PHP变量中加CSS代码。解决方法

<br />#scrolling_1 { width:635px; height:240px; overflow:hidden; padding:1px; border:1px solid #999; margin:0 auto; text-align: left; }<br />#scrollnews_1 { position:absolute; width:645px; height:240px; overflow:hidden; display:inline; top:1; left:1; }<br />#scrollnews_con_1 { width:645px; overflow:hidden; }<br />#scrolling_1 ul { display:block; height:240px; width:645px; }<br />#scrolling_1 ul li { height: 240px; width: 205px; float: left; overflow:hidden; display: inline; margin-right: 10px; }<br />这个我想给PHP变量付值后输出。<br /><?<br />for (i=0 ;i=100; i++) {<br />echo "#scrolling_1 { width:635px; height:240px; overflow:hidden; padding:1px; border:1px solid #999; margin:0 auto; text-align: left; }";<br />#scrollnews_1 { position:absolute; width:645px; height:240px; overflow:hidden; display:inline; top:1; left:1; }<br />#scrollnews_con_1 { width:645px; overflow:hidden; }<br />#scrolling_1 ul { display:block; height:240px; width:645px; }<br />#scrolling_1 ul li { height: 240px; width: 205px; float: left; overflow:hidden; display: inline; margin-right: 10px; }<br /><br />}<br />?><br />这么写了以后，不正常了。<br />我该怎么写呢？<br /><br />
