👉

1. CSS 过滤器: 亮度

    filter: brightness(0.4);

2. CSS 过滤器: 灰度

    filter: grayscale(1);

3. CSS 过滤器: 透明度

    filter: opacity(0.3);

4. CSS 过滤器: 模糊

    filter: blur(2px);

5. CSS 过滤器: 反转

    filter: invert(1);

6. clip-path

使用 clippy 可以轻松生成想要的 clip-path

    clip-path: polygon(
  50% 0%, 61% 35%,
  98% 35%, 68% 57%,
  79% 91%, 50% 70%,
  21% 91%, 32% 57%,
  2% 35%, 39% 35%
);

7. mix-blend-mode

首先创建一个文字，使它位于图片 img 之上:

    <div style="position: relative">
  <img src="sample.png"/>
  <span style="
    position: absolute;
    top: 50%;left: 50%;
    transform: translate(-50%, -50%);">
    LISA
  </span>
</div>

LISA

然后设置 mix-blend-mode:

    .span {
  mix-blend-mode: screen;
}

LISA

8. 水墨效果

    .ink-effect {
  background-image: url(/sample.png);
  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;
}

9. 铅笔效果

    .pencil-effect {
  background-image: url(/sample.png), url(/sample.png);
  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;
}

10. 彩色铅笔效果

    .colored-pencil-effect {
  position: relative;
  background-image: url(/sample.png);
  box-shadow: inset 0 0 0 1px black;
  background-size: contain;
}
.colored-pencil-effect:before, .colored-pencil-effect:after {
  display: block;
  content: "";
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-size: cover;
  box-shadow: inset 0 0 0 1px black;
}
.colored-pencil-effect:before {
  background-image: url(/sample.png), url(/sample.png);
  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);
}
