It would make much more sense to clear this up and give the a a clear class which indicates it's semantical meaning inside the HTML:

清除它并给出一个清晰的类来表明它在HTML中的语义含义会更有意义:

Then add style:

然后添加样式:

a.whatever-fits {
    text-decoration: none;
}

Additional remarks:

Your nesting of a , h4 and span are invalid HTML.

嵌套a,h4和span是无效的HTML。

font-color:FFFFFF; has 2 mistakes:

字体颜色:FFFFFF;有2个错误:

1. there is no attribute called font-color, to style the color of text, you simply use color

   没有名为font-color的属性,为了设置文本的颜色,你只需使用颜色

2. hex colors need a leading #, e.g. #FFFFFF

   十六进制颜色需要一个前导#,例如#FFFFFF
