css表格布局_布局秘密武器＃1：CSS表格属性

css表格布局

Right now, Flexbox is arguably THE hot new thing for layout building. Flexbox’s almost miraculous abilities to adapt to the available space has left many of us wide-eyed with possibility.

目前， Flexbox可以说是布局构建的热门新事物。 Flexbox几乎可以适应可用空间的奇迹般的功能使我们许多人大开眼界。

Nevertheless, it can’t solve all your layout problems, and moreover, it brings with it some compatibility issues with legacy browsers. There simply is no bulletproof ‘polyfill’ (fallback for older browsers) for Flexbox — currently I'm only aware of a polyfill for the 2009 version of IE: Flexie.

但是，它不能解决您所有的布局问题，而且还带来了与旧版浏览器的一些兼容性问题。 Flexbox根本没有防弹的“ polyfill”(旧浏览器的后备)-目前，我仅知道2009版IE： Flexie的polyfill 。

In many cases I've found simpler solutions using the often-ignored CSS table displays properties. These CSS properties are widely supported by all relevant browsers (note this excludes IE6 & 7), and can elegantly solve several major and small layout headaches.

在许多情况下，我发现了使用通常被忽略的CSS表显示属性的简单解决方案。这些CSS属性得到所有相关浏览器的广泛支持 (请注意，这不包括IE6和7)，并且可以很好地解决几个主要的和小的布局难题。

In case you're not 100% familiar with this technique, changing a DIVs display property can make it behave like a table or a table element.

如果您不是100％熟悉此技术，则更改DIVs display属性可以使其表现得像表或表元素。

等等什么表格布局？不好吗？ (Wait what? Tables for layout? Isn’t that bad?)

Perhaps the hottest web design topics of the early 2000's was the debate over using HTML table code as a layout tool. That was a hack and is still bad practice.

也许在2000年代初期最热门的Web设计主题是关于使用HTML表代码作为布局工具的争论。那是一个骇客，仍然是不好的做法。

Instead here we're using perfectly meaningful HTML (i.e. DIVs, SECTIONs, HEADERs, etc) and simply borrowing some useful table presentation know-how from CSS. This is precisely what CSS was designed to do, so don't feel that this is a hack or patch. It’s not.

取而代之的是，我们在这里使用的是完全有意义HTML(即DIV，SECTION，HEADER等)，并且只是从CSS借用了一些有用的表表示专有技术。这正是CSS设计的目的，所以不要认为这是黑客或补丁。不是。

使用“ display：table-cell” (Using 'display:table-cell')

In the sample below, clicking the top button you can change the display property of the three colored DIVs from block to table-cell:

在下面的示例中，单击顶部按钮，可以将三个彩色DIV的显示属性从block更改为table-cell ：

See the Pen Display table #1 by Massimo Cassandro (@massimo-cassandro) on CodePen.

见笔显示表＃1由马西莫卡桑德罗( @马西莫-卡桑德罗 )上CodePen 。

You can see how the DIVs can be horizontally arranged without requiring any float property, and that you can also access some typical table rules (just like vertical-align).

您可以看到如何在不需要任何float属性的情况下水平排列DIV，还可以访问一些典型的表规则(就像vertical-align )。

If you need some spacing, note that the classic CSS margin property doesn't have any effect on table cells: instead use border-spacing instead (it must be applied to the container table element). You can find some commented lines within the Codepen, if you want to play with those rules.

如果需要一些间距，请注意经典CSS margin属性对表格单元格没有任何影响：请改用border-spacing (必须将其应用于容器table元素)。如果您想使用这些规则，可以在Codepen中找到一些注释行。

This technique can be very useful to solve a lot of problems that prove difficult to crack other ways.

该技术对于解决许多难以用其他方式破解的问题可能非常有用。

I've picked out three simple cases where the table display properties are really valuable.

我选择了三种简单的情况，其中表显示属性确实很有价值。

But first let's look at them:

但是首先让我们看一下它们：

display property	renders as
table, inline-table	table
table-column	col
table-column-group	colgroup
table-row-group	tbody
table-header-group	thead
table-footer-group	tfoot
table-row	tr
table-cell	td
table-caption	caption

显示属性	呈现为
表，内联表	表
表格栏	关口
表列组	同事
表行组	身体
表头组	Thead
表脚组	foot
表行	TR
表格单元	d
表标题	标题

情况1。等高框 (Case 1. Equal height boxes)

I think this is one of the most frequent issues I've deal with: there are some floated boxes with unknown content and you have to make all them with equal height.

我认为这是我处理过的最常见的问题之一：有些漂浮的盒子内容不明，您必须使它们的高度相等。

I know, flexbox can easily solve this problem, but tables rules can do it too.

我知道，flexbox可以轻松解决此问题，但是表规则也可以解决。

Simply apply the display: table (or table-row) property to the container and the display: table-cell property to inner boxes. Take care to remove any float property (otherwise the table-cell property doesn't take effect).

只需将display: table (或table-row )属性应用于容器，将display: table-cell属性应用于内部框。请小心删除所有float属性(否则table-cell属性不会生效)。

HTML： (HTML:)

<div id="wrapper">
<div id="div1"></div>
<div id="div2"></div>
<div id="div3"></div>
</div>

CSS： (CSS:)

#wrapper {
display: table;
}
#wrapper div {
display:table-cell;
}

案例2.简单的旧式布局 (Case 2. Simple old-style layout)

This one is a more outdated example, but I think you might need to deal with it, as I did recently.

这是一个过时的示例，但我认为您可能需要像最近那样处理它。

Some months ago I received a graphic layout very similar to the scheme below. It needed to be compatible with IE8, and I found that the best way was to use CSS table rules:

几个月前，我收到了与以下方案非常相似的图形布局。它需要与IE8兼容，我发现最好的方法是使用CSS表规则：

See the Pen table display #3: old-style layout by Massimo Cassandro (@massimo-cassandro) on CodePen.

请参阅CodePen上的Pen 表显示＃3： Massimo Cassandro( @ massimo-cassandro )的旧式布局。

案例3.内容编排的响应式布局 (Case 3. Responsive layout with content choreography)

The previous example leads us to a new topic: is it possible to build a responsive layout with CSS table rules?

前面的示例将我们引向一个新主题：是否可以使用CSS表规则构建响应式布局？

Not only is possible, but we can also perform some content choreography tasks.

不仅可能，而且我们还可以执行一些内容编排任务。

We have already seen how changing the display property from block totable-cell of two divs can change their arrangement from vertical to horizontal.

我们已经看到了如何将显示属性从两个div的block更改为table-cell如何将其排列从垂直更改为水平。

Add to this the fact that an element with the table-header-group property is brought to the top of a table layout. In the same way, table-footer-group elements are brought to the bottom and so on. This can be unexpectedly useful when reformatting responsive layouts.

除此之外，具有table table-header-group属性的元素被带到表布局的顶部。同样，将table-footer-group元素放到底部，依此类推。重新格式化响应式布局时，这可能出乎意料的有用。

In the pen below, the header element exchanges his position with the nav element on window resize, simply changing its display property to table-header-group.

在下面的笔中， header元素与窗口调整大小上的nav元素交换位置，只需将其display属性更改为table-header-group 。

HTML： (HTML:)

<div id="wrapper">
<nav></nav>
<header></header>
<!-- rest of code -->
</div>

CSS： (CSS:)

#wrapper, header {
display: block; /* we don't really need this rule, since it is the default */
}
@media (min-width: 48em) {
#wrapper {
display: table;
}
header {
display: table-header-group;
}
}

A similar behavior occurs for the footerand the #banner2 div.

footer和#banner2 div也会发生类似的行为。

Here is a scheme of the layout: on the left the default, mobile version, and on the right the desktop version:

这是布局方案：左侧为默认移动版本，右侧为桌面版本：

And this is a running demo:

这是一个正在运行的演示：

See the Pen `display: table` layout by Massimo Cassandro (@massimo-cassandro) on CodePen.

看到笔`显示：table`布局由马西莫卡桑德罗( @马西莫-卡桑德罗 )上CodePen 。

结论 (Conclusion)

CSS table display properties are an under-rated and valuable solution for both big and little layout challenges.

CSS表格显示属性是针对大小布局挑战而被低估且有价值的解决方案。

While I may not personally choose to use them to build complex layouts, they can certainly solve many difficult problems related to portions of the layout.

尽管我可能不会亲自选择使用它们来构建复杂的布局，但它们肯定可以解决与布局的各个部分有关的许多难题。
