Question

Is it possible to nest html forms like this

so

Answer 1

The second form will be ignored, see the snippet from WebKit for example:

bool HTMLParser::formCreateErrorCheck(Token* t, RefPtr& result)
{
    // Only create a new form if we're not already inside one.
    // This is consistent with other browsers' behavior.
    if (!m_currentFormElement) {
        m_currentFormElement = new HTMLFormElement(formTag, m_document);
        result = m_currentFormElement;
        pCloserCreateErrorCheck(t, result);
    }
    return false;
}
