1. Floating layout

The left column has a fixed width and floats to the left. The main content on the right uses margin-left to leave the width of the left column. The default width For auto, the remaining width is automatically filled.

<div class="one"></div>
 
<div class="two"></div>

        .one{
            float: left;
            width: 200px;
            height: 200px;
            background: darkcyan
        }
        .two{
            margin-left: 200px;
            height: 200px;
            background: salmon
        }

The right side has a fixed width, and the left side is adaptive in the same way. Just float the fixed column to the right and use margin-right to free up its width.

    <div class="one"></div>
    <div class="two"></div>

        .one{
            float: right;
            width: 200px;
            height: 200px;
            background: darkcyan
        }
        .two{
            margin-right: 200px;
            height: 200px;
            background: salmon
        }

2. Floating layout with negative margins (two-column version of double-wing layout)

        <div class="aside"></div>
    <div class="main">
        <div class="content"></div>
    </div>

        .aside{
            width: 300px;
            height: 100px;
            background:darkcyan;
            margin-right: -100%;
            float: left;
        }
        .main{
            width: 100%;
            float: left;
        }
        .content{
            margin-left: 300px;
            background: salmon;
        }

3. Absolute positioning

    <div class="left"></div>
    <div class="right"></div>

        .left{
            width: 200px;
            height: 200px;
            position: absolute;
            background: darkcyan
        }
        .right{
            height: 200px;
            margin-left:200px; 
            background: salmon;
        }
