HTML – CheckBox

Creating check boxes:

• A check box is either selected or not.
• Unlike radio buttons, check boxes can be deselected.
• A check box can be unselected if the user clicks inside the check box.
• On the other hand, a radio button cannot be deselected if you click on the radio button.
• A radio button can be deselected by clicking on some other radio button choice.
• To create a check box, use the <input> tag and set the type attribute to “checkbox” as:

<input type="checkbox">

Naming a check box: using ‘name’ attribute, we can value the checkbox to process in the form

<input type="checkbox" name="language"> HTML

Note: You can’t use a different name for every check box you specify in the list. Related choices represented with check boxes can be grouped with a same name.

Select languages known:
	<input type="checkbox" name="language">.Net
	<input type="checkbox" name=" language ">Java
	<input type="checkbox" name=" language ">Python

Setting value: By default, when a check box is selected and that choice is submitted to the server, the value of the check box is “on.” You can, however, assign a different value to a check box, by using the value attribute.

Select languages known:
		<input type="checkbox" name="language" value=”dotnet”>.Net
		<input type="checkbox" name=" language" value = “java”>Java
		<input type="checkbox" name=" language" value = “python”>Python

Default selection: We can check the option among specified when user have to select at least one among all.
