Ways to manipulate a div tag with CSS even when it lacks a class or ID attribute

Hey there! I've got this snippet of HTML code that I'm working with:

<div class="template-page-wrapper">
  <div class="templemo-content-wrapper">
    <div class="templatemo-content">
      <div class="templatemo-panels">
          <div id="dPopupBG" class="popup_BG"></div>
          <div style="height:100px;"><div>
          <div id="MainContent" class="msg" style="display: none;">  
          <div class="error display" style="display:none"><span></span></div>
          <div id="MainDocContent" class="flex"> 
             (and Here page content having more html details)
          </div>
      </div>
   </div>
  </div>
</div>

I've noticed some extra space between the header line and the MainDocContent. When I inspect it, the below tag is highlighted:

  <div style="height:100px;"><div>

I attempted to adjust the height using this CSS in my file, but it didn't work:

#dPopupBG+div{height:80px}

I'm determined to figure out a solution and learn from this experience.

Here is a method you can use, along with detailed explanations within the code:

/* These rules eliminate default margins and paddings
   from elements, while also incorporating padding and border sizes
   in the defined width calculation: */
*,
 ::before,
 ::after {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

div {
  /* Visual representation of the HTML structure: */ 
  border: 1px solid #000;
  /* Centering inline axis elements: */
  margin-inline: auto;
  /* Applying spacing around element contents/descendants: */
  padding: 0.5em;
  /* Showing parent-child hierarchy for visualization: */
  width: 90%;
}

/* Selecting all <div> elements with a class attribute,
   and styling the ::before pseudo-element: */
div[class]::before {
  /* Displaying the content of that attribute
     in the ::before pseudo-element for visualization: */
  content: attr(class);
}

/* Selecting all <div> elements with a "style" attribute
   containing "height:100px", or "height: 100px" (including whitespace):*/
div[style*="height:100px"],
div[style*="height: 100px"]{
  /* Background color to visualize hidden elements: */
  background-color: red;
  /* Hiding the element by setting display to "none";
     avoiding "!important" to override height, which may cause
     other consequences but relies on known height property-value: */
  display: none;
}

<div class="template-page-wrapper">
  <div class="templemo-content-wrapper">
    <div class="templatemo-content">
      <div class="templatemo-panels">
        <div id="dPopupBG" class="popup_BG"></div>
        <div style="height:100px;">
          <div>
            <div id="MainContent" class="msg" style="display: none;">
              <div class="error display" style="display:none"><span></span></div>
              <div id="MainDocContent" class="flex">
                (page content with more html details)
              </div>
            </div>
          </div>
        </div>
      </div>
