Link 仍然带有下划线，即使 text-decoration 设置为 none

Question

我在这个网站上看到了几个相关的问题，但它们似乎都是由选择器问题引起的，但我认为这不是这里的问题。
在我的例子中，Google Chrome 和 Safari 都告诉我相关 a 标签的计算样式有 text-decoration:none.
选择 a 标签并设置 text-decoration:none 没有区别，因为它们已经有 text-decoration:none.
该页面的样式来自几个不同的样式表，其中一个来自我的博客主题，一个来自 namespaced import 的 Materialize 框架，最后一个是我留下空的用户定义样式表（因此我没有在这个 post 中包含 CSS）。

Answer 1

那里不是文字装饰。这是一个背景图像。 Chrome 开发工具显示：

a {
    color: #0076df;
    background-image: linear-gradient(to top, transparent 13%, rgba(0, 118, 223, 0.8) 13%, rgba(0, 118, 223, 0.8) 18%, transparent 17%);
    text-shadow: white 1px 0px 0px, white -1px 0px 0px;
}

当我在开发工具中禁用background-image 属性时，蓝线消失了。

Answer 2

将background-image: none;添加到.mcss a

.mcss a {
    color: #039be5;
    text-decoration: none;
    background-image: none;
}

Answer 3

好的，这可能会对你有所帮助

.mcss a:active, .mcss a:hover {background-image: none;} .mcss a {color: #039be5;background-image: none;text-decoration: none;}

Link 仍然带有下划线，即使 text-decoration 设置为 none

Link is still underlined even though text-decoration is set to none
