将图片与 div 完美地并排放置

Question

如何在不同的屏幕尺寸下完美地放置图片？

.background-login {
  background: url(../img/login.png) no-repeat;
  background-size: 100%;
  z-index: -2;
  position: absolute;
  top: 8%;
  min-height: 400px;
  right: 2%;
  height: 100%;
}

.background-login-create {
  background: url(../img/login.png) no-repeat;
  background-size: 100%;
  z-index: -2;
  position: absolute;
  top: 17%;
  min-height: 400px;
  right: 2%;
  height: 100%;
}

.background-login-create-profile {
  background: url(../img/login.png) no-repeat;
  background-size: 100%;
  z-index: -2;
  position: absolute;
  top: 13%;
  min-height: 400px;
  right: 2%;
  height: 100%;
}

.sellfie-start-text {
  font-size: 15px;
  padding: 145px;
  text-align: center;
  font-weight: 200;
  position: relative;
  top: 8%;
  vertical-align: middle;
  color: #FFF;
}

<div class="container div-login">
  <div class="row">
    <div class="col-sm-5 col-md-offset-1">
      <div class="center">
        <h2 class="login-title"></h2>

      </div>
    </div>
    <div class="col-sm-6 background-login">
      <div class="sellfie-logo">
        <img src="img/sellfie_white.png"/>
      </div>    
      <div class="sellfie-start-text">

        and online channels.
      </div>    
    </div>  
  </div>
</div>

如果左侧容器更大，我希望右侧的图像与左侧容器具有相同的高度，该怎么办？

   .background-login {
    background: url(../img/login.png) no-repeat;
    background-size: cover;
    z-index: -2;
    position: absolute;
    margin-top: 50px;
    right: 2%;
    min-height:400px;
    height: 100%;

}

你需要这样的东西吗：链接如下：https://css-tricks.com/perfect-full-page-background-image/ - Razia sultana

我制作了这个简单的 fiddle，它使用相对和绝对定位。您的容器应该是相对的，左右内容应该是绝对的。尝试在我的 fiddle 中更改 wrapper 的宽度和高度，您会发现内容也会随之改变。有用的示例。 - Roy123

我很困惑为什么这里需要任何绝对的东西？ - Tom

Answer 1

我已经在background-login元素中添加了wrapper，并添加了一些CSS使其居中对齐。

在.background-login的CSS中，设置background-size: cover（这将使图像覆盖整个元素）。

我还删除了top和right值，在Bootstrap列上不要设置位置值，因为它们会破坏布局。

body {
  background-color: #ddd !important;
}

.form-left,
.background-login {
  height: 400px;
}

.form-left {
  background-color: white;
}

.background-login {
  position: relative;
  background: url(https://unsplash.it/600/400) no-repeat;
  background-position: center center;
  background-size: cover;
}

.background-login .wrapper {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  padding: 30px;
  text-align: center;
}

.sellfie-start-text {
  font-size: 15px;
  text-align: center;
  font-weight: 200;
  position: relative;
  top: 8%;
  vertical-align: middle;
  color: #FFF;
}
