我有一个由3列体组成的页面。第一列和第三列内有按钮。我试图正确定位它们。列内绝对位置
特别是，我有一个问题，必须显示在页面底部（靠近页脚）的第一列的按钮。
但我用的样式没有效果。我想这是因为列是空的，并且定位是相对于其高度而言的。我试图使用height:100%;属性，但它不起作用。
我该如何解决它？

所以现在我的解决办法只能如果我把大量文字的第一列里 - 然后向上按钮靠近页脚，因为它应该是。但没有文字它向上...
编辑：我设法解决它通过把两个按钮正确的身体，但如果有一个解决方案，允许他们留在各自的专栏，我想知道。 
在图片上，向上按钮靠近页脚，而向下按钮靠近页眉。
编辑：有建议的解决方案代码：

<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.
