这样的事情应该做到：

.column-left{ float: left; width: 33.333%; }
.column-right{ float: right; width: 33.333%; }
.column-center{ display: inline-block; width: 33.333%; }

要使用大量列来执行此操作，您可以构建一个非常简单的网格系统。例如，这样的事情应该适用于五列布局：

.column {

    float: left;

    position: relative;

    width: 20%;



    /*for demo purposes only */

    background: #f2f2f2;

    border: 1px solid #e6e6e6;

    box-sizing: border-box;

}



.column-offset-1 {

    left: 20%;

}

.column-offset-2 {

    left: 40%;

}

.column-offset-3 {

    left: 60%;

}

.column-offset-4 {

    left: 80%;

}



.column-inset-1 {

    left: -20%;

}

.column-inset-2 {

    left: -40%;

}

.column-inset-3 {

    left: -60%;

}

.column-inset-4 {

    left: -80%;

}


<div class="container">

   <div class="column column-one column-offset-2">Column one</div>

   <div class="column column-two column-inset-1">Column two</div>

   <div class="column column-three column-offset-1">Column three</div>

   <div class="column column-four column-inset-2">Column four</div>

   <div class="column column-five">Column five</div>

</div>

或者，如果您很幸运能够仅支持现代浏览器：

.container {

    display: flex;

}



.column {

    flex: 1;



    /*for demo purposes only */

    background: #f2f2f2;

    border: 1px solid #e6e6e6;

    box-sizing: border-box;

}



.column-one {

    order: 3;

}

.column-two {

    order: 1;

}

.column-three {

    order: 4;

}

.column-four {

    order: 2;

}

.column-five {

    order: 5;

}


<div class="container">

   <div class="column column-one">Column one</div>

   <div class="column column-two">Column two</div>

   <div class="column column-three">Column three</div>

   <div class="column column-four">Column four</div>

   <div class="column column-five">Column five</div>

</div>
