I have tried using the #active:checked ~.dropdown to connect the dropdown action of appearing and disappearing on press, to the menu/close icon checkbox but it does not seem to work. Do you think making this with only html css feasible or do i have to use Java script to achieve results. As for a month or so i have been practicing css and html seeing how far i can go without it, do you think its about time i start javascript ?
