Exploring HTML Forms: Elements, Input Fields, and Form Controls

HTML forms are an essential component of modern web development. They allow website visitors to submit information, such as user names, passwords, or search queries, to a server for processing.

HTML forms are created using the <form> tag, which contains various input elements such as text boxes, drop-down menus, checkboxes, and radio buttons.

As an example:

Editor

Loading...

In this example:

  • The method attribute is set to "POST", which means that the form data will be sent to the server using the HTTP POST method.
  • The action attribute is set to "/submit-form", which specifies the URL of the server-side script that will process the submitted data.
  • The form contains two input fields, one for the name and one for the email address. The label elements are used to associate the input fields with their respective labels.
  • The name attributes for the input fields are set to "name" and "email", respectively. These names are used to identify the input data when it is submitted to the server.
  • The type attribute for the email input field is set to "email", which ensures that the user enters a valid email address.
  • The form also contains a submit button, which the user can click to submit the form data to the server. The value attribute of the button is set to "Submit", which specifies the text that will be displayed on the button.

The <input> Element​

The <input> element is one of the most commonly used form elements in HTML. It creates an interactive control in a form, such as a text box, a radio button, a checkbox, a button, or a file upload field. The type of control is determined by the type attribute of the <input> element.

The text Input Type​

The type="text" attribute is used to create a text box where the user can enter text.

The name and id attributes are used to identify the input field.

The type="checkbox" attribute is used to create a checkbox that the user can check or uncheck.

The name and id attributes are used to identify the checkbox.

As an example:

Editor

  • The name and id attributes are used to identify the checkbox. - The <label> element is used to provide a textual label for the checkbox.

The radio Input Type​

The type="radio" attribute is used to create a radio button that the user can select.

The name and id attributes are used to identify the radio button.

As an example:

Editor

Loading...

In this example:

  • This creates two radio buttons that the user can select.
  • The name attribute is used to group the radio buttons together. The value attribute specifies the value that will be submitted to the server when the form is submitted.
  • The <label> elements are used to provide a textual label for each radio button.

The submit Input Type​

The name and id attributes are used to identify the file upload field.

As an example:

Editor

Text Fields​

Text fields are one of the most common types of form elements in HTML. They allow users to enter text input into a form. The <input> element is used to create a text field in HTML.

The <label> Element​

As an example:

Editor

In this example:

  • The <label> element contains an <img> element and some text.
  • When the user clicks on the label, the corresponding input field will be focused, and the <img> and text will be highlighted together.
  • This provides a more visually appealing and informative label for the input field.

Name Attribute for <input>​

The name attribute is an important attribute for the <input> element, as it is used to identify the form data when the form is submitted to the server. When the form is submitted, the name attribute is used as the key for the value that is sent to the server.

As an example:
