左側固定，右側自適應的佈局方式(新增評論區大佬教的方法）

李鋼鐵發表於2018-10-16

一.浮動佈局

1.先讓固定寬度的div浮動！使其脫離文件流。
2.margin-left的值等於固定div的寬度相等。

   .aside{
        float: left;
        width: 200px;
        background-color: red;
    }
    .content{
        margin-left: 200px;
        background-color: blue;
    }
    
<div class="aside">
    Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
</div>
<div class="content">
    Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
</div>

二.margin的負值(3個div)

  1. 是固定寬度的div脫離文件流。
  2. 利用marin負值可以使得，後面的div可以與前面的div 保持同行顯示。

  3. 給包裹內容的div加margin-left 可以使得與左邊的文字不重疊

    .aside{
    float: left;
    margin-right: -200px;
    width: 200px;
    background-color: red;
}
.content{
    float: right;
}
.content .inner{
    margin-left: 200px;
    background-color: blue;
}

 <div class="aside">
   Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
</div>
<div class="content">
   <div class="inner">
      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
   </div>

    </div>

三.calc()計算屬性

注意：使用calc計算屬性的時候 運算子(- +等等)兩邊必須有空格

  1. 注意兩個div必須一左一右浮動。

  2. calc的寬度必須要減去的寬度要與固定寬度保持一致。

      .aside{
      float: left;
      width: 200px;
      background-color: red;
  }
  .content{
      calc:(100% - 200px);
      background-color: blue;
  }

    <div class=”aside”>

      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
   </div>
 <div class="content">
     Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.        
  </div>

四.flex佈局

  1. 需要給父級div設定display: flex屬性。
  2. 固定寬度的div設定flex: 0 0 200px即可。

  3. 內容區域的div直接寫出flex: 1即可。

    .container{
    display: flex;
}
.aside{
    flex: 0 0 200px;
    background-color: red; 
}
.content{
    flex: 1;
    background-color: blue;
}
<div class="container">
    <div class="aside">
    Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
    </div>
    <div class="content">
    Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
    </div>
</div>

五.左側浮動，右側overflow:hidden

.aside{
    width: 200px;
    float: left;
    background-color: red;
}
.content{
    overflow: hidden;
    background-color: blue;
}
<div class="aside">
        Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
    </div>
    <div class="content">
        Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore provident dolor in voluptatum tempore non, placeat obcaecati totam ut delectus libero excepturi distinctio asperiores odit nobis soluta, esse aspernatur beatae.
    </div>
