一、易被忽略的属性
- color: currentColor
- color: window
看完之后感觉眼前一亮，有的我之前根本没有用过，甚至都不知道有color: currentColor这么个东西，抑制不住内心的好奇立马翻阅资料看了看以上属性的区别。接下来小编就谈谈本人学习之后的理解
1、color: currentColor
currentColor关键字的使用值是color属性值的计算值。如果currentColor关键字被应用在 color 属性自身，则相当于是 color: inherit；
div { border: 1px solid; color: red; }
上述代码将会让div拥有一个红色的边框，这就解释了 border-color 属性的默认值是color属性的值；如果将上述代码中的color属性定义删除，那么边框的颜色将取决于父元素的 color 计算值，因为 color 拥有继承性；
如果父级元素也没有指定颜色，那它的父级元素就会从父级的父级去继承，直到文档的根结点html标签都还没显示指定一个颜色呢，就用浏览器默认的颜色，例如：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
.mm{
color:currentColor;
}
</style>
</head>
<body>
<div class="box">
<div class="mm">sdfsdfsdf</div>
</div>
</body>
</html>
看到这里currentColor的作用大概已经了解了，接下来看看currentColor可以怎么用，先看其兼容性，主流浏览器都兼容，IE9以上
用于渐变、用于svg、用于动画等，下面以渐变为例：
<div class="box"></div>
.box{
height:100px;
color: #3CAADB;
background-image: linear-gradient(to right, #fff, currentColor 100%);
}
效果如图所示：
2、color: window
.mm{
padding: 10px;line-height: 30px;display: inline-block;color:window;background-color: red
}
系统默认设置文本颜色：
（无）也就是白色
效果如下：
如图所示color:window取得是系统默认的颜色，该颜色是根据系统默认设置文本颜色的改变而改变的
结束语：不知不觉已经工作了一年多了，这一年来从一名什么都不知道的小白，变成一名稍微知道一点皮毛的小白，想想也真是心酸。看着技术大牛们时不时的分享一些自己学 习的经验，我只能各种顶礼膜拜。今天鼓起勇气跳出来分享一些平时工作中遇到的问题和总结，内心还是十分忐忑不安的...第一次写文章写的不好望各位大神轻拍，写的不对的不好的可以留言指出，或者加本人QQ群519875573，希望大家共同交流进步
