html - CSS 显示 : inline-block drops to next line

Question

我有一个正在测试的简单网格。

我决定在属性选择器 [class*='col-] 中将 float: left 更改为 display: inline-block >.

我想知道为什么在使用 float: left 时有足够的空间用于 col-9 并且一切正常，但是在使用 display: inline-block 时 元素下降到下一行。

* {
    box-sizing: border-box;
}

.header {
	border: 1px solid red;
	padding: 15px;
}

.col-1 {width: 8.33%;}
.col-2 {width: 16.66%;}
.col-3 {width: 25%;}
.col-4 {width: 33.33%;}
.col-5 {width: 41.66%;}
.col-6 {width: 50%;}
.col-7 {width: 58.33%;}
.col-8 {width: 66.66%;}
.col-9 {width: 75%;}
.col-10 {width: 83.33%;}
.col-11 {width: 91.66%;}
.col-12 {width: 100%;}

[class*='col-'] {
	display: inline-block;
	padding-top: 15px;
	border: 1px solid red;
}

	<div class='header'>
		<h1>China</h1>
	</div>
	<div class='row'>
		<div class='col-3'>
			<ul>
				<li>The Flight</li>
				<li>The City</li>
				<li>The Island</li>
				<li>The Food</li>
			</ul>
		</div>
		<div class='col-9'>
			<h1>The City</h1>
			<p>Chania is the capital of the Chania region on the island of Crete. The city can be divided in two parts, the old town and the modern city.</p>
			<p>Resize the browser window to see how the content respond to the resizing.</p>
		</div>
	</div>

<div class='header'>
        <h1>China</h1>
    </div>
    <div class='row'>
        <div class='col-3'>
            <ul>
                <li>The Flight</li>
                <li>The City</li>
                <li>The Island</li>
                <li>The Food</li>
            </ul>
        </div><!--
        --><div class='col-9'>
            <h1>The City</h1>
            <p>Chania is the capital of the Chania region on the island of Crete. The city can be divided in two parts, the old town and the modern city.</p>
            <p>Resize the browser window to see how the content respond to the resizing.</p>
        </div>
    </div>

小技巧，试试这些 <!-- -->它忽略空格

编辑: 如果您想删除页眉的微小间隙:

.col-9 {
  vertical-align: top;
}
