这是我用html代码的css
.sub-nav { display: none; }
input[type=checkbox]:checked + label ~ .sub-nav { display: inline; }<html>
<body>
<input type="checkbox" name="lingue" value="ing" id="ing"><label for="ing">Inglese</label> 
<select class="sub-nav">
<option value="ott">Ottimo</option>
<option value="buo">Buono</option>
<option value="suff">Sufficente</option>
<option value="scol">Scolastico</option>
<option value="pess">Pessimo</option>
</select>
<br>
<input type="checkbox" name="lingue" value="ted" id="ted"><label for="ted">Tedesco</label> 
<select class="sub-nav">

<option value="buo">Buono</option>
<option value="suff">Sufficente</option>

<input type="checkbox" …如何通过仅向客户端提供 IP 地址的网络部分来在 LAN 上找到 Java 服务器？我可以这样做吗？
