html - 如何将按钮右对齐？

Question

下午好， 我意识到这个话题已经被问过好几次，并且有几个解决方案，正如我在搜索你们的论坛时看到的那样。

但是解决方案，例如， <input type="button" value="Click Me" **style="float: right;"**> ,

即使按钮成功地向右对齐，它们也会与我的页脚重叠，因为按钮应该位于页脚的正上方。这是我的代码:

.button {
  border-radius: 4px;
  background-color: #0FA0FF;
  border: none;
  color: #FFFFFF;
  text-align: center;
  font-size: 15px;
  padding: 10px;
  width: 200px;
  transition: all 0.5s;
  cursor: pointer;
  margin: 5px;
}
.button span {
  cursor: pointer;
  display: inline-block;
  position: relative;
  transition: 0.5s;
}
.button span:after {
  content: '\00bb';
  position: absolute;
  opacity: 0;
  top: 0;
  right: -20px;
  transition: 0.5s;
}
.button:hover span {
  padding-right: 25px;
}
.button:hover span:after {
  opacity: 1;
  right: 0;
}
.containers-fluid {
  padding: 20px 50px;
  background-color: #000000;
  color: white;
}

<button class="button"><span>Proceed to Next Lesson </span>
</button>

<footer class="containers-fluid text-center">
</footer>

Answer 1

只需将样式 float:right 添加到您的 button

在 button 和 footer 之间添加这个

<div class="clearfix"></div>

和 clearfix 的 css

.clearfix{
 clear: both;
}
