I need to somehow detect that the user has pressed a browsers back button and reload the page with refresh (reloading the content and CSS) using jquery.

How to detect such action via jquery?

Because right now some elements are not reloaded if I use the back button in a browser. But if I use links in the website everything is refreshed and showed correctly.

IMPORTANT!

Some people have probably misunderstood what I want. I don't want to refresh the current page. I want to refresh the page that is loaded after I press the back button. here is what I mean in a more detailed way:

  1. user is visiting page1.
  2. while on page1 - he clicks on a link to page2.
  3. he is redirected to the page2
  4. now (Important part!) he clicks on the back button in browser because he wants to go back to page1
  5. he is back on the page1 - and now the page1 is being reloaded and something is alerted like "You are back!"

You can use pageshow event to handle situation when browser navigates to your page through history traversal:

window.addEventListener( "pageshow", function ( event ) {
  var historyTraversal = event.persisted || 
                         ( typeof window.performance != "undefined" && 
                              window.performance.navigation.type === 2 );
  if ( historyTraversal ) {
    // Handle page restore.
    window.location.reload();
  }
});

Note that HTTP cache may be involved too. You need to set proper cache related HTTP headers on server to cache only those resources that need to be cached. You can also do forced reload to instuct browser to ignore HTTP cache: window.location.reload( true ). But I don't think that it is best solution.
