列
我有一个由3列体组成的页面。在第一列和第三列内有按钮。我试着正确定位它们。
特别是，我的第一列按钮有问题，必须显示在页面底部（靠近页脚）。
但我使用的样式没有效果。我想这是因为列是空的并且定位相对于它的高度起作用。我试图使用height:100%;属性，但它不起作用。
我应该如何解决这个问题？

所以现在我的解决方案只有在我在第一列中放入大量文本时才有效 - 然后Up按钮就在它的底部附近。但没有文字它会向上发展..
编辑：我设法通过将两个按钮直接放入正文来解决它，但是如果有一个解决方案允许它们保留在各自的列中，我想知道。
{{3} }
在图片上，向上按钮位于页脚旁边，而向下按钮靠近页眉。
编辑：提出解决方案的代码：

<div class="col-md-8">.This book must have been revolutionary when it came out in the 1930s. The language, the style, the unbashed uncaring for literary norms must have been like a fresh air of rebellion to the stifled people of the 1930s who just few decades ago were under the moral oppression of the Victorian age. The book begins with an ode to Tanya's cunt. And it continues in the same manner. The word cunt is probably the most used word in the entire book. Today it would be called vulgar, but at the time it was revolutionary and brave. Miller describes multiple women he's had sex with while living in Paris, mostly on the money of other people, or as a vagrant and homeless on the streets. Most of the women he sleeps with are prostitutes (and he goes at length discussing the different types of prostitutes), but there is also the Jewish adulteress, the Russian princess with gonorrhea, the strange french woman to whom he gives 100 francs and then takes them out of her purse after having sex with her in her house above the room of her sick mother. Chapters of lucid description of characters (mostly Miller's friends whose money he uses, at whose houses he sleeps and whose women he has sex with) and some semblance of story lines are alternated with chapters of stream-of-consciousness monologues with prophetic statements and deep insights into life and living that usually come only after a very heavy intoxication with various substances. The book finishes in a middle of an action, just like it starts. Nothing really happens throughout and there's no sustained plot or even any novel-long characters (except the author-narrator) but it does give an entertaining and fascinating view into the life of the American emigres to Paris between the two wars in a much different way than Hemingway.

我建议的一种方法是使用flex
首先确保body，container，row和col1即使在空的时候也占据全高（检查确认）。
如果有，请将col1设为display:flex。然后，您可以轻松地使用flex子项的flex-end属性使其保持原状。
#upButton {
align-self: flex-end
}
答案 1 :(得分：1)
尝试将您的风格更改为此。输出可能是您要查找的结果。
<style>
#upButton {position:fixed; left:0px; bottom:0px;}
.col1 {height:100%;}
</style>
我将位置从绝对更改为固定，尝试读取位置的不同值... CSS Layout - The position Property
答案 2 :(得分：1)
修复 upButton ，我们可以控制它而不管它的父母如何这样我们就可以达到你的要求
ServerSocket sc=new ServerSocket(9999);
Socket s=sc.accept();
DataInputStream dos=new DataInputStream(s.getInputStream());
String msg=dos.readUTF();
System.out.println(msg);
