The core building block used to build up HTML. Here we create an Html value with no attributes and one child:

hello : Html msg
hello =
  div [] [ text "Hello!" ]

Set attributes on your Html. Learn more in the Html.Attributes module.

Just put plain text in the DOM. It will escape the string so that it appears exactly as you specify.

text "Hello World!"

General way to create HTML nodes. It is used to define all of the helper functions in this library.

div : List (Attribute msg) -> List (Html msg) -> Html msg
div attributes children =
    node "div" attributes children

You can use this to create custom nodes if you need to create something that is not covered by the helper functions in this library.

Transform the messages produced by some Html. In the following example, we have viewButton that produces () messages, and we transform those values into Msg values in view.

type Msg = Left | Right


view : model -> Html Msg
view model =
  div []
    [ map (\_ -> Left) (viewButton "Left")
    , map (\_ -> Right) (viewButton "Right")
    ]


viewButton : String -> Html ()
viewButton name =
  button [ onClick () ] [ text name ]
