Question

这可能是一个愚蠢的问题，但我的背景颜色具有高对比度，我希望我的<ul>的{{1}}根据背景颜色为每个人 <li>。我真的不想通过向每个人添加<li>属性来膨胀我的CSS。如果有任何办法，请有人告诉我。

我正在开发一个CodePen项目。这是一个个人投资组合页面。仅供参考，我将与您分享，但尚未完成。我希望我的技能下的列表是“颜色响应”（如果它甚至存在），以便底部的项目更容易阅读。

Here is the pen.

非常感谢！

Answer 1

只需使用CSS，您就可以mix-blend-mode使用ul。

将css到ul元素作为mix-blend-mode: difference;

Answer 2

mix-blend-mode属性定义元素的内容应如何与其背景混合。这意味着任何图像或文本，边框或标题都将受此属性的影响。

见here。参考：Pen

＆＃13;

var modeList = [
  "normal",
  "multiply",
  "screen",
  "overlay",
  "darken",
  "lighten",
  "color-dodge",
  "color-burn",
  "hard-light",
  "soft-light",
  "difference",
  "exclusion",
  "hue",
  "saturation",
  "color",
  "luminosity"
],
  elem = document.querySelector(".box"),
  propertyName = "mix-blend-mode",
  modeElem = document.querySelector(".mode-name"),
  duration = 2500;

var i = 0;
var activate = setInterval(function() {
  if (i == modeList.length) i = 0;
  var mode = modeList[i];
  elem.style.mixBlendMode = mode;
  modeElem.innerText = mode;
  i++;
}, duration);
