我曾多次使用float:右(或左)将图像和嵌入框浮动在容器顶部。现在,我需要浮动一个div到另一个div的右下角与正常的文本包装,你得到的浮动(文本包装上面和左边只有)。

我认为这一定是相对容易的,即使浮动没有底部值,但我还没有能够做到这一点使用一些技术和搜索网络还没有出现任何其他使用绝对定位,但这并没有给出正确的换行行为。

我原以为这是一种很常见的设计,但显然不是。如果没有人有建议,我将不得不把我的文本分解成单独的盒子,并手动对齐div,但这是相当不稳定的,我不想在每个需要它的页面上都这样做。

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;
}

将div放在另一个div中,并设置父div的样式为position:relative;然后在子div上设置以下CSS属性:位置:绝对;底部:0;

浮动和绝对定位的组合对我来说很有用。我试图把消息的发送时间放在语音气泡的右下角。时间不应该与消息体重叠,除非真的有必要,否则它不会使气泡膨胀。

解决方案是这样的:

有两个跨度,文本完全相同; 一个漂浮着,但看不见; 另一个是绝对定位到角落;

不可见的浮动对象的目的是保证可见对象的空间。

.speech-bubble { font-size: 16px; max-width: 240px; margin: 10px; display: inline-block; background-color: #ccc; border-radius: 5px; padding: 5px; position: relative; } .inline-time { float: right; padding-left: 10px; color: red; } .giant-text { font-size: 36px; } .tremendous-giant-text { font-size: 72px; } .absolute-time { position: absolute; color: green; right: 5px; bottom: 5px; } .hidden { visibility: hidden; } <ul> <li> <span class='speech-bubble'> This text is supposed to wrap the time &lt;span&gt; which always seats at the corner of this bubble. <span class='inline-time'>13:55</span> </span> </li> <li> <span class='speech-bubble'> Absolute positioning doesn't work because it doesn't care if the two pieces of text overlap.

随着Flexbox的引入,这变得非常容易,不需要太多的黑客。align-self:子元素的flex-end将沿着交叉轴对齐。

.container {
  display: flex;
}
.bottom {
  align-self: flex-end;
}
<div class="container">
  <div class="bottom">Bottom of the container</div>
</div>

输出:

.container { 显示:flex; /*材质设计阴影*/ Box-shadow: 0 2px 2px 0 rgba(0,0,0,0.14), 0 3px 1px -2px rgba(0,0,0,0.2), 0 1px 5px 0 rgba(0,0,0,0.12); 身高:100 px; 宽度:175 px; 填充:10 px; 背景:# fff; 字体类型:Roboto; } .bottom { align-self: flex-end; } < div class = "容器" > <div class="bottom">容器底部</div> < / div >

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。

另一种解决方案是明智地使用表和行span。通过设置前一行的所有表格单元格(除了主要内容外)为rowspan="2",您将始终在您的主表格单元格的底部获得一个单元格孔,您可以始终放置valign="bottom"。

您还可以将其高度设置为一行所需的最小值。这样,不管剩下的文本占据了多少空间,你总是会在底部看到你最喜欢的一行文本。

我尝试了所有的div答案,我无法让他们做我需要的。
