## Code Blocks

Code blocks.. ❤️ with automatic syntax highlighting ✨‍

See [the docs](https://www.getzola.org/documentation/content/syntax-highlighting/) for options.

### Inline Code block

If we want, we can also `specify inline code` which is useful for `the small stuff`.

### Rust

```rust
fn main() {
    let greetings = ["Hello", "Hola", "Bonjour",
                     "Ciao", "こんにちは", "안녕하세요",
                     "Cześć", "Olá", "Здравствуйте",
                     "Chào bạn", "您好", "Hallo",
                     "Hej", "Ahoj", "سلام",
                     "Hej", "Hallo", "Hei",
                     "Helló", "Hallo", "Buna ziua",
                     "Merhaba"];

    for (num, greeting) in greetings.iter().enumerate() {
        print!("{} : ", greeting);
