用CSS实现各种图片滤镜效果演示

原图：

下面大多数的效果图中，背景图片源background-image url通常会反复使用数次，同时利用CSS混合模式 (multiply, overlay, screen, difference等)进行处理。

在有一些效果中，使用了一下CSS filter 属性进一步处理图片，比如 grayscale(), brightness(), 和 contrast() 等可以让图片呈现出更好的效果。

制作这个演示时，我们首先让这些图片呈现出原始面貌，然后使用CSS @supports 来检测某种CSS属性是否在你的浏览器中受支持。

然后才施加这些效果。

效果1：Pencil

.pencil-effect {

$url : url(photo.jpg);

background-size: cover;

background-position: center;

@supports (filter: invert(1)) and (background-blend-mode: difference) {

background-blend-mode: difference;

background-position:

calc(50% - 1px) calc(50% - 1px),

calc(50% + 1px) calc(50% + 1px);

filter: brightness(2) invert(1) grayscale(1);

box-shadow: inset 0 0 0 1px black;

}

效果2：Emboss

.emboss-effect{

$url:url(photo.jpg);

background-image:$url;

background-size:cover;

background-position:center;

@supports (filter: invert(1)) and (background-blend-mode:difference, screen){

background-image:$url,$url,$url;

background-blend-mode:difference, screen;

background-position:

calc(50%-1px)calc(50%-1px),

calc(50%+1px)calc(50%+1px),

center;

filter: brightness(2) invert(1) grayscale(1);

}

效果3：Colored chalkboard

.colored-chalkboard-effect {

$url : url(photo.jpg);

background-size: cover;

background-position: center;

@supports (filter: brightness(2)) and (background-blend-mode: color, difference) {

background-size: cover;

background-position:

calc(50% - 1px) calc(50% - 1px),

calc(50% + 1px) calc(50% + 1px),

center;

background-blend-mode: color, difference;

filter: brightness(2);

}

效果4：hallucination

.hallucination-effect {

$url : url(photo.jpg);

$offset : 5px;

background-size: cover;

background-position: center;

@supports (mix-blend-mode: multiply) {

position: relative;

overflow: hidden;

background-color: magenta;

background-blend-mode: screen;

&:before, &:after {

display: block;

content: "";

position: absolute;

top: 0;

left: 0;

right: 0;

bottom: 0;

background: inherit;

mix-blend-mode: multiply;

transform: scale(1.05);

}

&:before

{ background-color: yellow;

background-blend-mode: screen;

transform-origin: top left;

}

&:after {

background-color: cyan;

background-blend-mode: screen;

transform-origin: bottom right;

}

效果5：collage

.collage-effect {

$url : url(photo.jpg);

@supports (background-blend-mode: overlay) {

background-size: 200%, 80%, 60%, 50%, 40%, 100%;

background-position: 50%, 80%, 30%, 0;

background-blend-mode: overlay;

background-repeat: no-repeat;

}

效果6：infrared

.infrared-effect {

$url : url(photo.jpg);

background-size: cover;

background-position: center;

filter: hue-rotate(180deg) saturate(2);

}

效果7：selective-color

.selective-color-effect {

$url : url(photo.jpg);

background-size: cover;

background-position: center;

@supports (filter: brightness(3)) and (mix-blend-mode: color) {

&:before, &:after {

display: block; content: "";

position: absolute;

top: 0;

left: 0;

right: 0;

left: 0;

right: 0;

bottom: 0;

background-size: cover;

box-shadow: inset 0 0 0 1px black;

}

&:before {

background-blend-mode: difference;

background-position:

calc(50% - 1px) calc(50% - 1px),

calc(50% + 1px) calc(50% + 1px);

filter: brightness(2) invert(1) grayscale(1);

}

&:after {

background: inherit;

mix-blend-mode: color;

}

效果9：photo-border
