Multiple Dropdown Columns

[progolf]

I'm trying to add a couple of dropdown columns to this script.  it works fine on chrome but i get a strange white line between the columns just after "about us". I created a test page www.hkprogolf.com/test.html.  If you view this page in safari and hover over "about us" you can see the line but its okay in chrome. Just wondering if  the code is correct.

<div class="navbar">
  <a href="#home">Home</a>
  <a class="nav-link active" href="">Active Page</a>
  <div class="dropdown">
    <button class="dropbtn">Club Membership  
    </button>
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div> 
  <a href="#pag2">Member Tournaments</a>
  <div class="dropdown">
    <button class="dropbtn">Golf Training
    </button>
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div> 
  <div class="dropdown">
    <button class="dropbtn">About Us
    </button>
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div> 
  <a href="#pag3">Photo Gallery</a>
</div>
