title: Toggle multiple Div names/content by one button click
body: <p>i have 4 different divs in german. By clicking a button, i want to hide the german divs and instead show the english divs, which are hidden before. </p>
  
  <p>There are ways to change between 2 divs, but how can i change mulitple divs at the same time by clicking one time on one button?</p>
