Check boxes are used to give your users the opportunity to select more than one option from a range of options. With the Radio Buttons, you could only select one item; with check boxes, you can select them all.
The HTML for check boxes looks like this:
<INPUT TYPE="Checkbox" Name="Browser" Value ="Firefox">Firefox
<INPUT TYPE="Checkbox" Name= "Browser" Value ="Opera ">Opera
Again, you can add a label to aid in selection:
<LABEL FOR="C1">Firefox</LABEL>
<INPUT TYPE="Checkbox" Name="Browser" ID="C1" Value="Firefox">
<LABEL FOR="C2"> Opera </LABEL>
<INPUT TYPE="Checkbox" Name="Browser" ID="C2" Value="Opera">
Check boxes and Radio buttons work in a similar way, and the HTML code is similar, too. The same points made about Radio buttons apply to check boxes. Note the TYPE used, though: Checkbox.
The above code for option buttons and checkboxes would look like this in the browser:
