In HTML, the BUTTON tag is used to add a button control on the form. A button control can be used to perform various tasks, such as submitting or resetting the details of the form.
The BUTTON tag can be used with the conjunction of FORM tag to display the controls on the form. A button control can also be placed on the form by using the INPUT tag, but the difference is that you do not have the scope to change the appearance of the button control, except changing the text on the button control. However, you can change the appearance of the button control in case you have created the button control by using the BUTTON tag.
The button control is created by using the opening and the closing tags of the BUTTON tag. The text, image, or any multimedia embedded between the opening and the closing tags of the BUTTON tag become the content of the button control.
The BUTTON tag provides a type attribute that allows you to create three kinds of button controls i.e. submit button, reset button, and normal button. The submit button is used to submit the form, whereas the reset button is used to erase all the text entered in the text box of the form and set the default values.
The submit button is created by setting the type attribute to submit, the reset button is created by setting the type attribute to reset, and the normal button is created by setting the value of the type attribute to button.
The following table describes the various attributes of the BUTTON tag :
