Hi, I am doing the tutorial to build a ShoppingList full stack app, and I was wondering how to add a class/id attribute for HTML on App.kt.
For example, h1 {+"Full-Stack Shopping List"} -> I want to write something like this: h1(classes="hello"){+"Full-Stack Shopping List"}
I realized that for id, I can simply write: h1 {id = "hello" +"Full-Stack Shopping List"} .
I have researched and it seems like using kotlinx.html (https://github.com/Kotlin/kotlinx.html) might be the solution. However, h1("hello"){+"Full-Stack Shopping List"} doesn't work.
Does anyone know how to add a class attribute specifically in the App.kt on the tutorial. (https://kotlinlang.org/docs/multiplatform-full-stack-app.html#build-the-user-interface)?

I'm not sure what you're searching for, but the tutorial you linked uses Kotlin React (https://github.com/JetBrains/kotlin-wrappers/tree/master/kotlin-react-dom) and not KotlinX.html

I want to write something like this: <div class="hello"> in kotlin. Is there a way to add a class attribute? I realize that <div id="hello"> is equivalent to div {id = "hello"} .

It depends on the wrapper. If I recall correctly, Kotlin React uses classes = "stuff". Compose Web uses classes("stuff").

Check which one you're using, then maybe ask again in #kotlinx-html, #react or #compose-web for specifics

I see. Thank you for the help!
