 8## Syntax Highlighting Code Blocks
 9
10Zed supports language-specific syntax highlighting of markdown code blocks by leveraging [tree-sitter language grammars](../extensions/languages.md#grammar). All [Zed supported languages](../languages.md), including those provided by official or community extensions, are available for use in markdown code blocks. All you need to do is provide a language name after the opening <kbd>```</kbd> code fence like so:
11
12````python
13```python
14import functools as ft
15
16@ft.lru_cache(maxsize=500)
17def fib(n):
18    return n if n < 2 else fib(n - 1) + fib(n - 2)
19```
20````

22## Configuration
23
24### Format
25
26Zed supports using Prettier to automatically re-format Markdown documents. You can trigger this manually via the {#action editor::Format} action or via the {#kb editor::Format} keyboard shortcut. Alternately, you can automatically format by enabling [`format_on_save`](../configuring-zed.md#format-on-save) in your settings.json:
27
28```json [settings]
29  "languages": {
30    "Markdown": {
31      "format_on_save": "on"
32    }
33  },
34```
35
36### Trailing Whitespace
37
38By default Zed will remove trailing whitespace on save. If you rely on invisible trailing whitespace being converted to `<br />` in Markdown files you can disable this behavior with:
39
40```json [settings]
41  "languages": {
42    "Markdown": {
43      "remove_trailing_whitespace_on_save": false
44    }
45  },
46```
