【问题描述】：

我是 Svelte 的新手，我非常喜欢它，在为我的项目设计顶部导航栏时，由于 Svelte 的 JS DOM 样式方法，我无法达到预期的结果。如果你能指导我，那就太好了。

标记如下

 <div class="top-nav">
        <div class="width-restriction">
            <div id="hamburger-icon">
                <HamburgerIcon /> <!-- Imported component, essentially an icon, doesn't affect styling; needs to be at the extreme left -->
            </div>
            <h1 class="head" id="logo">VKYD</h1> <!-- Logo; needs to be centered -->
            <div id="shopping-cart-icon">
                <ShoppingCartIcon /> <!-- Imported component, essentially an icon, doesn't affect styling; needs to be at the extreme right -->
            </div>
        </div>
    </div>

到目前为止，您对 css 有什么尝试？你应该发布那个。

标签： javascript html css svelte

【解决方案1】：

您可以在.width-restriction 上使用flexbox 轻松实现此目的：

.width-restriction {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

<div class="top-nav">
  <div class="width-restriction">
    <div id="hamburger-icon">
      icon-hamburger
      <!-- Imported component, essentially an icon, doesn't affect styling; needs to be at the extreme left -->
    </div>
    <h1 class="head" id="logo">VKYD</h1>
    <!-- Logo; needs to be centered -->
    <div id="shopping-cart-icon">
      icon-shop
      <!-- Imported component, essentially an icon, doesn't affect styling; needs to be at the extreme right -->
    </div>
  </div>
</div>

在 Svelte 中，您需要像这样在 style 标签中定义样式：

<style>
    .width-restriction {
        display: flex;
        justify-content: space-between;
        align-items: center;
    }
</style>

 <div class="top-nav">
     <div class="width-restriction">
         <div id="hamburger-icon">
             icon-hamburger <!-- Imported component, essentially an icon, doesn't affect styling; needs to be at the extreme left -->
         </div>
         <h1 class="head" id="logo">VKYD</h1> <!-- Logo; needs to be centered -->
         <div id="shopping-cart-icon">
             icon-shop <!-- Imported component, essentially an icon, doesn't affect styling; needs to be at the extreme right -->
         </div>
     </div>
</div>

检查REPL。

没问题啊 ;) 请不要忘记验证答案。

【解决方案2】：

我不熟悉 Svelte，但通常情况下，使用这种类型的放置很容易实现

display: flex;
justify-content: space-between;

您可以在此处查看该属性的快速演示（见页面底部）：https://developer.mozilla.org/en-US/docs/Web/CSS/justify-content

希望对你有帮助！
