帮忙修改下css代码，使得两组div可以inline_html/css_WEB-ITnose
css div html
要疯了，在改进别人的一个系统，用的css代码是原来就有的。。我在表单里新增了5个select选项，每个select都有一个label，一起放在一个div中，所有共有5个div。现在想让这5组div分两行显示，第一行三个，第二行两个。如果让我自己写倒是没有问题，问题是原本css中就有了这个表单的样式，现在要在原本的基础上改，结果改了半天，还是没有成功。。。要疯了已经！！
下面把我的表单和css贴出来，麻烦大家帮忙看一下修改一下，每次都在这上面花最多时间，我讨厌层叠样式表！！！！！
<html><link rel="stylesheet" href="css/mrbs.css.php" type="text/css"> <link rel="stylesheet" media="print" href="css/mrbs-print.css.php" type="text/css"> <form id="add_room" class="form_admin" action="addsystem.php" method="post"> <fieldset> <legend>Add System</legend> <div id="sdw-div" style="white-space:nowrap; display:inline"> <label for = "sdw">sdw:</label> <select id="sdw" name="sdw" style="display:inline"> <option selected="selected" value="0">0</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> </select></div> <div id="etl-div" style="white-space:nowrap; display:inline"> <label for = "etl">etl:</label> <select id="etl" style="display:inline" name = "etl"> <option selected="selected" value="0">0</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> </select></div><div id="hdm-div" style="white-space:nowrap; display:inline"> <label for = "hdm">hdm:</label> <select id="hdm" style="display:inline" name = "hdm"> <option selected="selected" value="0">0</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> </select></div>.........以此类推，还有两个不贴了</form></html>
css 文件中关于表单form_admin的设置如下 (select设置是我新加的，因为选项也是我后来加的）
form.form_admin {float: left; clear: left; margin: 2em 0 0 0}.form_admin fieldset {float: left; width: auto; border: 1px solid <?php echo $admin_table_border_color ?>; padding: 1em}.form_admin legend {font-size: small}.form_admin div {float:left; clear:left;}.form_admin label { display: block; float: left; clear: left; width: <?php echo $admin_form_label_width ?>em; min-height: 2.0em; text-align: right;}.form_admin input { display: block; float: left; clear: right; width: <?php echo $admin_form_input_width ?>em; margin-top: -0.2em; margin-left: <?php echo $admin_form_gap ?>em; font-family: <?php echo $standard_font_family ?>; font-size: small;}.form_admin select { display: block; float: left; clear:right; margin-left: 1.0em;}.form_admin input.submit { width: auto; margin-top: 1.2em; margin-left: <?php echo number_format(($admin_form_gap + $admin_form_label_width), 1, '.', '')?>em}回复讨论(解决方案)
现在弄好了没？
回楼上，好了，因为每个select都有一个div框架，所以只要设置div的format
在css文件中，把form_admin div {float:left; clear:left} 中的clear:left 去掉，
然后新加了一个div class：
div.div_break {clear:left}
然后在admin page中，每个需要独占一行的select 设置如下:
如果需要和上一个select输出在同一行，则不需要 class="div_break" 这一属性
