CSS 验证错误 : Same colors for color and background-color in two contexts

标签 css

我需要帮助来解决验证 CSS。 在这里，我在 W3 验证中遇到了 20 个相同的错误。我不明白。 如果您能解决此问题，我将不胜感激。

错误: 两种上下文中 color 和 background-color 的颜色相同

这是供您审阅的 CSS 代码:

最佳答案

好吧，CSS 验证器会向您显示错误/警告在哪一行，所以这已经是一个开始。

现在要做什么(例子)

Same colors for color and background-color in two contexts .caseStudy-table ul li.boldtext and a:hover

意思是:

您的背景颜色与文本颜色相同。验证器显示警告，因为可能无法阅读文本。 (有没有试过在白色背景上阅读白色文本？)

.caseStudy-table ul li.boldtext {
    background-color : #29a1d6; /* background-color */
    color : #ffffff;
    font-weight : bold;
}

a:hover {
    color : #29a1d6; /* text color */
}

如果您在 .caseStudy-table ul li.boldtext 中没有链接，那没关系。这就是为什么消息是警告而不是错误的原因。
