HTML CSS : Best way to Create Search Bar with Magnify Button

Question

创建搜索栏的最佳方式是什么？

放大镜应位于左侧的文本框中，垂直居中对齐。我觉得这是一种凌乱的方式，我是靠空格' ，而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。不喜欢使用像素测量和空间，听说这不是一个好习惯。

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

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

Answer 1

您可以使用 display: flex和 align-items: center在 .md-form.mt-0风格。这将使所有居中的东西垂直对齐。现在，您只需要 padding-left: 25px关于输入风格。所以不会重叠。

请参阅下面的片段:

.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;
}
