        .padding(SpacingValue::Integer(4))
        .background_color(Color::new(ColorPalette::Blue, ColorShade::Shade500))
        .text_color(Color::new(ColorPalette::White, ColorShade::Shade500))
        .rounded_lg()
        .hover(|b| b.background_color(Color::new(ColorPalette::Blue, ColorShade::Shade600)))
        .build();

    view! { <button class=classes.to_string()>"Click me"</button> }

            {"Click me"}
        </button>
    }
}

WASM Example

use tailwind_rs_wasm::*;

// All crates are now WASM-compatible!

    .background_color(Color::new(ColorPalette::Blue, ColorShade::Shade500))
    .text_color(Color::new(ColorPalette::White, ColorShade::Shade500))
    .build();

// Works in any browser environment
let css_classes = classes.to_string();
