You can set a checkbox or radio button to be checked by default using the checked
attribute.
To do this, just add the word checked
to the inside of an input element. For example:
<input type="radio" name="test-name" checked>
Set the first of your radio buttons and the first of your checkboxes to both be checked by default.
