要使 HTML 元素充当网格容器,您必须将 display
属性设置为 grid
或 <代码类=“w3-codespan”>内联网格。
网格容器由放置在列和行内的网格项组成。
grid-template-columns
属性定义网格布局中的列数,并且可以定义每列的宽度。
该值是一个空格分隔的列表,其中每个值定义相应列的宽度。
如果您希望网格布局包含 4 列,请指定 4 列的宽度,如果所有列应具有相同的宽度,则指定“自动”。
制作一个包含 4 列的网格:
.grid-container {
display: grid;
grid-template-columns: auto auto auto auto;
}

<h1>The grid-template-columns Property</h1>
<p>You can use the <em>grid-template-columns</em> property to specify the number of columns in your grid layout.</p>
<div class="grid-container">
<div>1</div>
<div>2</div>
<div>3</div>
<div>4</div>
<div>5</div>
<div>6</div>
<div>7</div>
<div>8</div>
</div>
</body>
</html>
注意:如果 4 列网格中有超过 4 个项目,网格将自动 添加一个新行来放置项目。
grid-template-columns
属性也可用于指定列的大小(宽度)。
设置 4 列的大小:
.grid-container {
display: grid;
grid-template-columns: 80px 200px auto 40px;
}
