Website
我想要一个带有php的函数来改变特定div的边界，具体取决于我所在的网站
示例：点击新闻 - ＆gt; page：？page = news - ＆gt; div#news {border-bottom: 4px solid orange;}。现在我只需要实现最后一部分，我已经休息了。我尝试使用这个功能：
<?php
function chosen_page ($page) {
echo '<style type="text/css">
#header_navbar div $page {
border-bottom: 4px solid #F0641D;
}';
}
?>
body {
margin: 0;
padding: 0;
background-color: #F0641D;
background-image: url("data/RLbackground.jpg");
background-repeat: no-repeat;
background-attachment: fixed;
background-position: center 0;
font-family: "Trebuchet MS", sans-serif;
color: #c4c4c4;
}
a {
color: #F0641D;
text-decoration: none;
transition: color 0.5s linear;
}
#impressum {
background-color: #383838;
width: 1000px;
margin: 16px auto;
padding: 8px 0;
text-align: center;
text-decoration: underline;
}
#heading {
font-weight: bold;
letter-spacing: 2px;
font-size: 20px;
}
#header {
width: 100%;
height: 64px;
background-color: #383838;
position: fixed;
margin-top: -80px;
}
#header_content {
width: 1000px;
margin: 0 auto;
}
#header_navbar div {
float: none;
display: inline-block;
margin-right: -5px;
border-bottom: 4px solid #505050;
transition: border-bottom 0.5s linear, background-color 0.5s linear;
}
#header_navbar div a {
display: block;
font-size: 25px;
padding: 15.5px 23px;
}
#header_navbar div:hover {
border-bottom: 4px solid #F0641D;
background-color: #505050;
}
#header_navbar div:hover a {
color: #383838}
#layout {
width: 976px;
margin: 80px auto 16px auto;
padding: 12px;
background-color: #383838;
overflow: hidden;
}
#layout_left {
float: left;
width: 684px;
margin: 0 16px -16px 0;
}
#content_left {
padding: 4px 8px;
margin-bottom: 16px;
box-shadow: 0 0 8px #F0641D;
}
#layout_right {
float: right;
width: 276px;
margin-bottom: -16px;
}
#content_right {
margin-bottom: 16px;
padding: 4px 8px;
box-shadow: 0 0 8px #F0641D;
}
#twitter_timeline {
margin-bottom: 16px;
box-shadow: 0 0 8px #F0641D;
height: 700px;
border-radius: 4px;
overflow-y: auto;
