これは本当に苛立たしい問題です...CSS3でスタイル設定されたHTML5ボタンを作成しました-このボタンはIEで（機能的に）機能しますが、Firefox（v 16.0.2）でページを開くとボタンが機能しません（例：それをクリックすることはできません-それは何もしません）。さらに奇妙なのは、テストのためだけに標準のhrefリンクを（同じページのボタンの横に）配置し、それをクリックすることさえできないことです（たとえば、何もしません）。このページは、IE9とFireFox16.0.2の両方の2つの異なるマシンでテストしました。
ボタンのHTMLコードは次のとおりです。
<p><button type="button" onClick="location.href='index.php'" class="navigationButton">Back to World Map</button>
<!-- test link -->
<a href="index.php">home</a></p>
そしてCSS：
.navigationButton {
font-family: Arial, Helvetica, sans-serif;
font-size: 18px;
color: #ffffff;
padding: 10px 20px;
background: -moz-linear-gradient(
top,
#86eb86 0%,
#013006);
background: -webkit-gradient(
linear, left top, left bottom,
from(#86eb86),
to(#013006));
background: -ms-linear-gradient(#86eb86, #013006);
background: -o-linear-gradient(#86eb86, #013006);
background: linear-gradient(#86eb86, #013006);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#86eb86', endColorstr='#013006');
-moz-border-radius: 15px;
-webkit-border-radius: 15px;
border-radius: 15px;
border: 3px solid #171717;
-moz-box-shadow:
0px 1px 3px rgba(000,000,000,0.5),
inset 0px 0px 10px rgba(087,087,087,0.7);
-webkit-box-shadow:
0px 1px 3px rgba(000,000,000,0.5),
inset 0px 0px 10px rgba(087,087,087,0.7);
box-shadow:
0px 1px 3px rgba(000,000,000,0.5),
inset 0px 0px 10px rgba(087,087,087,0.7);
text-shadow:
0px -1px 0px rgba(000,000,000,0.4),
0px 1px 0px rgba(255,255,255,0.3);
}
このボタンの実装が他の人（IEとFirefoxの両方）で機能する場合は、私に知らせてください。そうでない場合は、何か間違ったことをした場合は、説明も含めて知らせてください。
乾杯！
