如何在搜索输入中放置和居中显示图像并使其在移动设备上看起来很好？

Question

我正在尝试创建与Google搜索类似的搜索主页。我用css完成了大部分工作，但如果我不在图像和输入之间使用<br>标记，我就会遇到问题。

<div class="page">

<img class="logo" src="https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png">

<input id="searchme" class="search" title="Search" type="text"><br>
    <div class="Bcontainer">
      <div class="button left">Search</div>
      <div class="button right">Check Blog</div>
    </div>
</div>

Css是......

body {
    font-size: 13px;
    width: 100%;
    margin: 0;
    padding: 0;
}

.page {
  padding-top: 20vh;
  text-align: center;
  padding-bottom: 20px;
  margin-bottom: 25vh;
}

.logo {
  padding-bottom: 15px;
}

.search {
  width: 30vw;
  padding: 15px;
  border: 1px solid #d9d9d9;

这是尝试居中图像和输入的小提琴...... https://jsfiddle.net/rm36nfgL/

这是完整的页面示例... https://jsfiddle.net/sh7zy9re/

那么，两个问题......

1. 如何放置图像并在另一个下面输入并居中。
2. 使用哪种@media状态，是电话视图的@media only screen and (max-width: 959px)，以及css中要更改的内容，因此（图像作为徽标和输入）看起来大约是手机上整页宽度的90％？

Answer 1

我想你只需要添加：

.page {
  //...
  display: flex;
  flex-direction: column;
  align-items: center;
}

Answer 2

图像和输入是内联块元素。要获得正确的流量，请在它们上使用显示块：

div {
  border: 1px solid red;
  padding: 5px 10px;
  margin: 5px;
}

.block img, .block input {
  display: block;
}

<div>
  <h3>Without display block</h3>
  <img class="logo" src="https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png">
  <input type="text">
</div>
<div class="block">
  <h3>With display block</h3>
  <img class="logo" src="https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png">
  <input type="text">
</div>

Answer 3

请检查.search {}上的css代码。你把宽度设置为30vw，我不知道什么是vw意味着，只需将其改为300px，然后你的代码结果看起来很整洁。

    .search {
      width: 300px;
      padding: 15px;
      border: 1px solid #d9d9d9;
      background: url(data:image/png;base64,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) no-repeat;
