Question

我有一个旧程序，它从Java源文件生成html文件，以提供从使用到定义和交叉引用的超链接。生成的文件使用PRE html标记来保留源格式。交叉引用在Javascript菜单中运行良好，但不再支持这些菜单，因此我可以使用css菜单解决方案。

问题是我的菜单相对于PRE文本显示在垂直对齐中。我尝试调整风格没有效果。任何帮助表示赞赏。

这是我的css：

.dropbtn {
    color: black;
    /*padding: 16px;*/
    //font-size: 16px;
    border: none;
    cursor: pointer;
}

/* The container <div> - needed to position the dropdown content */
.dropdown {
    position: relative;
    display: inline-block;
}

/* Dropdown Content (Hidden by Default) */
.dropdown-content {
    display: none;
    position: absolute;
    left: 30px;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}

/* Links inside the dropdown */
.dropdown-content a {
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;
}

/* Change color of dropdown links on hover */
.dropdown-content a:hover {
    background-color: #cde
}

/* Show the dropdown menu (use JS to add this class to the .dropdown-content container when the user clicks on the dropdown button) */
.show {
    display:block;
}

这是我的html正文：

Some text <div class="dropdown">
  <a href="#" onclick="myFunction('myDropdown1')" class="dropbtn">Dropdown</a>
  <div id="myDropdown1" class="dropdown-content">
    <a href="#2">Link 1</a>
    <div class="dropdown">
    <a href="#" onclick="myFunction('myDropdown3')" class="dropbtn">Link1.1</a>
    <div id="myDropdown3" class="dropdown-content">
        <a href="#2">Link 1.2</a>
    </div>
    </div>
    <a href="#3">Link 2</a>
    <a href="#1">Link 3</a>
  </div>
</div> around a button.

Write some text around a button<div class="dropdown">
  <button onclick="myFunction('myDropdown2')" class="dropbtn">Link</button>
  <div id="myDropdown2" class="dropdown-content">
    <a href="#2">Link 4</a>
    <a href="#3">Link 5</a>
    <a href="#1">Link 6</a>
  </div>
</div>Let see if this works!

这是我最后的脚本部分：

/* When the user clicks on the button, 
toggle between hiding and showing the dropdown content */
function myFunction(dropDownLink) {
    document.getElementById(dropDownLink).classList.toggle("show");
}

// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
  if (!event.target.matches('.dropbtn')) {

    var dropdowns = document.getElementsByClassName("dropdown-content");
    var i;
    for (i = 0; i < dropdowns.length; i++) {
      var openDropdown = dropdowns[i];
      if (openDropdown.classList.contains('show')) {
        openDropdown.classList.remove('show');
      }
    }
  }
}
