一.浮動布局
1.先讓固定寬度的div浮動！使其脫離文檔流。
2.margin-left的值等于固定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)
.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()計算屬性
注意：使用calc計算屬性的時候 運算符(- +等等)兩邊必須有空格
注意兩個div必須一左一右浮動。
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;}.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
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>以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
