我有这样的代码:
<div class="lighter">
<form method="get" action="http://www.google.pl" id="search">
<span>
<input id="button_search" type="image" src="images/search.png" id="button_search"/>
</span>
<span>
<input type="text" class="search rounded" placeholder="Search...">
</span>
<div class= "list_search">
<ul>
<li class="search_link"><a href="">Search all of Movies</a></li>
<li class="search_link"><a href="">Advanced Search</a></li>
</ul>
</div>
</form>
</div>
是否可以简单地使用 css 来产生当 input type="text" 处于焦点时 list_search 会出现的效果?如果是,如何?
非常感谢您的帮助
