html - 无论视口大小如何变化，都试图使下拉菜单与标题边缘保持一致

问题描述

我有一个有点移动响应的标题，但是有一些下拉菜单我想保持与标题元素的边缘齐平，而不管标题调整时视口大小的变化。

我尝试将这些下拉列表放在它们自己的元素中，例如 div 或部分，并从各个选择器中添加所有相同的 css，但我没有在那里取得进展。

// The Dropdown for New-units
const newUnitDropdown = document.querySelector(".new_units");
newUnitDropdown.innerHTML = `

S Fiddle 并没有做到这一点。我会将其复制到代码编辑器并使用浏览器。我有一个朋友在 JS Fiddle 中对其进行了调整，在其中使用display: inline-block修复它...在 JS Fiddle 中，而不是在浏览器中。

这是它在 iPad Pro 中的样子：

在此处输入图像描述

因此，无论 iPad Pro 视图如何，我都试图让该下拉菜单与灰色导航栏保持一致。我现在主要只担心 iPad Pro 的视图。

希望该徽标在调整大小时不会像那样破裂。这一切都来自布尔玛 CSS。

解决方案

只是一点点 CSS 调整和整合。我删除了为这四个浮动元素中的每一个设置的单独样式，并将它们添加到一个.fixed_under_header类元素中。

这个 CSS 应该可以解决问题：

.hero-body {
  position: relative;
}

.fixed_under_header {
  display: flex;
  justify-content: flex-start;
  position: absolute;
  top: 100%;
  z-index: 2;
}

.fixed_under_header > div {
  border: 1px solid black;
  height: fit-content;
}

.fixed_under_header > div + div {
  margin-left: 10px;
}

这是完整的工作解决方案：
