GoLand 2021.2 Help

Style Sheets

With GoLand, you can write style definitions in CSS as well as in various languages that compile into it, such as Sass, Less, SCSS, or Stylus.

You can also look up documentation for Style Sheets, create and move rulesets, introduce variables, and more.

Before you start

Make sure the CSS plugin is enabled on the Settings/Preferences | Plugins page, tab Installed, see Managing plugins for details.

Code completion

GoLand provides code completion for properties, their values, selectors, variables, and mixins.

Style Sheets: basic code completion

Complete Style Sheet classes

Completion for CSS, SCSS, Less, and Sass classes and ids is available in HTML files, in various types of templates (for example, in Angular or Vue.js), as well as in JSX code.

In HTML files, GoLand first suggests classes and ids from the style tag and files linked with link tags. If no matching results are found, GoLand also suggests symbols defined in all stylesheet files in the project. To see all classes and ids defined in the project straight away, before you start typing, press Ctrl+Space twice.

Project-wide completion for Style Sheet symbols in HTML

Complete Style Sheet classes from external libraries

With GoLand, you can also get completion for class names from Twitter Bootstrap or other CSS libraries that are linked from a CDN in an HTML file without adding these libraries to your project dependencies.

Enabling completion for an external CSS library
  1. Open the HTML file with a CDN link to an external CSS library. GoLand highlights the link.

  2. To enable completion for the library, press Alt+Enter on the link and select Download library from the list. Alternatively, hover the mouse over the link and click Download library.

Complete Sass and SCSS selectors

GoLand also provides completion for Sass and SCSS selectors - including nested selectors and selectors created with an ampersand (&).

Search and navigation

Navigation for SCSS selectors
  • To find usages of a Style Sheet symbol, place the caret at it and press Alt+F7. Learn more from Search for usages in a project.

  • To jump from a usage of a Style Sheet symbol to its definition, press Ctrl+B. Navigation to definition is available for classes, ids, selectors - including nested selectors and selectors with an ampersand &- as well as for variables and mixins.

    Learn more from Go to declaration.

Documentation look-up

For properties and pseudo-elements, GoLand can show you a summary from the corresponding MDN article. This summary is displayed in the Documentation popup which shows a brief description of the property and its values, as well as information about its compatibility with various browsers.

Style sheets quick documentation: compatible browsers are listed

If the property is available in all versions of browsers, GoLand does not show any information about its compatibility.

Otherwise, the Documentation popup also lists the browsers and their versions that support the property.

For selectors, GoLand also shows their specificity.

Documentation look-up: specificity fpr selectors

View documentation for a property

  • Position the caret at the property and press Ctrl+Q or select View | Quick Documentation Lookup from the main menu.

  • When you hover the mouse pointer over a property, GoLand immediately displays the reference for it in the Documentation popup.

    You can turn off this behavior or configure the popup to appear faster or slower, see Configuring the behavior of Documentation popup below.

Configure the behavior of Documentation popup

  • To turn off showing documentation automatically, open the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Editing, and clear the Show quick documentation on hover checkbox.

  • To have the Documentation popup shown faster or slower, open the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Code Completion, then select the Show the documentation popup checkbox and specify the delay time.

Open the MDN documentation in the browser

  • In the Documentation popup Ctrl+Q, click the link at the bottom.

  • Press Shift+F1 or select View | External Documentation from the main menu.


With GoLand, you can convert expressions in Style Sheets into variables and introduce these variables using the var(--var-name) syntax in .css files or the $ syntax in .scss and .sass files.

Style sheets: introducing a variable

Introduce variables

  1. In the editor, position the caret at the expression to convert into a variable and press Ctrl+Alt+V or select Refactor | Introduce | Introduce Variable from the context menu or from the main menu.

  2. If more than one occurrence of the selected expression is found, select Replace this occurrence only or Replace all occurrences from the Multiple occurrences found list.

  3. For .scss, and .sass, select the global or local scope for the variable.

  4. In the field with red borders, accept the suggested variable name or specify a custom name. Press Enter when ready.

With GoLand, you can create new rulesets from existing declarations in CSS, SCSS, Sass, or Less files and even move entire rulesets between files using refactoring and intention actions.

Introduce rulesets

  1. Select the declarations to introduce. If you need only one declaration, just position the caret inside it.

  2. Press Alt+Enter and select Introduce ruleset from the list.

GoLand creates a new ruleset with the same selector and moves the selected declarations to it. If the selection contains comments, nested selectors, and so on, they are also moved to the new ruleset.

Move rulesets to other files

  1. Position the caret anywhere in the ruleset to move and press F6.

  2. In the dialog that opens, specify the file to move the ruleset to. If the specified file does not exist, GoLand will suggest creating it.

  3. By default, GoLand automatically opens the file where the ruleset is moved. To change this behavior, clear the Open in editor checkbox.

Common refactorings, such as Copy, Move, or Rename, are also available.

Rename refactoring

Checking compatibility with browsers

Besides looking up in the documentation popup, you can check Style Sheet properties for compatibility with specific browsers on the fly. This inspection is based on the MDN Browser Compatibility Data and shows you a warning every time a property is not supported in one of the targeted browsers.

Style sheet compatibility inspection popup

Turn on compatibility check

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Inspections.

  2. Expand the CSS node and select the Browser compatibility for properties. In the Options area, select the browsers you want to target and the minimum versions for them.

Changing color values

With GoLand, you can easily change color values in Style Sheets without typing hexadecimal codes.

Editing color values in Style Sheets

Choose colors

  1. Open the desired Style Sheet for editing.

  2. Type color:, and then press Ctrl+Space.

  3. In the Choose color dialog that opens, pick the desired new color and click Choose.

Preview the code of colors

  • GoLand marks each color property with a gutter icon of the corresponding color. When you hover over a color icon, GoLand displays a popup that shows the color preview and its hexadecimal code.

    To use a code instead of a human-readable color name, press Alt+Enter and select Convert color to <color code system> from the list, where <color code system> is HEX, HSL, HWB, or RGB

Show color icons in the gutter

By default, GoLand displays color icons in the gutter. If they are for some reason hidden, you can return them at any time.

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Gutter Icons. The Gutter Icons page opens.

  2. In the Common area, select the Color preview checkbox.

Viewing the styles applied to a tag

In HTML and XHTML files, GoLand can show you all the styles applied to an arbitrary tag.

Viewing the styles applied to the tag <body>
  • From the context menu of a tag, select Show Applied Styles for Tag.

    GoLand opens the CSS Styles tool window with two panes, the left-hand pane shows the styles for the tag and the right-hand pane shows their definitions. For each tag, GoLand opens a separate tab.

    From the tool window, you can navigate to tags and definitions of properties in your source code.

    • To jump to the tag, click the Navigate to Tag toolbar button on the toolbar of the left-hand pane.

    • To jump to the definition of a property, select it in the left-hand pane and click the Navigate to Style Sources button on the toolbar of the right-hand pane.
