# Blazor PDFViewer Accessibility | ||
|
||
@[template](/_contentTemplates/common/parameters-table-styles.md#table-layout) | ||
|
||
|
||
|
||
Out of the box, the Telerik UI for Blazor PDFViewer provides extensive accessibility support and enables users with disabilities to acquire complete control over its features. | ||
|
||
|
||
The PDFViewer is compliant with the [Web Content Accessibility Guidelines (WCAG) 2.2 AA](https://www.w3.org/TR/WCAG22/) standards](https://www.w3.org/TR/WCAG22/) and [Section 508](http://www.section508.gov/) requirements, follows the [Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA)](https://www.w3.org/WAI/ARIA/apg/) best practices for implementing the [keyboard navigation](#keyboard-navigation) for its `component` role, provides options for managing its focus and is tested against the most popular screen readers. | ||
|
||
## WAI-ARIA | ||
|
||
|
||
This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any. | ||
|
||
|
||
The PDFViewer component contains two inner elements - a toolbar and a page container. | ||
|
||
[ToolBar accessibility specification]({{toolbar_a11y_link}}) | ||
|
||
| Selector | Attribute | Usage | | ||
| -------- | --------- | ----- | | ||
| `.k-pdfviewer .k-canvas` | `tabindex=0` | Defines the focusable page container element. | | ||
| | `aria-label` | Describes the purpose of the focusable container. Translatable message. | | ||
| | `role=document` | Defines that content should be evaluated in reader mode by assistive technologies. | | ||
| `.k-pdfviewer .k-toolbar .k-button:has(.k-svg-i-search, .k-i-search)` | `aria-haspopup=dialog` | Describes that the Search tool button opens a dialog element. | | ||
| `.k-pdfviewer .k-canvas .k-search-panel` | `role=dialog` | Describes the role of the Search panel. | | ||
| | `aria-label` | Translatable message, same label as the one, used to describe the Toolbar Search tool. | | ||
|
||
## Section 508 | ||
|
||
|
||
The PDFViewer is fully compliant with the [Section 508 requirements](http://www.section508.gov/). | ||
|
||
## Testing | ||
|
||
|
||
The PDFViewer has been extensively tested automatically with [axe-core](https://github.com/dequelabs/axe-core) and manually with the most popular screen readers. | ||
|
