在引导中缺少可见-**和隐藏-**

在Bootstrap v3中，我经常使用hidden-**类结合clearfix来控制不同屏幕宽度的多列布局。例如,

我可以在一个DIV中组合多个hidden-**，使我的多列在不同的屏幕宽度上正确显示。

举个例子，如果我想显示几行产品照片，在大屏幕上每行4张，在小屏幕上3张，然后在非常小的屏幕上2张。产品照片可能是不同的高度，所以我需要clearfix，以确保行中断适当。

这是v3中的一个例子…

现在v4已经删除了这些类，并将它们替换为可见/隐藏-** up/down类，我似乎必须用多个div来做同样的事情。

下面是v4中的一个类似的例子……

http://jsbin.com/sagowihowa/edit?html,css,output

所以我已经从单个div到必须添加多个具有大量向上/向下类的div来实现相同的事情。

从…

<div class="clearfix visible-xs-block visible-sm-block"></div>

……

<div class="clearfix hidden-sm-up"></div>
<div class="clearfix hidden-md-up hidden-xs-down"></div>
<div class="clearfix hidden-md-down"></div>

在v4中有没有我忽略的更好的方法?

隐藏元素:

要隐藏元素，只需使用.d-none类或任何响应屏幕变化的.d-{sm,md,lg,xl,xxl}-none类之一。

要只在给定的屏幕尺寸间隔上显示一个元素，可以将.d-*-none类与.d-*-*类组合在一起，例如.d-none .d-md-block .d-xl-none .d-xxl-none将在除中型和大型设备外的所有屏幕尺寸上隐藏该元素。

Screen size Class
Hidden on all .d-none
Hidden only on xs .d-none .d-sm-block
Hidden only on sm .d-sm-none .d-md-block
Hidden only on md .d-md-none .d-lg-block
Hidden only on lg .d-lg-none .d-xl-block
Hidden only on xl .d-xl-none .d-xxl-block
Hidden only on xxl .d-xxl-none
Visible on all .d-block
Visible only on xs .d-block .d-sm-none
Visible only on sm .d-none .d-sm-block .d-md-none
Visible only on md .d-none .d-md-block .d-lg-none
Visible only on lg .d-none .d-lg-block .d-xl-none
Visible only on xl .d-none .d-xl-block .d-xxl-none
Visible only on xxl .d-none .d-xxl-block

打印显示:

使用打印显示实用工具类打印时更改元素的显示值。包括支持与响应性.d-*实用程序相同的显示值。

.d-print-none .d-print-inline .d-print-inline-block .d-print-block .d-print-grid .d-print-table .d-print-table-row .d-print-table-cell .d-print-flex .d-print-inline-flex

现在，您必须定义隐藏内容的大小

.hidden-xs-down

会对xs和更小的部分隐藏吗，只有xs

.hidden-xs-up

会隐藏一切

2016-02-11 22:56:26

不幸的是，所有hidden-*-up和hidden-*-down类都从Bootstrap中删除了(截至Bootstrap版本4 Beta，在版本4 Alpha和版本3中这些类仍然存在)。

相反，应该使用新的类d-*，如这里提到的:https://getbootstrap.com/docs/4.0/migration/#utilities

我发现这种新方法在某些情况下用处不大。旧的方法是HIDE元素，而新方法是SHOW元素。用CSS显示元素并不那么容易，因为你需要知道元素是显示为块、内联、内联块还是表等。

你可能想用下面的CSS恢复Bootstrap 3中已知的前“hidden-*”样式:

/*\
 * Restore Bootstrap 3 "hidden" utility classes.
\*/

/* Breakpoint XS */
@media (max-width: 575px)
{
    .hidden-xs-down, .hidden-sm-down, .hidden-md-down, .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, 
    .hidden-unless-sm, .hidden-unless-md, .hidden-unless-lg, .hidden-unless-xl
    {
        display: none !important;
    }

}

/* Breakpoint SM */
@media (min-width: 576px) and (max-width: 767px)
{
    .hidden-sm-down, .hidden-md-down, .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, 
    .hidden-unless-xs, .hidden-unless-md, .hidden-unless-lg, .hidden-unless-xl
    {
        display: none !important;
    } 
}

/* Breakpoint MD */
@media (min-width: 768px) and (max-width: 991px)
{
    .hidden-md-down, .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, .hidden-md-up, 
    .hidden-unless-xs, .hidden-unless-sm, .hidden-unless-lg, .hidden-unless-xl
    {
        display: none !important;
    } 
}

/* Breakpoint LG */
@media (min-width: 992px) and (max-width: 1199px)
{
    .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, .hidden-md-up, .hidden-lg-up, 
    .hidden-unless-xs, .hidden-unless-sm, .hidden-unless-md, .hidden-unless-xl
    {
        display: none !important;
    } 
}

/* Breakpoint XL */
@media (min-width: 1200px)
{
    .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, .hidden-md-up, .hidden-lg-up, .hidden-xl-up, 
    .hidden-unless-xs, .hidden-unless-sm, .hidden-unless-md, .hidden-unless-lg
    {
        display: none !important;
    } 
}

在Bootstrap 3中没有包含隐藏的类-unless-*，但它们也很有用，并且应该是自解释的。

不幸的是，这些新的引导类不像使用折叠的div上的旧类那样工作，因为他们将可见的div设置为块，开始时是可见的而不是隐藏的，如果你添加一个额外的div，折叠功能不再工作。
