【问题描述】:
我想要一个菜单栏,其中所有菜单项的宽度都相同(与最宽的一样宽)。菜单项的数量可能会有所不同。如果有多余的空间,菜单应在其容器内居中。
如果项目不能放在一行中,它们可能会换行,但它们仍应具有相同的宽度。像这样的:
| [ short ] [loooooooong] [ between ] |
| [ wrapped ] |
我可以用 CSS 做到这一点吗?
我尝试使用 display:grid,但失败了:
.container {
border: 1px solid black;
display:inline-block;
}
.menu {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(50px, -webkit-max-content));
grid-template-columns: repeat(auto-fit, minmax(50px, max-content));
justify-content: center;
grid-gap: 10px;
background: #eee;
}
.item {
border: 1px solid #aaa;
background: yellow;
white-space: nowrap;
}
<div class="container">
<h2>Two items</h2>
<p>
These should have equal widths (as wide as the widest one is) and be centered within the container.
</p>
<div class="menu">
<div class="item">Short</div>
<div class="item">Looooooooooong</div>
</div>
<p>
They are centered all right, but don't have equal widths.
</p>
<h2>Three items</h2>
<p>
These three should also have same width with each other.
</p>
<div class="menu">
<div class="item">First item</div>
<div class="item">Second item</div>
<div class="item">Third</div>
</div>
<p>
They are centered all right, but don't have equal widths.
</p>
<h2>So many items that they won't fit on one line</h2>
<p>
These should also have equal widths, but they should wrap to the next row. I don't care whether the second row is centered as long as the items are aligned with the row above.
</p>
<div class="menu">
<div class="item">First item</div>
<div class="item">Second item</div>
<div class="item">Third item, a longer one</div>
<div class="item">Fourth item</div>
<div class="item">Fifth item</div>
<div class="item">Sixth item</div>
<div class="item">Seventh item</div>
<div class="item">Eight item</div>
<div class="item">Ninth item</div>
<div class="item">Tenth item</div>
<div class="item">Item number 11</div>
<div class="item">Item number 12</div>
<div class="item">Item number 13</div>
<div class="item">Item number 14</div>
<div class="item">Item number 15</div>
<div class="item">Item number 16</div>
<div class="item">Item number 17</div>
<div class="item">Item number 18</div>
<div class="item">Item number 19</div>
<div class="item">Item number 20</div>
<div class="item">Item number 21</div>
<div class="item">Item number 22</div>
<div class="item">Item number 23</div>
</div>
<p>
They have equal widths, but the width is the min width given in minmax and the content doesn't fit within the item.
</p>
</div>

Centered table-like layout with columns of equal widths using CSS? 的问题类似,但按钮的数量是固定的,没有换行。
不需要是 display:grid。
【问题讨论】:

您探索过
flex-box解决方案吗? -
可能 flex-box 是要走的路,但对包装最近的浏览器/设备的支持很差,这就是我个人避免它的原因。除了包装,这里是前两种情况的解决方案。如果您需要我解释,请告诉我。 codepen.io/anon/pen/qXZGrg
-
我不认为有一个纯 css 解决方案可以做到这一点,因此它也适用于多行 - flex 不能这样做以使所有内容都与最长的项目一样长 - 通常如果它要匹配最长的项目,它只会是每行或每列,除非你改变了基础,那么它只会匹配基础
-
确实,很确定这不是 any 布局方法。
-
是的,我也尝试过 flexbox,但也无法做到我想要的。我想我需要使用 javascript 或使用我所拥有的。感谢 cmets!
