# 具体遇到的问题

问题1. 为什么在.banner .banner-form form{}中设置color: #808080, 没有产生继承效果，在input或者textarea中输入的字体还是黑色。必须在单独在.banner .banner-form form input {} 和.banner .banner-form form textarea {}中设置才生效。

问题2. 为什么在.banner .banner-form form p input{}中，在不设置background：none情况下，设置 color: #808080 对于<input type="button" value=“xxxx“>中的value字体颜色不生效；

.banner .banner-form form {

color: #808080;

}
