所以我使用混合混合模式：乘法；悬停时在我的图像上创建多层的效果。问题是图层超出了图像边界，如下图所示。我尝试将宽度和高度设置为 .imgcon 和 .imgcon > img（请参见下面的代码），并且该图层适合，但是当在不同的屏幕分辨率上查看时，它会弄乱响应式 Web 功能。所以我尝试将宽度和高度设置为 100% 以保持响应功能，但图层仍然超出图像边框。

如您所见，多层从图像中渗出

这是我的代码：

.imgwrapper {
  position: relative;
}



.imgcon + div {
 position: absolute;
  left: 42%;
  top: 44%;
  color: white;
  text-decoration: underline;
  opacity:0;
  display: block;
  pointer-events: none;
  font-size: 18px;
  
  letter-spacing: 4px;

}

.imgcon {
 position: relative;
 background: rgba(209, 19, 15, 0);
  transition: ease 0s;
  -webkit-transition: ease 0s;
  -moz-transition: ease 0s;
  -ms-transition: ease 0s;
  -o-transition: ease 0s;
   mix-blend-mode: multiply;
}
.imgcon > img {
 transition: ease 0s;
  -webkit-transition: ease 0s;
  -moz-transition: ease 0s;
  -ms-transition: ease 0s;
  -o-transition: ease 0s;
}
.imgcon:hover {
  background: #b41f24;
    background: rgba(180, 31, 36, 0.85);


}
.imgcon:hover > img {
  z-index: -1;
  -webkit-filter: grayscale(100%) blur(1.5px) contrast(100%);
  filter: grayscale(100%) blur(1.5px) contrast(100%) ;
  mix-blend-mode: multiply;

}

.imgcon:hover + div {
  display: block;
  opacity: 1;
  z-index: 1;
}
<a href="works.html?option=emkoinvite" class="permalink">
					<div class="desktop-3 mobile-half columns">
						<div class="item first-row">
							<h3>EmKO invitation</h3>
							<span class="category">Identity, print</span>

							<div class="imgwrapper">
							<div class="imgcon">
							<img src="http://i.imgur.com/XmhcxJS.png" /></div>
							<div id="view">view</div></div>
						</div><!-- // .item -->
					</div><!-- // .desktop-3 -->
				</a>

Here's your solution. For an explanation, any block element is by default going to be 100% the width of its parent. If you want the element to remain the widths of its container, you need to use a different display attribute; inline-block seemed to make the most sense here.

The added space at the bottom is something that many elements have, I call it the descender space. Certain letters like "g" and j" dip below the text line. The parts that dip are called descenders. Many elements leave a little room for descenders. To get rid of this space, you can set line-height to 0.

The width and centered text stuff was just an easier way for me to center the text properly.

Let me know if you have any other issues!

.imgwrapper {
  position: relative;
}



.imgcon + div {
 position: absolute;
  text-align: center;
  top: 42%;
  width: 256px;
  color: white;
  text-decoration: underline;
  opacity:0;
  display: block;
  pointer-events: none;
  font-size: 18px;
  
  letter-spacing: 4px;

}

.imgcon {
 position: relative;
 display: inline-block;
 line-height: 0;
 background: rgba(209, 19, 15, 0);
  transition: ease 0s;
  -webkit-transition: ease 0s;
  -moz-transition: ease 0s;
  -ms-transition: ease 0s;
  -o-transition: ease 0s;
   mix-blend-mode: multiply;
}
.imgcon > img {
 transition: ease 0s;
  -webkit-transition: ease 0s;
  -moz-transition: ease 0s;
  -ms-transition: ease 0s;
  -o-transition: ease 0s;
}
.imgcon:hover {
  background: #b41f24;
    background: rgba(180, 31, 36, 0.85);


}
.imgcon:hover > img {
  z-index: -1;
  -webkit-filter: grayscale(100%) blur(1.5px) contrast(100%);
  filter: grayscale(100%) blur(1.5px) contrast(100%) ;
  mix-blend-mode: multiply;

}

.imgcon:hover + div {
  display: block;
  opacity: 1;
  z-index: 1;
}
<a href="works.html?option=emkoinvite" class="permalink">
					<div class="desktop-3 mobile-half columns">
						<div class="item first-row">
							<h3>EmKO invitation</h3>
							<span class="category">Identity, print</span>

							<div class="imgwrapper">
							<div class="imgcon">

							<div id="view">view</div></div>

您所缺少的只是display: inline-block;图像的父级上的一个：

.imgwrapper {
  position: relative;
}
.imgcon + div {
 position: absolute;
  left: 42%;
  top: 44%;
  color: white;
  text-decoration: underline;
  opacity:0;
  display: block;
  pointer-events: none;
  font-size: 18px;
  letter-spacing: 4px;
}
.imgcon {
 display: inline-block;
 position: relative;
 background: rgba(209, 19, 15, 0);
  transition: ease 0s;
  -webkit-transition: ease 0s;
  -moz-transition: ease 0s;
  -ms-transition: ease 0s;
  -o-transition: ease 0s;
   mix-blend-mode: multiply;
}
.imgcon > img {
 transition: ease 0s;
  -webkit-transition: ease 0s;
  -moz-transition: ease 0s;
  -ms-transition: ease 0s;
  -o-transition: ease 0s;
}
.imgcon:hover {
  background: #b41f24;
  background: rgba(180, 31, 36, 0.85);
}
.imgcon:hover > img {
  z-index: -1;
  -webkit-filter: grayscale(100%) blur(1.5px) contrast(100%);
  filter: grayscale(100%) blur(1.5px) contrast(100%) ;
  mix-blend-mode: multiply;
}
.imgcon:hover + div {
  display: block;
  opacity: 1;
  z-index: 1;
}
<a href="works.html?option=emkoinvite" class="permalink">
					<div class="desktop-3 mobile-half columns">
						<div class="item first-row">
							<h3>EmKO invitation</h3>
							<span class="category">Identity, print</span>
							<div class="imgwrapper">
							<div class="imgcon">
							<img src="http://i.imgur.com/XmhcxJS.png" /></div>
							<div id="view">view</div></div>
						</div><!-- // .item -->
					</div><!-- // .desktop-3 -->
				</a>

那是因为该父级是一个 div，因此它是一个块元素并占用所有可用宽度。更改它display以inline-block使其包装到它的孩子的尺寸。
