skeleton

Loading placeholder primitive

Use class="skeleton" on a block element and control its size with normal CSS.

<div
  style="height: 2.5rem; width: 2.5rem; border-radius: 9999px;"
  class="skeleton"
></div>

Installation

Load the AngularCSS stylesheet. This entry needs no AngularCSS JavaScript or angular.css module dependency. Add AngularTS when using application bindings such as ng-model or ng-click. See Installation for the complete setup.

This entry uses native HTML and CSS. AngularCSS registers no runtime directive for it. Authored loading placeholder.

Anatomy

Root styling selector

  • .skeleton

Semantic structure

Use semantic HTML with the root styling selector above. Native elements provide the structure; the stylesheet supplies presentation.

API

Attributes and state

This component has no directive-specific attributes beyond its semantic HTML.

Attributes remain authored HTML, native state, or AngularTS inputs. AngularCSS does not write element state.

CSS custom properties

This styling hook does not define component-specific CSS custom properties.

DOM events

This component does not emit a component-specific custom event.

Native DOM events continue to work normally. AngularTS event directives such as ng-click and ng-keydown, plus the data-change model callback, remain application-owned.

Behavior

Authored loading placeholder. AngularCSS supplies styling without a runtime directive. Native HTML owns platform behavior; AngularTS owns application values, commands, and authored state.

AngularCSS does not replace AngularTS interpolation, bindings, structural directives, form controllers, validation, or application state.

Accessibility

Use the appropriate live-region or status semantics for dynamic feedback. Decorative feedback must stay hidden from assistive technology.

Authored accessible names and relationships are preserved. Test the final composition with keyboard navigation and assistive technology because labels and content come from the application.

Customization

Target semantic elements, native state selectors, and component classes with ordinary CSS. Behavior and accessible state remain with native HTML and AngularTS; visual choices belong in the application stylesheet.
