Can force HTML, CSS or Bootstrap to create a button "show all"?

Commonplace thing, but can not do. Let's seem 2 div block, and another 2 behind the button "show all". Without animation, it is possible to back would not close. I know that a similar thing is done using JavaScript/Jquery, but I still have not grown up, so asking how to do this forces HTML, CSS
