我在更改表单文本框中的占位符文本颜色时遇到问题。我正在使用zurb的粉底，这可能是罪魁祸首。占位符文本的默认颜色太浅。我正在Chrome中查看该页面。
这是我的代码。请问有谁知道如何在这种情况下更改占位符文本颜色？
<html>
<head>
<style>
input::placeholder { /* Chrome, Firefox, Opera, Safari 10.1+ */
color: #ff0000;
opacity: 1; /* Firefox */
}
input::-webkit-input-placeholder { /* WebKit, Blink, Edge */
color: #ff0000;
}
input:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
color: #ff0000;
opacity: 1;
}
input::-moz-placeholder { /* Mozilla Firefox 19+ */
color: #ff0000;
opacity: 1;
}
input:-ms-input-placeholder { /* Internet Explorer 10-11 */
color: #ff0000;
}
input::-ms-input-placeholder { /* Microsoft Edge */
color: #ff0000;
}

您的 CSS 可能被 ZurbFoundation CSS覆盖，因为您在加载 ZurbFoundation CSS 之前设置了自己的样式。尝试切换您使用的CSS的顺序，它应该可以工作。
像<div style="color:red">一样内联样式，使用<link>定义外部CSS或使用<style>在特异性或优先级上没有区别。
