Css 网格和汉堡包菜单

Question

我正在学习 css 总的来说，我非常失败，-非常努力...

我想用我的 css 网格做一件简单的事情，只是从右到左而不是从左到右动画隐藏菜单，但我不知道我必须改变什么才能做到这一点..

你们能帮帮我吗？这里是fiddle：https://jsfiddle.net/xwvL2a70/

/* grid */
.container {
  display: grid;
  grid-template-columns: 1fr;
  grid-gap: 10px;
}

/* items */
.container > * {
  color: #353535;
  font-size: 1.2em;
  line-height: 1.5;
  padding: 20px;
  background: #d0cfc5;
}

/* nav styles */
.container nav {
  background: #136fd2;
}

nav ul {
  list-style: none;
  margin: 0;
  padding: 0;
}

nav a {
  color: #d0cfc5
}

nav a:hover {
  text-decoration: none;
}

/* media query for grid layout */
@media only screen and (min-width: 600px) {

  /* grid */
  .container {
    grid-template-columns: repeat(4, 1fr);
  }

  /* specific item styles */
  .container header,
  .container nav,

    display: inline-block;
    padding: 0 20px 0 0;
  }

  /* hide toggle */
  .toggle {
    display: none;
  }

}

/* media query for nav styles */
@media only screen and (max-width: 599px) {

    #nav {
      transition: transform .3s ease-in-out;
      top: 0;
      bottom: 0;   
      min-height: 100vh; /* override Safari bug */
      position: fixed; /* or choose `absolute` depending on desired behavior*/
      width: 300px;
      left: -340px;
    }

    #nav:target {     
      transform: translateX(340px);
    }

    .close {
      text-align: right;
      display: block;
      text-decoration: none;
      font-size: 3em;
      position: relative;
      top: -30px;
    }

  .open {
    text-align: left;
  }

}

Answer 1

您只需将 left: -340px; 更改为 right: -340px;，然后将 transform: translateX(340px); 更改为 transform: translateX(-340px);。这两个都在媒体查询中。

这是一个工作示例（如果您在全屏模式下查看并缩小 window 宽度以进行预览）：

/* grid */
.container {
  display: grid;
  grid-template-columns: 1fr;
  grid-gap: 10px;
}

/* items */
.container > * {
  color: #353535;
  font-size: 1.2em;
  line-height: 1.5;
  padding: 20px;
  background: #d0cfc5;
}

/* nav styles */
.container nav {
  background: #136fd2;
}

nav ul {
  list-style: none;
  margin: 0;
  padding: 0;
}

nav a {
  color: #d0cfc5
}

nav a:hover {
  text-decoration: none;
}

/* media query for grid layout */
@media only screen and (min-width: 600px) {
    
  /* grid */
  .container {
    grid-template-columns: repeat(4, 1fr);
  }
  
  /* specific item styles */
  .container header,
  .container nav,
  .container footer {
    grid-column: span 4;
  }
  .container section {
    grid-column: span 3;
  }
  
  /* nav styles */
  nav ul li {
    display: inline-block;
    padding: 0 20px 0 0;
  }
  
  /* hide toggle */
  .toggle {
    display: none;
  }
  
}

/* media query for nav styles */
@media only screen and (max-width: 599px) {
  
    #nav {
      transition: transform .3s ease-in-out;
      top: 0;
      bottom: 0;   
      position: fixed;
      width: 300px;
      right: -340px;
    }
  
    #nav:target {     
      transform: translateX(-340px);
    }
  
    .close {
      text-align: right;
      display: block;
      text-decoration: none;
      font-size: 3em;
      position: relative;
      top: -30px;
    }
  
  .open {
    text-align: left;
  }
  
}
