Button Control
They interact with users usually to submit a form for processing or data transfer. They are displayed as rectangles with squared-off edges by default. These clickable buttons are made by using <input> tag. Both the <input> or <button> tag can be used to create any of the different types of buttons but the <input> tag is supported by many browsers. HTML has three types of buttons which are specified using the type attribute as shown
Submit – It creates a button that submits the form for processing or data transfer as shown
HTML code <form action=“/process.php” method=“get”> <input type=”submit” value=”Submit” /> or <button type=”submit”>Submit </button> </form> |
