css - 悬停时按钮颜色不变

Question

我希望悬停时按钮中的链接颜色为黄色，但它似乎不起作用，因为悬停时文本仍然是白色。

html:

<button class="headerbutton headerbutton-style">
     <a href="#">Learn More</a>
</button>

CSS:

a, .headerbutton {
    -webkit-transition: all 0.2s ease-in; 
    -moz-transition: all 0.2s ease-in;
    -o-transition: all 0.2s ease-in; 
}

.headerbutton {
    font-family: "Open Sans";
    font-weight: 400;
    font-size: 12pt;
    border-radius: 20px;
    cursor: pointer;
    padding: 15px 25px;
}

.headerbutton-style {
    background-color: #FAD059;
    border: 2px solid white;
}

.headerbutton-style:hover {
    background-color: white;
    color: #FAD05A;
}

.headerbutton a {
    color: white;
    text-decoration: none;
}

.headerbutton a:hover {
    color: #FAD05A;
    text-decoration: none;
}

Answer 1

改变这个规则

.headerbutton a:hover {
    color: #FAD05A;
    text-decoration: none;
}

对此

.headerbutton:hover a {
    color: #FAD05A;
    text-decoration: none;
}

然后它就可以工作了。看这个http://codepen.io/anon/pen/RaLwEB
