html - 部分图像覆盖在响应式 View 中

Question

我有一个使用 CSS 掩码创建的图像动画，但出于某种原因，我的媒体查询的 max-width: 100%; 属性在 img 上隐藏/覆盖图像的一部分。如果我删除它，它会正常显示，但随后图像没有响应。

可在此处找到代码/演示(调整结果窗口大小以重现):http://jsfiddle.net/x2hnomhs/ .

如有任何帮助，我们将不胜感激。谢谢!

将 height:auto 更改为 height:100% @media screen and (max-width: 940px)

片段:

.logo {
  display: block;
  width: 450px;
  margin: 0 auto;
  padding-bottom: 40px;
}
.logo a {
  display: block;
  height: 288px;
  overflow: hidden;
  width: 450px;
  position: relative;
}
.logo a img.logoMask {
  position: relative;
  z-index: 20;
  width: 100%;
  height: auto;
}
.logo a img.color {
  position: absolute;
  z-index: 1;
  left: 0;
  top: 3px;
  -webkit-animation: logoColor 15s infinite; /* Chrome, Safari, Opera */
  animation: logoColor 15s infinite;
}

/* Chrome, Safari, Opera */
@-webkit-keyframes logoColor {
  0% {
    left: 0;
  }
  50% {
    left: -2500px;
  }
  100% {
    left: 0;
  }
}
/* Standard syntax */
@keyframes logoColor {
  0% {
    left: 0;
  }
  50% {
    left: -2500px;
  }
  100% {
    left: 0;
  }
}
@media screen and (max-width: 940px) {
  img {
    max-width: 100%;
    height: 100%;
  }
}

<div class="logo">
  <a style="padding-right: 0">
    <img src="http://api.marioparra.me/img/api-logo-mask.png" class="logoMask" />
    <img src="http://api.marioparra.me/img/api-logo-gradient.png" class="color" />
  </a>

</div>

更新:基于 OP 评论(阐明 OP 真正想要实现的目标)

由于您想在所有视口(viewport)尺寸中制作相同类型的动画并使其响应，这里是一个片段(添加了注释以解释更改):

.logo {
  display: block;
  max-width: 450px;
  /* changed from width to max-width */
  margin: 0 auto;
  padding-bottom: 40px;
  overflow: hidden;
  /* added this */
}
.logo a {
  display: block;
  height: 288px;
  overflow: hidden;
  max-width: 450px;
  /* changed from width to max-width */
  position: relative;
}
.logo a img.logoMask {
  position: relative;
  z-index: 20;
  width: 100%;
  height: auto;
}
.logo a img.color {
  position: absolute;
  z-index: 1;
  left: 0;
  top: -50%;
  /* changed from 3px to -50% */
  -webkit-animation: logoColor 5s infinite;
  /* Chrome, Safari, Opera */
  animation: logoColor 5s infinite;
}
/* Chrome, Safari, Opera */

@-webkit-keyframes logoColor {
  0% {
    left: 0;
  }
  50% {
    left: -2500px;
  }
  100% {
    left: 0;
  }
}
/* Standard syntax */

@keyframes logoColor {
  0% {
    left: 0;
  }
  50% {
    left: -2500px;
  }
  100% {
    left: 0;
  }
}
/*removed uncessary media queries because you are using now max-width in your parent container , with that your img {width:100%} it is enough to make it responsive. */

@media screen and (max-width: 480px) {
  .logo a img.color {
    top: -60%
  }
}
@media screen and (max-width: 360px) {
  .logo a img.color {
    top: -72%
  }
}

<div class="logo">
  <a style="padding-right: 0">
    <img src="http://api.marioparra.me/img/api-logo-mask.png" class="logoMask" />
    <img src="http://api.marioparra.me/img/api-logo-gradient.png" class="color" />
  </a>
</div>
