Syntax highlighting in markdown in the generated website via Hugo ( https://github.com/llvm/mlir-www/blob/main/.github/workflows/main.yml ) and GitHub have syntax highlighting support for code blocks in markdown. But for that, there is an identifier that's used to determine which highlighting to use (there is auto detection too but doubt MLIR detection is great). So

```mlir
func.func @foo(%arg0: i32){
  // Do something
}
```

looks different from

```mlir_example
func.func @foo(%arg0: i32){
  // Do something
}
```

as the latter is not considered a block of MLIR and treated as unknown format. So ideally the method to delineate MLIR examples is such that we don't lose syntax highlighting across either - I believe that's doable and just needs testing to verify.
