我制作了一个名为#work的{{1}}。内部#work是名为div的另一个.item。问题是我想让div #work做出回应。我已经尝试了一切来实现我的目标，但都是徒劳的。我的代码如下：
HTML：
<div id="work"> <!-- Work Links Section Start -->
<div class="item">
<a href="air-ticket.php"><img src="images/work/thumbs/air.jpg" alt="Air Ticket"></a><!-- Image must be 400px by 300px -->
<h3>Air Ticketing</h3><!--Title-->
<!--Category-->
</div><!--/item-->
<div class="item">
<a href="hotelbook.php"><img src="images/work/thumbs/hotelbook.jpg" alt="Hotel Booking"></a><!-- Image must be 400px by 300px -->
<h3>Hotel Booking</h3><!--Title-->
<!--Category-->
</div><!--/item-->
CSS：

.item{
