php - 无法在 div 中将搜索栏居中

Question

我的网站标题中有一个搜索栏。它是 div 中的输入。我似乎无法弄清楚如何将搜索栏居中放置在 div 的中间。我已经在响应方面完美地设置了它，所以除了居中之外我不想改变它的定位方式。任何帮助将不胜感激。

HTML:

<form method="get" id="searchform" action="<?php bloginfo('url'); ?>">
  <div>
    <label hidden="true" for="s">Search for:</label>
    <input placeholder="I want to go see lighthouses" class="text" type="text" value="I want to go see lighthouses" name="I want to go see lighthouses" id="s" onfocus="(this.value == 'I want to go see lighthouses') && (this.value = '')" onblur="(this.value == '') && (this.value = 'I want to go see lighthouses')" />
    <input hidden="true" type="submit" class="submit" name="Submit" value="Search!" />
  </div>
</form>

CSS:

#searchform div {
  shadow: 4px 7px 4px #000000;
  position: absolute;
  width: 100%;
  bottom: 90px;
}

#searchform .text {
  font-family: 'Merriweather';
  background: white url('images/search-img.png') no-repeat;
  background-position: 96% center;
  font-size: 220%;
  color: #B7B7B7;
  border-radius: 50px;
  padding-left: 35px;
  height: 75px;
  width: 600px;
  max-width: 100%;
  display: inline-block;
  margin: 0 auto;
}

#searchform .text:focus {
  background-image: none;
}

#searchform .text img {
  margin-right: 25px;
}

将 text-align 添加到包装 div 以使内联内容居中。

   #searchform div {
     position: absolute;
     width: 100%;
     bottom: 90px;
     text-align: center/* Text align here */     
   }


   #searchform .text {
     font-family: 'Merriweather';
     background: white url('images/search-img.png') no-repeat;
     background-position: 96% center;
     font-size: 220%;
     color: #B7B7B7;
     border-radius: 50px;
     padding-left: 35px;
     height: 75px;
     width: 100%; /* Updated thiese two widths, better for your responsive design */
     max-width: 600px;
     display: inline-block;
     margin: 0 auto;
   }
   #searchform .text:focus {
     background-image: none;
   }
   #searchform .text img {
     margin-right: 25px;
   }

<form method="get" id="searchform" action="<?php bloginfo('url'); ?>">
  <div>
    <label hidden="true" for="s">Search for:</label>
    <input placeholder="I want to go see lighthouses" class="text" type="text" value="I want to go see lighthouses" name="I want to go see lighthouses" id="s" onfocus="(this.value == 'I want to go see lighthouses') && (this.value = '')" onblur="(this.value == '') && (this.value = 'I want to go see lighthouses')"
    />
    <input hidden="true" type="submit" class="submit" name="Submit" value="Search!" />
  </div>
</form>
