Twitter引导响应块高度

Question

在我的 Twitter Bootstrap 3.2 应用程序中，我有具有响应宽度的 div 块。

但是如果我删除“行”类，由于内容长度的变化，块的高度会变得不同，所以块看起来很奇怪。检查这个宽度大于 992px 的屏幕：http://jsfiddle.net/mavent/bFcrq/13/

如果我使用“row”类，我的页面看起来不错：http://jsfiddle.net/mavent/bFcrq/15/ 但我不知道何时使用行类。因为屏幕大小不同，所以我不知道我是否可以使用每 2 个 div 或 3 个 div 的行类。

所以我的问题是，我怎样才能使这些块具有相同的高度，以便即使大小屏幕也具有漂亮的外观？

<div class="text-center"> <div class="visible-xs visible-sm">Small screen is ok, There is problem for big screens </div> <div class="well col-lg-4 col-md-4 col-sm-12 col-xs-12"> <a href=""><h2>My pretty title 1</h2><p>My subtitle which can have different number of words</p></a> </div>

编辑：还要检查大屏幕中的这种行为：http://jsfiddle.net/bFcrq/26/
即使我使用“行”类，有些块很长有些很短。
当我使用“alert-*”类时，它看起来很糟糕。

Edit2：虽然我更喜欢 CSS 解决方案，但基于 JQuery 的解决方案也适合我。

我认为这是你可以在没有 javascript 的情况下做的最好的事情：http://jsfiddle.net/V2F9E/6/

<div class="container">
    <div class="row">
        <div class="col-lg-4 col-md-6 col-xs-12">
            <h1>1</h1>
            <p>Sub</p>
        </div>
        <div class="col-lg-4 col-md-6 col-xs-12">
            <h1>2</h1>
            <p>

        <div class="clearfix visible-md-block "></div><!--This clearfix has to be set every 2 div because that's when col-md break to a new line-->

         <div class="clearfix visible-lg-block "></div><!--This clearfix has to be set every 3 div because that's that col-lg break to a new line-->

    </div>
</div>

请注意：

<div class="clearfix visible-lg-block">
</div>.

你也可以看看 flexbox。也许这会对你有所帮助，它将引导程序与 flexbox 结合起来。 http://www.bootply.com/zoupRVbLG4

我创建了这个基于 javascript 的解决方案。
小提琴：http://jsfiddle.net/mavent/zobhpkvz/7/

// html

<div class="row modify_parent">
    <div class="col-sm-4 alert alert-success modify_child">Some thing happens here..
        <br>Some thing happens here..
        <br>Some thing happens here..
        <br>Some thing happens here..
        <br>Some thing happens here..
        <br>
    </div>
    <div class="col-sm-offset-2 col-sm-4 alert alert-success modify_child">Other thing happens here..
        <br>
    </div>
</div>

// javascript

var sameHeightTop = $(".modify_parent");
if (sameHeightTop.length !== 0) {
    sameHeightTop.each(function () {
        var tallest = 0;
        var sameHeightChildren = $(this).find(".modify_child");
        sameHeightChildren.each(function () {
            var thisHeight = $(this).height();
            if (thisHeight > tallest) {
                tallest = thisHeight;
            }
        });
        sameHeightChildren.height(tallest);
    });
}
