A simple example for `use_mutation_observer`.
|
||||
|
||||
If you don't have it installed already, install [Trunk](https://trunkrs.dev/) and [Tailwind](https://tailwindcss.com/docs/installation)
|
||||
as well as the nightly toolchain for Rust and the wasm32-unknown-unknown target:
|
||||
|
||||
```bash
|
||||
cargo install trunk
|
||||
npm install -D tailwindcss @tailwindcss/forms
|
||||
rustup toolchain install nightly
|
||||
rustup target add wasm32-unknown-unknown
|
||||
```
|
||||
|
||||
Then, open two terminals. In the first one, run:
|
||||
|
||||
```
|
||||
npx tailwindcss -i ./input.css -o ./style/output.css --watch
|
||||
```
|
||||
|
||||
In the second one, run:
|
||||
|
||||
```bash
|
||||
trunk serve --open
|
||||
```
