如何将此搜索框的位置更改为右上角并对齐？

HTML

<form class="form-wrapper cf">
  <input type="text" placeholder="Search here..." required>
  <button type="submit">Go</button>
</form>

CSS

.cf:before, .cf:after{
    content:"";
    display:table;
}
.cf:after{
    clear:both;
}
.cf{
    zoom:1;
}

  1. 关闭按钮标签

  2. 您已经浮动了搜索栏和按钮。在插入样式为“clear:both”的 div 之前，父 div 不会使用子元素占据的高度。您在表格之后做了“明确：两者”，而不是在孩子之后。

    <form class="form-wrapper cf">       
    <input type="text" placeholder="Search here..." required>  
    <button type="submit">Go< /button>< div style="clear:both">  
    </div>  
</form>

关于右上对齐，您需要将其定位为绝对或固定，并指定“右”和“上”属性。你甚至尝试过这样做吗？或者，您是否认为您可以从某个地方复制一个片段，而 Stackoverflow 成员会为您修复它？

.form-wrapper {
    width: 450px;
    padding: 15px;
    position: absolute;
    top:50px;
    right: 50px;
    background: #444;
    background: rgba(0,0,0,.2);
    border-radius: 10px;
    box-shadow: 0 1px 1px rgba(0,0,0,.4) inset, 0 1px 0 rgba(255,255,255,.2);
}

这是固定代码 - http://jsfiddle.net/a2ev8/2/
