Application Form

An HTML form for user input.

As a data collection form

The form element is a container for different types of input elements, such as: text fields, checkboxes, radio buttons, submit buttons, etc, which allow for the efficient collection and processing of user data. It is a fundamental component of web development, enabling user engagement and data exchange.

Attributes for the form element:
The action attribute defines the action to be performed when the form is submitted. Usually, the form data is sent to a file on the server when the user clicks on the submit button. If the action attribute is omitted, the action is set to the current page.
The method attribute specifies the HTTP method to be used when submitting the form data. The form-data can be sent as URL variables (with method="get") or as HTTP post transaction (with method="post"). The default HTTP method when submitting form data is GET.
The target attribute specifies where to display the response that is received after submitting the form. The default value is _self which means that the response will open in the current window.

Important specifications to consider:
The label tag defines a label for many form elements. It is useful for screen-reader users, because the screen-reader will read out loud the label when the user focuses on the input element. Associating labels with all input fields also benefits SEO. With proper labels, search engines will understand the page content better, leading to a positive impact on the page search rankings.
Each input field must have a name attribute to be submitted. If the name attribute is omitted, the value of the input field will not be sent at all. For the form element, the name attribute is used to reference elements in a JavaScript, or to reference form data after a form is submitted. And, it must be unique among the forms in a document and not an empty string in HTML5.
The difference between using the input or button elements to submit the form is that the input elements are void elements, which means they can not have child nodes, such as text, and can only have a start tag. On the other hand, the button element offers more flexibility because you can nest text, images, and icons inside it.
By default, form controls are associated with their nearest ancestor form element, while form controls that are not nested within a form are not associated with any form. The form attribute enables overriding these default behaviors. The form attribute specifies the form the button belongs to. The value of this attribute must be equal to the id attribute of a form element in the same document. Including the form attribute does not mean the element will be submitted with the form. Only submittable elements, including button, input, select, and textarea, have their name and values submitted when their associated form is submitted.

As a general container

The form element in HTML, beyond its traditional use for data collection forms, acts as a general container for interactive elements within a document. In addition, it is considered a semantic label for grouping related content.

The textarea element can be used without forms to display multiline, editable text on a website. While traditionally part of forms, it can also be used for purposes such as code editing, displaying notes, creating chat text boxes, etc. You can see these kinds of uses through the small screen.

It does not matter how slowly you go as long as you do not stop.
