javascript - 响应式中心导航栏

Question

我的目标是制作一个以网页为中心的导航栏，并且像这里一样在堆栈中进行响应。
到目前为止，我通过一些研究和教程设法制作了一个响应式导航栏，但它会扩展到 Angular 落的尽头。
我试图像处理内容一样将它包装在一个容器中，但它将整个导航栏限制在中间。
然后尝试向左右添加边距，但是当我进入较小的屏幕时，它变得很难看。
所以我希望你的意见如何解决它，或者是否有其他一些首选的方式来做导航栏。

const toggleButton = document.getElementsByClassName('toggle-button')[0]
const navbarLinks = document.getElementsByClassName('navbar-links')[0]

toggleButton.addEventListener('click', () => {
  navbarLinks.classList.toggle('active')
})

* {
  box-sizing: border-box;
}

body {
  margin: 0;
  padding: 0;
}

.navbar {
  display: flex;
  position: relative;
  justify-content: space-between;
  align-items: center;
  background-color: #333;
  color: white;
}

.brand-title {
  font-size: 1.5rem;
  margin: .5rem;
}

.navbar-links {
  height: 100%;
}

.navbar-links ul {
  display: flex;
  margin: 0;
  padding: 0;
}

.navbar-links li {
  list-style: none;
}

.navbar-links li a {
  display: block;
  text-decoration: none;
  color: white;
  padding: 1rem;
}

.navbar-links li:hover {
  background-color: #555;
}

.toggle-button {
  position: absolute;
  top: .75rem;
  right: 1rem;
  display: none;
  flex-direction: column;
  justify-content: space-between;
  width: 30px;
  height: 21px;
}

.toggle-button .bar {
  height: 3px;
  width: 100%;
  background-color: white;
  border-radius: 10px;
}

@media (max-width: 800px) {
  .navbar {
    flex-direction: column;
    align-items: flex-start;
  }
  .toggle-button {
    display: flex;
  }
  .navbar-links {
    display: none;
    width: 100%;
  }
  .navbar-links ul {
    width: 100%;
    flex-direction: column;
  }
  .navbar-links ul li {
    text-align: center;
  }
  .navbar-links ul li a {
    padding: .5rem 1rem;
  }
  .navbar-links.active {
    display: flex;
  }
}

<nav class="navbar">
  <div class="brand-title">Fruit Basket</div>
  <a href="#" class="toggle-button">
    <span class="bar"></span>
    <span class="bar"></span>
    <span class="bar"></span>
  </a>
  <div class="navbar-links">
    <ul>
      <li><a href="#">Home</a></li>
      <li><a href="#">About</a></li>
      <li><a href="#">Contact</a></li>
    </ul>
  </div>
</nav>

Answer 1

将整个内容包裹在 header 中, 设置 max-width: 800px; margin: 0 auto;在 nav并移动 background-color至 header :

const toggleButton = document.getElementsByClassName('toggle-button')[0]
const navbarLinks = document.getElementsByClassName('navbar-links')[0]

toggleButton.addEventListener('click', () => {
  navbarLinks.classList.toggle('active')
})

* {
  box-sizing: border-box;
}

body {
  margin: 0;
  padding: 0;
}

header {
  background-color: #333;
}

.navbar {
  display: flex;
  position: relative;
  justify-content: space-between;
  align-items: center;
  margin: 0 auto;
  max-width: 800px;
  color: white;
}

.brand-title {
  font-size: 1.5rem;
  margin: .5rem;
}

.navbar-links {
  height: 100%;
}

.navbar-links ul {
  display: flex;
  margin: 0;
  padding: 0;
}

.navbar-links li {
  list-style: none;
}

.navbar-links li a {
  display: block;
  text-decoration: none;
  color: white;
  padding: 1rem;
}

.navbar-links li:hover {
  background-color: #555;
}

.toggle-button {
  position: absolute;
  top: .75rem;
  right: 1rem;
  display: none;
  flex-direction: column;
  justify-content: space-between;
  width: 30px;
  height: 21px;
}

.toggle-button .bar {
  height: 3px;
  width: 100%;
  background-color: white;
  border-radius: 10px;
}

@media (max-width: 800px) {
  .navbar {
    flex-direction: column;
    align-items: flex-start;
  }

  .toggle-button {
    display: flex;
  }

  .navbar-links {
    display: none;
    width: 100%;
  }

  .navbar-links ul {
    width: 100%;
    flex-direction: column;
  }

  .navbar-links ul li {
    text-align: center;
  }

  .navbar-links ul li a {
    padding: .5rem 1rem;
  }

  .navbar-links.active {
    display: flex;
  }
}

<header>
  <nav class="navbar">
    <div class="brand-title">Fruit Basket</div>
    <a href="#" class="toggle-button">
      <span class="bar"></span>
      <span class="bar"></span>
      <span class="bar"></span>
    </a>
    <div class="navbar-links">
      <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">Contact</a></li>
      </ul>
    </div>
  </nav>
</header>

margin: 0 auto居中 nav和 max-width限制它的宽度。如果您希望它更宽，只需更改此属性。
