Choose an identifier from a CSS class

I've been experimenting with a code pen that I stumbled upon: http://codepen.io/surjithctly/pen/pLDwe

When I encase the checkbox in a div with the class "mynav," it stops functioning as intended. How do I implement the specified styling for the checkbox if it's enclosed within a div with the class "mynav"?

#toggle:checked ~ .message {
  top: 0;
}

#toggle:checked ~ .container {
  margin-top: 250px;
}

Answer №1

Unfortunately, achieving this with CSS alone is not possible. The method you are currently using, known as the "checkbox hack," requires the elements to be adjacent siblings of the checkbox in order to be selected by the general sibling selector ~.

If you must maintain your new markup structure, the only practical solution would be to incorporate JavaScript.
