如何将响应式导航栏（navbar）拆分为左中右三个区域？

我正在搭建一个评测网站，已实现响应式导航栏，现需调整布局为三个区域：左侧放置Logo，中间展示网站页面/项目入口，右侧设置登录和注册入口。以下是修改后的HTML和CSS代码：

修改后的HTML代码 #

      <li class="logo">
        <a href="#"><img src="youreview_logo.png" alt="logo"></a>
      </li>
      
      <!-- 中间页面入口菜单 -->
      <ul class="main-menu">
        <li><a href="#">Home</a></li>
        <li><a href="#">Products</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">About</a></li>
      </ul>
      
      <!-- 右侧登录注册区域 -->
      <ul class="auth-menu">
        <li><a href="#">登录</a></li>
        <li><a href="#">注册</a></li>
      </ul>
      
      <!-- 移动端菜单控制 -->
      <input type="checkbox" id="check">
      <span class="mobile-menu">
        <li><a href="#">Home</a></li>
        <li><a href="#">Products</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">登录</a></li>
        <li><a href="#">注册</a></li>
        <label for="check" class="close-menu"><i class="fas fa-times"></i></label>
      </span>
      <label for="check" class="open-menu"><i class="fas fa-bars"></i></label>
    </ul>
  </nav>
</header>

修改后的CSS代码 #

@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@700&display=swap');
* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

html {
  height: 100%;
  overflow: hidden;
  background: radial-gradient(ellipse at bottom, #1b2735 0%, #090a0f 100%);
  color: white;
}

body {
  font-family: "Poppins", sans-serif;
  --colour1: #fff;
  --colour2: #1b2735;
}

.nav-bar {
  display: flex;
  justify-content: space-between;
  align-items: center;
  width: 100%;
  list-style: none;
  position: relative;
  background: radial-gradient(ellipse at bottom, #1b2735 0%, #090a0f 100%);
  padding: 12px 20px;
  z-index: 1;
}

.logo img {
  width: 60px;
}

/* 中间主菜单样式 */
.main-menu {
  display: flex;
  list-style: none;
}

.main-menu li {
  padding: 0 30px;
}

/* 右侧登录注册菜单样式 */
.auth-menu {
  display: flex;
  list-style: none;
}

.auth-menu li {
  padding: 0 15px;
}

/* 通用链接样式 */
.nav-bar li a {
  display: inline-block;
  text-decoration: none;
  color: white;
  text-align: center;
  transition: 0.15s ease-in-out;
  position: relative;
  text-transform: uppercase;
}

.nav-bar li a::after {
  content: "";
  position: absolute;
  bottom: 0;
  left: 0;
  width: 0%;
  height: 1px;
  background-color: white;
  transition: 0.15s ease-in-out;
}

.nav-bar li a:hover:after {
  width: 100%;
}

/* 移动端菜单控制 */
.open-menu, .close-menu {
  position: absolute;
  color: white;
  cursor: pointer;
  font-size: 1.5rem;
  top: 50%;
  right: 20px;
  transform: translateY(-50%);
  display: none;
}

.close-menu {
  top: 20px;
  right: 20px;
}

#check {
  display: none;
}

.mobile-menu {
  display: none;
}

@media(max-width: 610px) {
  /* 隐藏桌面端菜单 */
  .main-menu, .auth-menu {
    display: none;
  }
  
  /* 移动端菜单样式 */
  .mobile-menu {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    width: 80%;
    height: 100vh;
    position: fixed;
    top: 0;
    right: -100%;
    z-index: 100;
    background-color: var(--colour2);
    transition: all 0.2s ease-in-out;
    list-style: none;
  }
  
  .mobile-menu li {
    margin-top: 40px;
  }
  
  .mobile-menu li a {
    padding: 10px;
  }
  
  .open-menu, .close-menu {
    display: block;
  }
  
  #check:checked ~ .mobile-menu {
    right: 0;
  }
}

核心改动说明 #

• 将原有的单一menu拆分为三个独立区域：.logo（左侧）、.main-menu（中间）、.auth-menu（右侧），通过justify-content: space-between实现三分布局
• 统一导航链接样式，减少代码冗余
• 移动端单独维护整合式菜单，保证移动端导航体验的完整性
• 修复原代码中columns的拼写错误（改为color）
