HTML

HTML support is available through the HTML extension.

This extension is automatically installed, but if you do not want to use it, you can add the following to your settings:

{
  "auto_install_extensions": {
    "html": false
  }
}

Formatting

By default Zed uses Prettier for formatting HTML.

You can disable format_on_save by adding the following to your Zed settings.json:

  "languages": {
    "HTML": {
      "format_on_save": "off",
    }
  }

You can still trigger formatting manually with cmd-shift-i|ctrl-shift-i or by opening the Command Palette (cmd-shift-p|ctrl-shift-p) and selecting "Format Document".

LSP Formatting

To use the vscode-html-language-server language server auto-formatting instead of Prettier, add the following to your Zed settings:

  "languages": {
    "HTML": {
      "formatter": "language_server",
    }
  }

You can customize various formatting options for vscode-html-language-server via your Zed settings.json:

  "lsp": {
    "vscode-html-language-server": {
      "settings": {
        "html": {
          "format": {
            // Indent under <html> and <head> (default: false)
            "indentInnerHtml": true,
            // Disable formatting inside <svg> or <script>
            "contentUnformatted": "svg,script",
            // Add an extra newline before <div> and <p>
            "extraLiners": "div,p"
          }
        }
      }
    }
  }

Using the Tailwind CSS Language Server with HTML

To get all the features (autocomplete, linting, etc.) from the Tailwind CSS language server in HTML files, you need to configure the language server so that it knows about where to look for CSS classes by adding the following to your settings.json:

{
  "lsp": {
    "tailwindcss-language-server": {
      "settings": {
        "experimental": {
          "classRegex": ["class=\"([^\"]*)\""]
        }
      }
    }
  }
}

With these settings, you will get completions for Tailwind CSS classes in HTML class attributes. Examples:

<div class="flex items-center <completion here>">
  <p class="text-lg font-bold <completion here>">Hello World</p>
</div>
