Clicking this element should NOT make it go red.

Clicking the following form field should have no effect:

Button 1:

Button 2:

Once you release the mouse button or space bar, the buttons should return to normal.

Checkbox: Clicking the checkbox, or focussing it and holding down the space bar, should make the checkbox turn green. Clicking this text should also make the checkbox go green (but shouldn't affect the text), and should toggle the state of the checkbox.

Radio Button: Clicking the radio button, or focussing it and holding down the space bar, should make the radio button turn green. Clicking this text should also make the radio button go green (but shouldn't affect the text) and should check the radio button if it isn't already.

Clicking blank areas of the page should have no effect.

Here is another radio button paired with the one above if needed for testing:
