到目前为止，Stu的答案是最接近工作的，但它仍然没有考虑到外部div的高度可能会根据文本在其中的换行方式而改变的事实。因此，只重新定位内部div(通过改变“pipe”的高度)一次是不够的。这种改变必须发生在循环内部，因此您可以不断检查是否已经达到了正确的定位，并在需要时进行重新调整。

前面答案中的CSS仍然完全有效:

#outer {
    position: relative; 
}

#inner {
    float:right;
    position:absolute;
    bottom:0;
    right:0;
    clear:right
}

.pipe {
    width:0px; 
    float:right

}

然而，Javascript应该看起来更像这样:

var innerBottom;
var totalHeight;
var hadToReduce = false;
var i = 0;
jQuery("#inner").css("position","static");
while(true) {

    // Prevent endless loop
    i++;
    if (i > 5000) { break; }

    totalHeight = jQuery('#outer').outerHeight();
    innerBottom = jQuery("#inner").position().top + jQuery("#inner").outerHeight();
    if (innerBottom < totalHeight) {
        if (hadToReduce !== true) { 
            jQuery(".pipe").css('height', '' + (jQuery(".pipe").height() + 1) + 'px');
        } else { break; }
    } else if (innerBottom > totalHeight) {
        jQuery(".pipe").css('height', '' + (jQuery(".pipe").height() - 1) + 'px');
        hadToReduce = true;
    } else { break; }
}

在与各种技巧斗争了几天之后，我不得不说这似乎是不可能的。即使使用javascript(我不想这样做)，这似乎是不可能的。

To clarify for those who may not have understood - this is what I am looking for: in publishing it is quite common to layout an inset (picture, table, figure, etc.) so that its bottom lines up with the bottom of the last line of text of a block (or page) with text flowing around the inset in a natural manner above and to the right or left depending on which side of the page the inset is on. In html/css it is trivial to use the float style to line up the top of an inset with the top of a block but to my surprise it appears impossible to line up the bottom of the text and inset despite it being a common layout task.

我想我将不得不重新审视这个项目的设计目标，除非有人有最后的建议。

If you're okay with only the bottom-most line of the text going to the side of the block (as opposed to completely around and underneath it, which you can't do without ending the block and starting a new one), it's not impossible to float a block to one of the bottom corners of a parent block. If you put some content in a paragraph tag within a block and want to float a link to the bottom right corner of the block, put the link within the paragraph block and set it to float: right, then put in a div tag with clear: both set just underneath the end of the paragraph tag. The last div is to make sure the parent tag surrounds the floated tags.

<div class="article" style="display: block;">
    <h3>title</h3>
        <p>
            text content
            <a href="#" style="display: block;float: right;">Read More</a>
        </p>
    <div style="clear: both;"></div>
</div>

很长一段时间以来，我也一直在寻找这个解决方案。 这是我得到的结果:

align-self: flex-end;

您可以尝试使用宽度为1px的空元素并将其浮动。然后清除您实际想要定位的元素，并使用空元素的高度来控制它向下移动的距离。

.invisible {
float: left;  
}

.bottom {
float: left;
padding-right: 35px;
padding-top: 30px;
clear: left;
}

设置父div为position: relative，然后内部div为…

position: absolute; 
bottom: 0;

.．.就这样了。
