这代码有点不懂

<div class="inputs">

            <div class="sign-input"><span>帐　号：</span><span><input autocomplete="on" name="u" id="u" type="text" style="ime-mode: disabled" class="input01" tabindex="1" value="QQ号码或Email帐号" onFocus="if (value =='QQ号码或Email帐号'){value =''}" onBlur="if (value ==''){value='QQ号码或Email帐号';}" /></span></div>

            <div class="sign-input"><span>密　码：</span><span><input name="p" id="p" maxlength="16" type="password" class="input01" tabindex="2" /></span></div>

        </div>

两个都是class=“input01” 

而样式是这样的 .inputs.sign-input input{...}
