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. Mollitia labore facere delectus quaerat expedita, tenetur recusandae tempora eos natus suscipit voluptatum necessitatibus soluta voluptates modi ullam. Ab minima similique, illum!
</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;
}
.content{
float: right;
calc:(100% - 200px);
}
<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。
body{
display: flex;
}
.aside{
flex: 0 0 200px;
background-color: red;
}
.content{
flex: 1;
background-color:blue;
}
<div class="aside">
Lorem ipsum dolor sit amet, consectetur adipisicing elit. Fugiat magnam nihil nostrum, similique dolor deserunt voluptatem pariatur alias, ipsum, error quos quo accusantium. Deleniti neque, pariatur voluptates maxime quam perferendis!
</div>
<div class="content">
Lorem ipsum dolor sit amet, consectetur adipisicing elit. Consectetur tempora sequi minima, placeat esse nulla dolor dolores praesentium illo, distinctio fugiat eligendi debitis animi ut impedit, magni vitae officiis, architecto.
</div>
