Label
Give a form control a clear label and required marker.

use blinc_cn as cn;
use blinc_layout::prelude::*;
pub fn label_demo() -> Div {
div()
.class("demo-stack")
.child(cn::label("Email address").required())
.child(text("Labels give a control its context.").class("demo-caption"))
}
@layer components {
.cn-label {
font-family: var(--font-sans);
}
.cn-label {
color: var(--cn-label-color, var(--text-primary));
}
.cn-label-text {
color: var(--cn-label-color, var(--text-primary));
}
.cn-label:disabled > .cn-label-text {
color: var(--text-tertiary);
}
.cn-label-required {
color: var(--error);
}
}
Usage and properties
Give a form control a clear label and required marker. Apply CSS after the component layer to restyle the documented parts.
Use the installation guide to add blinc_cn and its component stylesheet. Create the fixture bindings once, and return the demo from your UI builder. Values marked Bound accept Signal/Computed sources where the API supports them; structural options configure the component at construction.
| Property | Type | Update model | This example |
|---|---|---|---|
content | string | Construction | Email address |
required | builder flag | Construction | enabled |
Keyboard and interaction
Informational content; no activation or Tab stop is required.
Customizing it
Add application CSS after the default component layer. These selectors are the restyling surface for this component:
.cn-label.cn-label-text.cn-label-required
Theme and component variables: --primary, --text-primary, --text-secondary, --surface, --border, --radius-default, --duration-fast, --ease-state.
Built-in themes
The Live theme control installs Blinc's own theme bundles, including their colours, focus rings, corner shapes and motion tokens.
pub fn theme_bundle_for(name: &str) -> blinc_theme::ThemeBundle {
match name {
"restrained" => blinc_theme::RestrainedTheme::bundle(),
"expressive" => blinc_theme::ExpressiveTheme::bundle(),
_ => blinc_theme::HybridTheme::bundle(),
}
.with_css(blinc_cn::cn_styles::CN_STYLES)
}Download the default widget and component stylesheets. Sample assets and licenses are available in the asset guide.
Documentation
From the canonical component guide.
Inputs, selects and checkboxes take a .label(..) of their own. A standalone
label's text is a string, a Signal<String> or a Computed<String>, and
follows a signal in place:
cn::label("Email").required() // marks the field required
cn::label("Notes").size(LabelSize::Small)
cn::label(status) // a Signal<String>
Platforms and version
The component API is available in Blinc 0.6.0. The Live example runs in a dedicated worker and requires a compatible GPU surface. Preview and Code remain available when Live cannot start. The canvas has a descriptive label; a full screen-reader DOM mirror is not provided. The gallery integration is based on revision e2e55c24e078.
Recordings and live demos use the default Hybrid theme with bundled Noto Sans. The recording uses a 560 × 320 logical viewport at twice that resolution. Live follows its container and actual display density. Source base revision · Exact build source · Artifact versions and checksums · Font license.
