Themes and Swatches

In addition to providing WAI-ARIA and keyboard support, Kendo UI for jQuery ships with a contrast-compliant theme that can be used to serve users with low vision or other visual disabilities, which require a high contrast ratio between the foreground and background elements.

Ocean Blue A11y Accessibility Swatch

The 1.4.3 Contrast (Minimum) and 1.4.6 Contrast (Enhanced) Web Content Accessibility Guidelines sections define the required contrast ratio for compliance.

WCAG Level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. WCAG Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text.

The Kendo UI for Angular library conforms to WCAG Level AA with the Default Ocean Blue A11y theme swatch coming with enabled contrast focus indicators, available as of version 6.0.1 of the Default Theme.


Kendo UI for jQuery distributes the Default Ocean Blue A11y theme swatch with the @progress/kendo-theme-default package. If you don't need to apply any customization to the theme, reference the precompiled CSS directly from CDN:

    <!--This is an example link and 6.2.0 represents the version of the theme.
    It is recommended to use the latest version.-->

To customize the provided accessibility swatch, install the Default theme and import the swatch styles directly:

// Import the Default theme accessibility swatch
import '@progress/kendo-theme-default/dist/default-ocean-blue-a11y.scss';
