I have a codeignter based site.In that i loaded the css file like this:

<link href="<?php echo base_url();?>style/style.css" rel="stylesheet" type="text/css" />

This is the content in that file:

.forgot_password {
    color:#FF0000;
    font-weight:bold;
    margin-left:95px;
    margin-top:10px;
    display:none;
}
.forgot_message {
    display:none;
    font-size:13px;
    font-weight:bold;
    color:#C4ED10;
}

.enter_password_fr {
    color: #FFFFFF;
    font-size: 20px;
    font-weight: bold;
    margin-left: 100px;
}

您是否可以向元素动态添加第二种样式来覆盖颜色？

.forgot_password_alt {color:#f00 !important;}
