基于本文中描述的方法，我创建了.Less dynamic解决方案:

Html:

<div id="container3">
    <div id="container2">
        <div id="container1">
            <div id="col1">Column 1</div>
            <div id="col2">Column 2</div>
            <div id="col3">Column 3</div>
        </div>
    </div>
</div>

少:

/* Changes these variables to adjust your columns */
@col1Width: 60%;
@col2Width: 1%;
@padding: 0%;

/* Misc variable. Do not change */
@col3Width: 100% - @col1Width - @col2Width;

#container3 {
    float: left;
    width: 100%;
    overflow: hidden;
    background-color: red;
    position: relative;

    #container2 {
        float: left;
        width: 100%;
        position: relative;
        background-color: yellow;
        right: @col3Width;

        #container1 {
            float: left;
            width: 100%;
            position: relative;
            right: @col2Width;
            background-color: green;

            #col1 {
                float: left;
                width: @col1Width - @padding * 2;
                position: relative;
                left: 100% - @col1Width + @padding;
                overflow: hidden;
            }

            .col2 {
                float: left;
                width: @col2Width - @padding * 2;
                position: relative;
                left: 100% - @col1Width + @padding + @padding * 2;
                overflow: hidden;
            }

            #col3 {
                float: left;
                width: @col3Width - @padding * 2;
                position: relative;
                left: 100% - @col1Width + @padding + @padding * 4;
                overflow: hidden;
            }
        }
    }
}

将display: grid添加到父节点

下面的代码提供了设置滚动div的最小高度的能力，并通过使用flex使其具有其父div的100%高度。

CSS:

.main {
  display: flex;
  flex-direction: column;
}

.scroll {
  overflow: auto;
  flex: 1 0 50px;
}

HTML:

<div class="main">
  <div class="scroll">
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

(在另一个回答中提到了Dmity的Less代码)我猜这是某种“伪代码”?

据我所知，尝试使用人造柱技术应该可以做到这一点。

希望这对你有所帮助。

对于父节点:

display: flex;

您应该添加一些前缀，例如http://css-tricks.com/using-flexbox/。

正如@Adam Garner所指出的，align-items:拉伸;不需要。它的用法也适用于父母，而不是孩子。如果你想定义儿童拉伸，你使用align-self。

.parent { 背景:红色; 填充:10 px; 显示:flex; ｝ .other-child { 宽度:100 px; 背景:黄色; 身高:150 px; 填充:.5rem; ｝ .child { 宽度:100 px; 背景:蓝色; ｝ < div class = "父" > < div class = "另一个孩子“> 仅用于拉伸父节点 < / div > < div class = "孩子" > < / div > < / div >

你使用CSS Flexbox

.flex-container { display: flex; background-color: DodgerBlue; } .flex-container > div { background-color: #f1f1f1; margin: 10px; padding: 20px; font-size: 30px; } <!DOCTYPE html> <html> <head> </head> <body> <div class="flex-container"> <div>1</div> <div>2</div> <div>3</div> </div> <p>A Flexible Layout must have a parent element with the <em>display</em> property set to <em>flex</em>.</p> <p>Direct child elements(s) of the flexible container automatically becomes flexible items.</p> </body> </html>
