HTML5 form validation error messages are hard-coded to the browser. Civem.js lets you easily change them to whatever you wish. For translation or consistency with your server-side error messages. Civem.js does not depend on any library or framework, so you can use it without a doubt.

1. Grab the latest download
2. Add the civem.js script to your page
3. Start using the custom error message attributes on your input, textarea and select elements

Any input, textarea or select element may contain:
