比如：
<div class="row" id="form_domain_container">
<label for="domain">域名:</label>
<input name="domain" value="<{$do->domain_name|escape}>" type="text" id="domain" size="35" maxlength="64" /><br />
<{include file='lib/error.tpl' error=$do->getError('domain_name')}>
</div>
在CSS中设置属性可以：
#form_domain_container input{}
但不可以：
.row input{}
