  • Adds the Image is decorative option to the Accessibility Checker error dialog for images without alternative text or the role="presentation" attribute.

Important: When a11y_advanced_options is set to true, a11ychecker_allow_decorative_images will default to true.

<iframe title="Rich Text Area. Press ALT-0 for help."></iframe>

The title attribute is read by screen-readers to help users identify the editor. This option only applies to TinyMCE classic (iframe) mode and has no effect on inline editors.

Type: String

Default Value: 'Rich Text Area. Press ALT-0 for help.'

Example: Using iframe_aria_text

  selector: 'textarea',  // change this value according to your html
  iframe_aria_text: 'Text Editor'
