I have a host of hide/show areas (from the CSS Wizardry thread). I use a pair of check boxes (one styled, one hidden) to open and close them. After a while, they stop opening and closing. So, in an effort to fix this, I am trying to use sheet workers to open and close (use the sheet workers to check the hide checkbox). I struck upon the idea of "if this class of checkbox is checked, the next checkbox of that class is checked." Is this possible and how would one do that?
