accessible_form_validation

Improves accessibility by converting native browser form validation messages into inline messages compatible with screen readers and theming.

Features

This module replaces browser-native form validation popups with inline error messages, making forms more accessible—especially for screen reader users.
Key features include:

• Converts HTML5 browser validation messages into inline, themeable messages.
• Allows enabling separately for the default theme and the admin theme.
• Lets you customize the CSS class used for the error message container (default theme only).

Post-Installation

After installation:

• Navigate to the module’s configuration page at Configuration » User Interface » Accessible form validation.
• Choose whether to enable the feature for the default theme, the admin theme, or both.
• Optionally, define a custom CSS class for the error message container in the default theme.

No additional setup is required unless your theme needs specific styling for error messages.

Additional Requirements

This module has no dependencies beyond Drupal core.
