一.浮动布局
1.先让固定宽度的div浮动!使其脱离文档流。
2.margin-left的值等于固定div的宽度相等。
.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的负值(3个div)
- 是固定宽度的div脱离文档流。
- 利用marin负值可以使得,后面的div可以与前面的div 保持同行显示。
-
给包裹内容的div加margin-left 可以使得与左边的文字不重叠
.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()计算属性
注意:使用calc计算属性的时候 运算符(- +等等)两边必须有空格
- 注意两个div必须一左一右浮动。
-
calc的宽度必须要减去的宽度要与固定宽度保持一致。
.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布局
- 需要给父级div设置display: flex属性。
- 固定宽度的div设置flex: 0 0 200px即可。
-
内容区域的div直接写出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.左侧浮动,右侧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>
