An HTML form is a section of the document that collects user input. The user input is most often sent to a server for processing¹. An HTML form is created using the <form> element, which is a container for different types of input elements, such as text fields, checkboxes, radio buttons, submit buttons, etc¹.

The <form> element has some attributes that control how the form data is submitted and validated. Some of the common attributes are:

• action: Specifies the URL of the server-side script that handles the form data¹.

• method: Specifies the HTTP method to use when sending the form data. The possible values are get and post¹.

• enctype: Specifies how the form data is encoded when sending it to the server. The possible values are application/x-www-form-urlencoded (the default), multipart/form-data (for file uploads), and text/plain (for debugging)¹.

• name: Specifies a name for the form, which can be used to identify it in scripts².

• target: Specifies where to display the response after submitting the form. The possible values are _self (the default), _blank, _parent, _top, or a name of an existing window or frame².

• novalidate: Specifies that the form should not be validated before submitting it².

Here is an example of an HTML form code that collects some basic information from the user and sends it to a server-side script using the post method³:

This is how the HTML code above will be displayed in a browser:
