Any Web page can include a form between <form>…</form> tags. In general, a form looks
like this in HTML:
<form method='post' action='url'>place form elements here</form>
where
points to the downstream CGI script that processes the
results from this form.url
Each occurrence of an <input>,
<select>, <textarea>, or other form element
causes the browser to display a widget for capturing data
entered on the form. These elements can be freely
intermixed with normal HTML tags such as bullet lists,
horizontal rules, and so forth.
