我正在尝试弄清楚如何应用悬停效果 4， http://miketricking.github.io/dist/ .
我能够在 jfiddle 上想出这个测试，https://jsfiddle.net/34aaqh70/
我也不知道如何让它自动响应。
如果有人知道解释这种效果的视频，请分享!
我的代码:
*------ Basic Setup ------*/ * {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
background-color: white;
color: #fff;
font-family: 'Raleway', 'Lato', 'Arial', sans-serif;
font-weight: normal;
font-size: 20px;
text-rendering: optimizeLegibility;
overflow-x: hidden;
}
.clearfix {
zoom: 1
}
.clearfix:after {
content: '.';
clear: both;
display: block;

visibility: hidden;
}
.row {

margin: 0 auto;
}
/*------ Dividers ------*/
.divider {

height: 30px;
border-bottom: 1px solid rgba(89, 89, 89, 0.65);
text-align: center;
margin: auto;
margin-bottom: 4%;
}
.divider span {

}
/*------ DV BOX ------*/

padding-right: 5%;
}
.donate img {

}
.donate img:hover {

}
/*------ Volunteer ------*/

看起来你的问题是你有一个固定高度/宽度的图像，它位于一个设置为 100% 的 div 中。试试下面的代码。
https://jsfiddle.net/nLd80s6f/
我将图像元素的宽度更改为 100%，并调整叠加元素的填充和边距以响应图像。我还将整个图标包裹在一个额外的 div(类“wrapper”)中并将宽度设置为 80%。这只是为了让图标更接近您的原始大小。如果您在开发工具中将其关闭，您就会明白我添加它的原因。
要使此图标完全响应，您需要添加媒体查询以在断点处缩小字体。如果您对如何做到这一点有疑问，欢迎您提问:)
