You can also look up documentation for Style Sheets, create and move rulesets, introduce variables, and more.
Before you start
Make sure the CSS bundled plugin is enabled on the Settings/Preferences | Plugins page, see Managing plugins for details.
GoLand provides code completion for properties, their values, selectors, variables, and mixins.
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.
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.
Open the HTML file with a CDN link to an external CSS library. GoLand highlights the link.
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
Complete Sass and SCSS selectors
Search and navigation
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.
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.
View documentation for a property
Position the caret at the property and press Ctrl+Q or selectfrom 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 , and clear the Show quick documentation on mouse move checkbox.
To have the Documentation popup shown faster or slower, open the Settings/Preferences dialog Ctrl+Alt+S, go to , 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 selectfrom 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.
In the editor, position the caret at the expression to convert into a variable and press Ctrl+Alt+V or selectfrom the context menu or from the main menu.
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.
For .scss, and .sass, select the global or local scope for the variable.
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.
Select the declarations to introduce. If you need only one declaration, just position the caret inside it.
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
Position the caret anywhere in the ruleset to move and press F6.
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.
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.
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.
Turn on compatibility check
In the Settings/Preferences dialog Ctrl+Alt+S, go to .
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.
