Custom HTML Element Name Validator
The Custom HTML Element Name Validator is a utility that checks whether a proposed HTML tag name is valid for creating custom elements according to the Web Components specification. Custom element names must include a hyphen, avoid reserved names, and follow specific naming rules to ensure compatibility across browsers.
Unquoted Attribute Value Validator
The HTML/CSS/JS Unquoted Attribute Value Validator is a utility that analyzes attribute values in markup and code to determine whether they can be safely written without quotation marks. In HTML and related contexts, certain attribute values may be left unquoted if they do not contain spaces or restricted characters, but doing so incorrectly can break parsing or introduce subtle bugs.
