HTML Input Tag

HTML Input Tag

The HTML <input> tag is used to represent a form input control in HTML document. This form input control facilitate user to input data and communicate with a website or application. Let's take an example of an HTML form with three input fields, two text fields and one button for submission.

HTML Input Tag Example

Example of HTML input tag.

<form action="#">  
Name: <input type="text" name="name"  placeholder="enter name..."><br>  
Email: <input type="email" name="email" placeholder="enter Email..."><br>  
<input type="submit" value="Submit">  
</form>  

Output

   Name: 
   Email: 
    

Click the "Submit" button for sending the form-data to a page on the server.

Points to remember

• Use the input element within the form element to declare input control that allow user to enter data.
• The input element is empty. It contains attributes only. There is no need of an end tag in HTML.
• If you want to define labels for input element, use the label element with each input tag.

Tips and Notes

Note: The <input> element is empty, it contains attributes only.

Tip: Use the <label> element to define labels for <input> elements.
