html - DIV 卡在页面左侧

Question

我在页面左侧创建了一个固定菜单，现在我想通过设置左右 CSS 值的值在右侧创建一个“内容”区域，但是内容不会相应调整。

JSFiddle

body {
  margin: 0px;
  background-image: url(_assets/bg_2.png);
  background-position: center;
  background-repeat: repeat;
  height: 300%;
}
@font-face {
  src: url("_assets/Socialico.ttf");
  font-family: nav-social-1;
}
@font-face {
  src: url("_assets/Socialico Plus.ttf");
  font-family: nav-social-2;
}
@font-face {
  src: url("_assets/Century Gothic.ttf");
  font-family: nav-item;
}

Answer 1

给 .sidebar-menu div 一个 fixed 的位置，让它脱离文档流。所以你的 .content=wrapper div 会忽略它并将自己定位在视口(viewport)的左侧。你可以给它一个 250px 的 margin-left:

.content-wrapper{
    margin-left:250px;  
}

为了弥补这一点，但如果您只想将菜单固定在视口(viewport)的左侧，我建议改为 float 它(和您的内容包装器)。
