css - 输入内的响应式 fa-icon

Question

这是来自 Treehouse 作者的一些代码，展示了如何在输入框内放置一个图标。

HTML:

<div class="search">
  <span class="fa fa-search"></span>
  <input placeholder="Search term">
</div>

CSS:

@import url("//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css");
body {
  margin: 30px;
}

.search {
  position: relative;
  color: #aaa;
  font-size: 16px;
}

.search input {
  width: 250px;
  height: 32px;
  background: #fcfcfc;
  border: 1px solid #aaa;
  border-radius: 5px;
  box-shadow: 0 0 3px #ccc, 0 10px 15px #ebebeb inset;
}

.search input {
  text-indent: 32px;
}

.search .fa-search {
  position: absolute;
  top: 10px;
  left: 10px;
}

如何将图标放在输入的末尾并让它响应屏幕的变化？

我尝试使用百分比定位图标，但它根本不起作用。这是我尝试的 fiddle :

Answer 1

您可以将display:inline-block; 和position:relative 赋给.search 然后将图标对齐到右侧(右:10px).

Jsfiddle

@import url("//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css");
 body {
  margin: 30px;
}
.search {
  position: relative;
  color: #aaa;
  font-size: 16px;
  display: inline-block;
}
.search input {
  width: 250px;
  height: 32px;
  background: #fcfcfc;
  border: 1px solid #aaa;
  border-radius: 5px;
  box-shadow: 0 0 3px #ccc, 0 10px 15px #ebebeb inset;
}
.search input {
  text-indent: 5px;
  padding-right: 30px;
  box-sizing: border-box;
}
.search .fa-search {
  position: absolute;
  top: 8px;
  right: 10px;
}

<div class="search">
  <span class="fa fa-search"></span>
  <input type="text">
</div>
