In this tutorial i will talk about CheckBox in HTML Forms.

The checked attribute is a boolean attribute.

When present, it specifies that an input element should be pre-selected (checked) when the page loads.

input elements of type checkbox are rendered by default as boxes that are checked (ticked) when activated, like you might see in an official government paper form. The exact appearance depends upon the operating system configuration under which the browser is running. Generally this is a square but it may have rounded corners. A checkbox allows you to select single values for submission in a form (or not).
