我无法让我的导航占用我的 flexbox。导航仅占据其所在框的一小部分

Question

运行时的代码没有像我希望的那样填充 flexbox，我想继续对尺寸变化做出更快的响应。我从很多地方提取了资源，但仍然找不到它不起作用的原因。我来这里是因为我也经常使用这个网站来帮助完成其他工作。

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

// Close the dropdown 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');
      }
    }
  }
}

    .column, .columna, .columnab, .columnb {

        box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
        z-index: 1;
    }

    .dropdown-content a {

Answer 1

欢迎来到堆栈溢出。您的问题不是很清楚，您能否通过指向 classes 或 maing img.

更精确地说明您要填写的元素

现在我调整了你的下拉菜单的宽度 class 不是 100%

.dropdown{
  width: 100%;
}
.dropdown button {
  width: 100%;
}

根据我理解的DEMO。

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

// Close the dropdown 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');
      }
    }
  }
}

/* Header */
    .column, .columna, .columnab, .columnb {
        align-items: center;
        text-align: center;
        border: solid;
        border-width: thin;
        max-height: 20em;
    }
    .column {
        flex: 33%;
    }
    .columna {
        width: 100%;
        
    }
    .columnab {
        width: 22%;
        
    }
    .columnb {
        width: 17%;
        
    }
    .row {
        min-height: 10em;
        display: flex;
        flex-wrap: wrap;
        background-color: #FF9176;
    }
/* Navigation Section */
    .dropbtn {

        z-index: 1;
    }

我无法让我的导航占用我的 flexbox。导航仅占据其所在框的一小部分

I am having trouble with getting my navigation to take up my flexbox. The navigation only takes up a small portion of the box it's in
