To set a checkbox use type="checkbox" of element input (in the same way as for radio buttons). Checkboxes have some special rules:
type="checkbox" - attribute type must be set as checkbox, this way we make browser understand that we set a checkbox.
name="ez", name="hr", name="sv" - Attribute names must be different for all checkboxes's elements of a current group.
value="" - attribute value is not required here. We can omit it or make empty.
checked="checked" - attribute checked set if a checkbox is checked.
Tag <label> defines a label for an <input> element. Tag <label> provides useful effect: a mouse click activates or disactivates a checkbox of required input field.
Description of whole group of checkboxes must be outside first <label> tag for a checkbox and before first checkbox.
