS] -->"
}
Trim filter (t)
This filter is applicable only when providing abbreviations for the Emmet: Wrap with Abbreviation command. It removes line markers from wrapped lines.
Using custom Emmet snippets
Custom Emmet snippets need to be defined in a json file named snippets.json
. The emmet.extensionsPath
setting should have the path to the directory containing this file.
Below is an example for the contents of this snippets.json
file.
{
"html": {
"snippets": {
"ull": "ul>li[id=${1} class=${2}]*2{ Will work with html, pug, haml and slim }",
"oll": "<ol><li id=${1} class=${2}> Will only work in html </ol>",
"ran": "{ Wrap plain text in curly braces }"
}
},
"css": {
"snippets": {
"cb": "color: black",
"bsd": "border: 1px solid ${1:red}",
"ls": "list-style: ${1}"
}
}
}
Authoring of Custom Snippets in Emmet 2.0 via the snippets.json
file differs from the old way of doing the same in a few ways:
Topic | Old Emmet | Emmet 2.0 |
---|---|---|
Snippets vs Abbreviations | Supports both in 2 separate properties called snippets and abbreviations | The 2 have been combined into a single property called snippets. See default HTML snippets and CSS snippets |
CSS snippet names | Can contain : | Do not use : when defining snippet names. It is used to separate property name and value when Emmet tries to fuzzy match the given abbreviation to one of the snippets. |
CSS snippet values | Can end with ; | Do not add ; at end of snippet value. Emmet will add the trailing ; based on the file type (css/less/scss vs sass/stylus) or the emmet preference set for css.propertyEnd , sass.propertyEnd , stylus.propertyEnd |
Cursor location | ${cursor} or | can be used | Use only textmate syntax like ${1} for tab stops and cursor locations |
HTML Emmet snippets
HTML custom snippets are applicable to all other markup flavors like haml
or pug
. When snippet value is an abbreviation and not actual HTML, the appropriate transformations can be applied to get the right output as per the language type.
For example, for an unordered list with a list item, if your snippet value is ul>li
, you can use the same snippet in html
, haml
, pug
or slim
, but if your snippet value is <ul><li></li></ul>
, then it will work only in html
files.
If you want a snippet for plain text, then surround the text with {}
.
