如何使填充响应

Question

我是学习 HTML 和 CSS 的新手，我真的很难适应响应式设计。我想让我的导航栏响应，我认为最好的方法是编辑填充。如果有人能给我一些指点，我将不胜感激。

.navbar-left {
  float: left;
  font-size: 16px;
  color: black;
  text-align: center;
  padding: 36px 29px;
  text-decoration: none;
  font-family: "Lucida Sans Unicode", "Lucida Grande", sans-serif;
}

.navbar-center {
  float: left;
  font-size: 30px;
  color: black;
  text-align: center;
  padding: 27px 311px;
  text-decoration: none;
  font-family: "Lucida Sans Unicode", "Lucida Grande", sans-serif;
}

.navbar-right {
  float: left;
  font-size: 16px;
  color: black;
  text-align: center;
  padding: 36px 29px;
  text-decoration: none;
  font-family: "Lucida Sans Unicode", "Lucida Grande", sans-serif;
}

.navbar-left:hover,
.navbar-right:hover {
  background-color: #f8f8f8;
}

<nav>
  <a class="navbar-left" href="bio.html">About</a>
  <a class="navbar-left" href="resume.html">Resume</a>
</nav>

<nav>
  <a class="navbar-center" href="index.html">Sydnie Knowlton</a>
</nav>

<nav>
  <a class="navbar-right" href="works.html">Portfolio</a>
  <a class="navbar-right" href="contact.html">Contact</a>
</nav>

Answer 1

将三个 nav 的宽度设置为 33.33% 并将它们全部向左浮动

不要依赖侧边距，使用width:50%所以nav里面的两个链接填满里面的所有space，text-align:center居中内容

* {
  box-sizing: border-box;
}

nav {
  width: 33.33%;
  float: left;
}

.navbar-left {
  float: left;
  font-size: 16px;
  color: black;
  text-align: center;
  padding: 36px 2%;
  text-decoration: none;
  font-family: "Lucida Sans Unicode", "Lucida Grande", sans-serif;
  width: 50%;
}

.navbar-center {
  float: left;
  font-size: 30px;
  color: black;
  text-align: center;
  padding: 27px 0;
  text-decoration: none;
  font-family: "Lucida Sans Unicode", "Lucida Grande", sans-serif;
  text-align: center;
}

.navbar-right {
  float: right;
  font-size: 16px;
  color: black;
  text-align: center;
  padding: 36px 2%;
  text-decoration: none;
  font-family: "Lucida Sans Unicode", "Lucida Grande", sans-serif;
  width: 50%;
}

.navbar-left:hover,
.navbar-right:hover {
  background-color: #f8f8f8;
}

<nav>
  <a class="navbar-left" href="bio.html">About</a>
  <a class="navbar-left" href="resume.html">Resume</a>
</nav>

<nav>
  <a class="navbar-center" href="index.html">Sydnie Knowlton</a>
</nav>

<nav>
  <a class="navbar-right" href="works.html">Portfolio</a>
  <a class="navbar-right" href="contact.html">Contact</a>
</nav>
