WordPress remove empty span tag

I am using a WordPress editor and I want to display an icon inside a "span" -tag like this:

<div id="question1" class="box-around">
   <div class="box-left"><span class="fa fa-search" aria-hidden="true"> </span></div>
   <div class="box-right">
      <h3>Some Heading</h3>
      Some Text
      <span id="question1-answer"> </span>
    </div>
</div>

Whenever I make changes to "visual" it removes the "span" -tag and looks like this:

<div id="question1" class="box-around">
  <div class="box-left"></div>
   <div class="box-right">
      <h3>Some Heading</h3>
       Some Text
       <span id="question1-answer"> </span>
    </div>
</div>

Oddly enough, the range at the bottom (id = "question1-answer") is preserved. Am I missing something? I already tried to set the "& nbsp" space inside the tag to be converted to "(actual white space) after changing the text in" visual "and use different tags as well.

Thank!

Add this code to your active theme's functions.php.



function override_mce_options($initArray) {
    $opts = '*[*]';
    $initArray['valid_elements'] = $opts;
    $initArray['extended_valid_elements'] = $opts;
    return $initArray;
} 
add_filter('tiny_mce_before_init', 'override_mce_options');

A little more specific is to allow empty tags if they have an id, name, class, or style attribute:

function override_mce_options($initArray) {
  $opts = '*[id|name|class|style]';
  $initArray['valid_elements'] .= ',' . $opts;
  $initArray['extended_valid_elements'] .= ',' . $opts;
  return $initArray;
}
add_filter('tiny_mce_before_init', 'override_mce_options');


Maybe I am doing something wrong, but it works for me. However, I'm sure there is a better solution - it would be nice to add only one specific tag to the valid elements.
