Visual Studio Code provides basic support for HTML programming out of the box. There is syntax highlighting, smart completions with IntelliSense, and customizable formatting. VS Code also includes great Emmet support. IntelliSenseAs you type in HTML, we offer suggestions via HTML IntelliSense. In the image below, you can see a suggested HTML element closure Document symbols are also available for HTML, allowing you to quickly navigate to DOM nodes by id and class name. You can also work with embedded CSS and JavaScript. However, note that script and style includes from other files are not followed, the language support only looks at the content of the HTML file. You can trigger suggestions at any time by pressing ⌃Space (Windows, Linux Ctrl+Space). You can also control which built-in code completion providers are active. Override these in your user or workspace settings if you prefer not to see the corresponding suggestions.

Auto update tagsWhen modifying a tag, the linked editing feature automatically updates the matching closing tag. The feature is optional and can be enabled by setting:
Color pickerThe VS Code color picker UI is now available in HTML style sections. It supports configuration of hue, saturation and opacity for the color that is picked up from the editor. It also provides the ability to trigger between different color modes by clicking on the color string at the top of the picker. The picker appears on a hover when you are over a color definition. HoverMove the mouse over HTML tags or embedded styles and JavaScript to get more information on the symbol under the cursor.

FoldingYou can fold regions of source code using the folding icons on the gutter between line numbers and line start. Folding regions are available for all HTML elements for multiline comments in the source code. Additionally you can use the following region markers to define a folding region: 0If you prefer to switch to indentation based folding for HTML use:
FormattingTo improve the formatting of your HTML source code, you can use the Format Document command ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I) to format the entire file or Format Selection ⌘K ⌘F (Windows, Linux Ctrl+K Ctrl+F) to just format the selected text. The HTML formatter is based on js-beautify. The formatting options offered by that library are surfaced in the VS Code settings:
The Marketplace has several alternative formatters to choose from. If you want to use a different formatter, define 7 in your settings to turn off the built-in formatter.Emmet snippetsVS Code supports Emmet snippet expansion. Emmet abbreviations are listed along with other suggestions and snippets in the editor auto-completion list.
If you'd like to use HTML Emmet abbreviations with other languages, you can associate one of the Emmet modes (such as 8, 9) with other languages with the 0 setting. The setting takes a and associates it with the language ID of an Emmet supported mode.For example, to use Emmet HTML abbreviations inside JavaScript:
We also support User Defined Snippets. HTML custom dataYou can extend VS Code's HTML support through a declarative custom data format. By setting 1 to a list of JSON files following the custom data format, you can enhance VS Code's understanding of new HTML tags, attributes and attribute values. VS Code will then offer language support such as completion & hover information for the provided tags, attributes and attribute values.You can read more about using custom data in the vscode-custom-data repository.

Go to the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)) and type 'html' to see a list of relevant extensions to help with creating and editing HTML.
