html - input 的边框比 div 的边框更细

Question

我目前有这个输入和 div 彼此相邻:

如您所见，输入框的边框比包含搜索图标的 div 边框细得多。这是代码:

HTML

.location_input {
  width: 150px;
  height: 20px;
  float: left;
  padding-left: 3px;
  display: inline-block;
  -webkit-box-sizing: content-box;
  -moz-box-sizing: content-box;
  box-sizing: content-box;
  padding: 3px 15px;
  font: normal 16px/normal"Open Sans", sans-serif;
  -o-text-overflow: clip;
  text-overflow: clip;
  -webkit-transition: all 200ms cubic-bezier(0.42, 0, 0.58, 1);
  -moz-transition: all 200ms cubic-bezier(0.42, 0, 0.58, 1);
  -o-transition: all 200ms cubic-bezier(0.42, 0, 0.58, 1);
  transition: all 200ms cubic-bezier(0.42, 0, 0.58, 1);
  margin-left: 6px;
  position: relative;
  top: 42%;
  transform: translateY(-42%);
}

.update_location_wrapper {
  float: left;
  height: 30px;
  width: 30px;
  position: relative;
  border-left: none;
  display: inline-block;
  background-color: none;
  border-top: 1px solid #bbb;
  border-right: 1px solid #bbb;
  border-bottom: 1px solid #bbb;
  position: relative;
  top: 42%;
  transform: translateY(-42%);
}

<input type='text' class='location_input' placeholder='Enter a location' id='location_input'>
<div class='update_location_wrapper'>
  <div class='update_location_text'>
    <img src="//i.imgur.com/0p5bSIO.png" alt="Search" height="20" width="20">
  </div>
</div>

有没有办法让div的边框匹配输入边框？

由于输入边框在不同浏览器上看起来有些不同，您可以添加带边框的包装器，或者您可以这样做，增加输入的右侧填充并将搜索按钮移到其中。

.location_input {
  width: 150px;
  height: 20px;
  float: left;
  padding-left: 3px;
  display: inline-block;
  box-sizing: content-box;
  padding: 3px 35px 3px 15px;
  font: normal 16px/normal "Open Sans", sans-serif;
  margin-left: 6px;
  position: relative;
}

.update_location_wrapper{
  margin-top: 4px;
  margin-left: -25px;
  float: left;
  height: 30px;
  width: 30px;
  border-left: none;
  display: inline-block;
  position: relative;
}

<input type='text' class='location_input' placeholder='Enter a location' id='location_input'>
<div class='update_location_wrapper'>
  <div class='update_location_text'><img src="http://placehold.it/20x20" alt="Search" height="20" width="20"></div>
</div>
