推荐答案
您可以通过 -webkit-filter
和 filter
使用过滤器:过滤器对于浏览器来说相对较新,但根据以下 CanIUse 表,超过 90% 的浏览器都支持过滤器:https://caniuse.com/#feat=css-filters
You can use filters with -webkit-filter
and filter
:
Filters are relatively new to browsers but supported in over 90% of browsers according to the following CanIUse table: https://caniuse.com/#feat=css-filters
您可以将图像更改为灰度、棕褐色等(查看示例).
You can change an image to grayscale, sepia and lot more (look at the example).
因此您现在可以使用过滤器更改 PNG 文件的颜色.
body {
background-color:#03030a;
min-width: 800px;
min-height: 400px
}
img {
width:20%;
float:left;
margin:0;
}
/*Filter styles*/
.saturate { filter: saturate(3); }
.grayscale { filter: grayscale(100%); }
.contrast { filter: contrast(160%); }
.brightness { filter: brightness(0.25); }
.blur { filter: blur(3px); }
.invert { filter: invert(100%); }
.sepia { filter: sepia(100%); }
.huerotate { filter: hue-rotate(180deg); }
.rss.opacity { filter: opacity(50%); }
