# HTML
HTML support is available through the [HTML extension](https://github.com/zed-industries/zed/tree/main/extensions/html).
- Tree-sitter: [tree-sitter/tree-sitter-html](https://github.com/tree-sitter/tree-sitter-html)
- Language Server: [microsoft/vscode-html-languageservice](https://github.com/microsoft/vscode-html-languageservice)
This extension is automatically installed, but if you do not want to use it, you can add the following to your settings:
```json [settings]
{
"auto_install_extensions": {
"html": false
}
}
```
## Formatting
By default Zed uses [Prettier](https://prettier.io/) for formatting HTML.
You can disable `format_on_save` by adding the following to your Zed `settings.json`:
```json [settings]
"languages": {
"HTML": {
"format_on_save": "off",
}
}
```
You can still trigger formatting manually with {#kb editor::Format} or by opening [the Command Palette](..//getting-started.md#command-palette) ({#kb command_palette::Toggle}) 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:
```json [settings]
"languages": {
"HTML": {
"formatter": "language_server",
}
}
```
You can customize various [formatting options](https://code.visualstudio.com/docs/languages/html#_formatting) for `vscode-html-language-server` via your Zed `settings.json`:
```json [settings]
"lsp": {
"vscode-html-language-server": {
"settings": {
"html": {
"format": {
// Indent under and (default: false)
"indentInnerHtml": true,
// Disable formatting inside
