Question

创建搜索栏的最佳方法是什么？

放大镜应在左侧文本框内，垂直居中对齐。我觉得这是一种混乱的方式，我依靠空格，并且放大镜不是垂直对齐的。可以使用顶部像素边距，但似乎有一种更清洁的方法。刚开始学习html和CSS。听说这不是一个好习惯，不喜欢使用像素测量和空间。

.md-form.mt-0{
  display:inline-flex;
  width:500px;
}

.material-icons.mdc-button__icon{
  position:absolute;
  top:7px;
  left: 2px;
 
}

<link href="https://fonts.googleapis.com/icon?family=Material+Icons"
      rel="stylesheet">
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

Answer 1

您可以使用display: flex风格的align-items: center和.md-form.mt-0。这将使居中的所有内容垂直对齐。现在，您只需要padding-left: 25px的输入样式即可。因此不会重叠。

请参见下面的代码段

.md-form.mt-0{
  width:500px;
  display:flex;
  align-items: center;  
}

.material-icons.mdc-button__icon{
  position:absolute;
}

.mdc-button__icon + input{
  padding-left: 25px;
}

Answer 2

您可以使用Bootstrap的默认.input-group（https://getbootstrap.com/docs/4.3/components/input-group/）

如果输入的背景色困扰您，则可以根据需要进行调整。

此外，如果您愿意，也可以尝试摆脱分隔它们的边界，但我认为这是不必要的。

请参见下面的演示代码

.input-group .input-group-text {
  background-color: #fff;
}

/* if you wish */
.input-group input.form-control{
  border-left-color: #FFF;
}

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text" id="basic-addon1">
       <i class="material-icons mdc-button__icon">search</i>
    </span>
  </div>
  <input type="text" class="form-control" placeholder="Search" aria-label="Search" aria-describedby="basic-addon1">
</div>

这是我的解决方案。仅HTML和CSS。放大镜是可免费使用的自举SVG。运行代码片段以查看结果。

.svgWrapper{
  position:absolute;
  top:21px;
  left:15px;
}

.searchBox{
  text-indent:30px;
  margin-top:10px;
  width:200px
}

<html>
      <div class="search">
        <div class="svgWrapper">
          <svg class="bi bi-search" width="1em" height="1em" viewBox="0 0 16 16"               fill="currentColor" xmlns="http://www.w3.org/2000/svg">
               <path fill-rule="evenodd" d="M10.442 10.442a1 1 0 011.415 0l3.85                 3.85a1 1 0 01-1.414 1.415l-3.85-3.85a1 1 0 010-1.415z" clip-                     rule="evenodd"/>
               <path fill-rule="evenodd" d="M6.5 12a5.5 5.5 0 100-11 5.5 5.5 0                  000 11zM13 6.5a6.5 6.5 0 11-13 0 6.5 6.5 0 0113 0z" clip-                        rule="evenodd"/>
           </svg>
        </div>
      <input class='searchBox'type="search" placeholder="Search the web"results="0" />
    </div>
</html>
