您遇到此问题的原因是您有以下 CSS(在 style.css 的第 273 行附近):
.menu-toggle:hover,
button:hover,
input[type="submit"]:hover,
input[type="button"]:hover,
input[type="reset"]:hover,
article.post-password-required input[type=submit]:hover {
color: #5e5e5e;
background-color: #ebebeb;
background-repeat: repeat-x;
background-image: -moz-linear-gradient(top, #f9f9f9, #ebebeb);
background-image: -ms-linear-gradient(top, #f9f9f9, #ebebeb);
background-image: -webkit-linear-gradient(top, #f9f9f9, #ebebeb);
background-image: -o-linear-gradient(top, #f9f9f9, #ebebeb);
background-image: linear-gradient(top, #f9f9f9, #ebebeb);
}
只需将其删除,一切都会按您的预期工作。
OP的补充 - 上述答案
将引导样式表中的以下行标记为重要
background-image: -moz-linear-gradient(top, #0088cc, #0044cc) !important;
background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#0088cc), to(#0044cc)) !important;
background-image: -webkit-linear-gradient(top, #0088cc, #0044cc) !important;
background-image: -o-linear-gradient(top, #0088cc, #0044cc) !important;
background-image: linear-gradient(to bottom, #0088cc, #0044cc) !important;
