Form is the most common UI component that developers need in any kind of application. In this blog, we will talk about developing a form component in HTML. HTML provides a self-implemented <Form> tag that serves perfectly to display a form.
<form>

Code language: HTML, XML (xml)
Above code is how we need initialize the <Form> tag.
Elements of <form> tag
Input Element
It takes an input and runs a particular function on submitting the form. To take the input, we use the <input> element.
We can customize the type of input of each field in the form by using the type attribute provided along with the input Element. Some of the commonly used input type attributes supported by the <Form> tag are:
- <input type=”text”>: It is used to take input in a single-line text. This is also the default value of the type attribute.
- <input type=”radio”>: It is used when we want the user to select from the given choices. This type displays the radio button.
- <input type=”checkbox”>: It is also used to check from the given options. It displays a checkbox.
- <input type=”submit”>: This attribute is used to submit the form.

Here’s a code snippet on using the form:
In the above snippet, you would have noticed the <label> tag.
Label Element
Label Element is used to give a label to each form field. This is useful for screen-read users. It also facilitates clicking within the <label> tag region which helps users who find it difficult to click small areas like checkbox or radio button.
Note: The attribute of the <label> tag and the id attribute of the <input> tag should be the same in order to connect them.
The name attribute is also important in the <input> tag as it displays the name of that input field. Also if the name attribute is not specified, the values inserted by the user will not be sent at all for processing.
Submitting the form
Talking more about the submit attribute, we can use the predefined submit button of the <Form> element by specifying the input type to submit. The value attribute is the title of the button through which we are submitting.
Apart from this, the input values collected are provided to the form-handler which is a file or any API request that processes these values accordingly. The form handler should be specified in the action attribute.
Here’s an example through the code snippet:
Conclusion
Through this blog, we got to know about the predefined form tag provided by HTML that helps us to display a form in a very efficient and quick manner. It covered all the important parts that needed to be known while using a form tag such as label, name, input, type, and other attributes that should be specified while using a <Form> tag.
