Usage

• Input the HTML content for verification into the field labeled as Html - required
• Specify if empty string needs to be rejected using the field labeled as Reject empty string in the Additional Fields collection - optional, default: false
• Specify if at least one tag needs to be present in order to the validator to accept the input using the field labeled as Require At Least One Tag in the Additional Fields collection - optional, default: false
• Specify custom rules using the Custom Rules field in the 'Additional Fields' collection - optional, default:

{
	"extends": [
		"html-validate:recommended"
	],
	"rules": {
		"close-order": "error",
		"void-style": "off"
	}
}

For example to allow self-closing tags, you can set Custom Rules to:

{
  "extends": [
    "html-validate:recommended"
  ],

  "rules": {
    "close-order": "error",
    "no-self-closing": "off",
    "void-style": "off"
  }
}

Note: The Custom Rules field needs to be a valid JSON if set.
