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:
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 ⌃Space (Windows, Linux 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:
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 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.For example:
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.
Note: If you used
emmet.syntaxProfiles
previously to map new file types, from VS Code 1.15 onwards you should use the setting emmet.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:
Include vendor prefixes
Prefix your CSS abbreviations with
-
to get all applicable vendor prefixes included in the expanded abbreviation.Below are a few examples of how you can control which vendors get applied to which CSS property by updating the
emmet.preferences
setting:- Setting the preference to a comma separated list of CSS properties will ensure that the corresponding prefix gets added only to those CSS properties.
- Setting the preference to an empty string will ensure that the corresponding prefix doesn't get added to any CSS property.
- Setting the preference to null will ensure that the default CSS properties for each vendor as documented in Emmet Preferences get used.
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: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: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:
in VS Code, you would use a simpler:
Trim filter (t)
This filter is applicable only when providing abbreviations for the Emmet: Wrap Individual Lines 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.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 the
{}
.CSS Emmet snippets
Values for CSS Emmet snippets should be a complete property name and value pair.
CSS custom snippets are applicable to all other stylesheet flavors like
scss
, less
or sass
. Therefore, don't include a trailing ;
at the end of the snippet value. Emmet will add it as needed based on whether the language requires it.Do not use Imindmap 11 full version crack mac & win.
:

is used to separate property name and value when Emmet tries to fuzzy match the abbreviation to one of the snippets.Note: After making changes to the
snippets.json
file, remember to reload VS Code for it to take effect.Tab stops and cursors in custom snippets
The syntax for tab stops in custom Emmet snippets follows the Textmate snippets syntax.
- Use
${1}
,${2}
for tab stops and${1:placeholder}
for tab stops with placeholders. - Previously,
|
or${cursor}
was used to denote the cursor location in the custom Emmet snippet. This is no longer supported. Use${1}
instead.
Emmet configuration
Below are Emmet settings that you can use to customize your Emmet experience in VS Code.
emmet.includeLanguages
Use this setting to add mapping between the language of your choice and one of the Emmet supported languages to enable Emmet in the former using the syntax of the latter. Make sure to use language ids for both sides of the mapping.For example:emmet.excludeLanguages
If there is a language where you do not want to see Emmet expansions, add it in this setting which takes an array of language id strings.emmet.syntaxProfiles
See Emmet Customization of output profile to learn how you can customize the output of your HTML abbreviations.For example:emmet.variables
Customize variables used by Emmet snippets.For example:emmet.showExpandedAbbreviation
Controls the Emmet suggestions that show up in the suggestion/completion list.Setting Value Description never
Never show Emmet abbreviations in the suggestion list for any language. inMarkupAndStylesheetFilesOnly
Show Emmet suggestions only for languages that are purely markup and stylesheet based ('html', 'pug', 'slim', 'haml', 'xml', 'xsl', 'css', 'scss', 'sass', 'less', 'stylus'). always
Show Emmet suggestions in all Emmet supported modes as well as the languages that have a mapping in the emmet.includeLanguages
setting.Note: In thealways
mode, the new Emmet implementation is not context aware. For example, if you are editing a JavaScript React file, you will get Emmet suggestions not only when writing markup but also while writing JavaScript.emmet.showAbbreviationSuggestions
Shows possible emmet abbreviations as suggestions. It istrue
by default.For example, when you typeli

Common questions
Custom tags do not get expanded in the suggestion list
Custom tags when used in an expression like
MyTag>YourTag
or MyTag.someclass
do show up in the suggestion list. But when these are used on their own like MyTag
, they do not appear in the suggestion list. This is designed so to avoid noise in the suggestion list as every word is a potential custom tag.Add the following setting to enable expanding of Emmet abbreviations using tab which will expand custom tags in all cases.
My HTML snippets ending with +
do not work?
HTML snippets ending with
+
like select+
and ul+
from the Emmet cheatsheet are not supported. This is a known issue in Emmet 2.0 Issue: emmetio/html-matcher#1. Workaround is to create your own custom Emmet snippets for such scenarios.Where can I set all the preferences as documented in Emmet preferences
You can set the preferences using the setting
emmet.preferences
. Only a subset of the preferences that are documented in Emmet preferences can be customized. Please read the preferences section under Emmet configuration.Any tips and tricks?
Of course!
- In CSS abbreviations, when you use
:
, the left part is used to fuzzy match with the CSS property name and the right part is used to match with CSS property value. Take full advantage of this by using abbreviations likepos:f
,trf:rx
,fw:b
, etc. - Use the new command Emmet: Wrap Individual Lines with Abbreviation instead of Emmet: Wrap with Abbreviation when you want each selected line to be wrapped by a repeater in the given abbreviation. For example, use
ul>li*
to wrap selected lines in an unordered list with each line as a list item. - Explore all other Emmet features as documented in Emmet Actions.
- Don't hesitate to create your own custom Emmet snippets.
Whether you are coding or writing the next vampire best-seller, you'relikely to need certain short fragments of text again and again. Usesnippets to save yourself tedious typing. Snippets are smart templatesthat will insert text for you and adapt it to their context.
Code Snippet Ios
To create a new snippet, select Tools | Developer | New Snippet..Sublime Text will present you with a skeleton for it.
Snippets can be stored under any package's folder, but to keep it simplewhile you're learning, you can save them to your
Packages/User
folder.# Snippets File Format
Snippets typically live in a Sublime Text package. They are simplifiedXML files with the extension
.sublime-snippet
. For instance, you couldhave a greeting.sublime-snippet
inside an Email package.The structure of a typical snippet is as follows (including the defaulthints Sublime Text inserts for your convenience):
The
snippet
element contains all the information Sublime Text needs inorder to know what to insert, whether to insert and when. Let'slook at each of these parts in turn.content
The actual snippet. Snippets can range from simple to fairly complextemplates. We'll look at examples of both later.
Keep the following in mind when writing your own snippets:
- If you want to get a literal
$
, you have to escape it likethis:$
. - When writing a snippet that contains indentation, always usetabs. When the snippet is inserted, the tabs will betransformed into spaces if the option

istrue
. - The
content
must be included in a<![CDATA[…]]>
section.Snippets won't work if you don't do this! - The
content
of your snippet must not contain]]>
becausethis string of characters will prematurely close the<![CDATA[…]]>
section, resulting in an XML error. To workaround this pitfall, you can insert an undefined variable intothe string like this:]]$NOT_DEFINED>
. This modified stringpasses through the XML parser without closing the contentelement's<![CDATA[…]]>
section, but Sublime Text willreplace$NOT_DEFINED
with an empty string before insertingthe snippet into your file. In other words,]]$NOT_DEFINED>
in your snippet filecontent
will be written as]]>
whenyou trigger the snippet.
tabTrigger
Defines the sequence of keys that must be pressed to insert this snippet.After typing this sequence, the snippet will kick in as soon as you hitthe ⭾ key.

# Environment Variables
Snippets have access to contextual information in the form ofenvironment variables. The values of the variables listed below are setautomatically by Sublime Text.
Variable | Description |
---|---|
$PARAM1 . $PARAMn | Arguments passed to the insert_snippet command. (Not covered here.) |
$SELECTION | The text that was selected when the snippet was triggered. |
$TM_CURRENT_LINE | Content of the cursor's line when the snippet was triggered. |
$TM_CURRENT_WORD | Word under the cursor when the snippet was triggered. |
$TM_DIRECTORY | Directory name of the file being edited. (since 3154) |
$TM_FILENAME | Name of the file being edited, including extension. |
$TM_FILEPATH | Path to the file being edited. |
$TM_FULLNAME | User's user name. |
$TM_LINE_INDEX | Column where the snippet is being inserted, 0 based. |
$TM_LINE_NUMBER | Row where the snippet is being inserted, 1 based. |
$TM_SELECTED_TEXT | An alias for $SELECTION. |
$TM_SCOPE | The scope of the beginning of each selected region. (since 3154) |
$TM_SOFT_TABS | YES if translate_tabs_to_spaces is true, otherwise NO . |
$TM_TAB_SIZE | Spaces per-tab (controlled by the tab_size option). |
Let's see a simple example of a snippet using variables:
# Fields
With the help of field markers, you can cycle through positions within thesnippet by pressing the ⭾ key. Fields are used to walk you through thecustomization of a snippet after it's been inserted.
In the example above, the cursor will jump to
$1
if you press ⭾once. If you press ⭾ a second time, it will advance to $2
, etc. Youcan also move backwards in the series with ⇧⭾. If you press⭾ after the highest tab stop, Sublime Text will place the cursor at theend of the snippet's content so that you can resume normal editing.If you want to control where the exit point should be, use the
$0
mark. Bydefault, this is the end of the snippet.You can break out of the field cycle any time by pressing Esc.
# Mirrored Fields
Identical field markers mirror each other: when you edit the first one, the restwill be populated in real time with the same value.
In this example, 'User name' will be filled out with the same value as 'FirstName'.
# Placeholders
By expanding the field syntax a little bit, you can define defaultvalues for a field. Placeholders are useful whenever there's a generalcase for your snippet, but you still want to keep it customizable.
Variables can be used as placeholders:
And you can nest placeholders within other placeholders too:
# Substitutions
In addition to the place holder syntax, tab stops can specify morecomplex operations with substitutions. Use substitutions to dynamicallygenerate text based on a mirrored tab stop. Of course, the tab stop youwant to use as variable has to be mirrored somewhere else in thesnippet.
The substitution syntax has the following syntaxes:
${var_name/regex/format_string/}
${var_name/regex/format_string/options}
The variable name:
1
, 2
… or an environment variable such as TM_FILENAME
or SELECTION
.Perl-style regular expression: See the Boost library documentation forregular expressions.
Snippet Tool Microsoft
See the Boost library documentation for format strings.
Optional. May be any of the following:
- i
- Case-insensitive regex.
- g
- Replace all occurrences of
regex
. - m
- Don't ignore newlines in the string.
With substitutions you can, for instance, underline text effortlessly:
Another more complex example can translate snail_case to Tile Case With Spaces.Basically, it combines two separate expressions and replaces into one.It also illustrates that replaces may occur before the actual tabstop.
You can also use environment variables with substitutions:
