Hello I have 3 flags (Italian, german, english) with the purpose to change language for the whole site in future. How can I make a border on a hover effect that could alxo work with IE ?

this is the CCS

.miniflags {
    float:right
    margin : 5px 20px;
    padding-right:10px;
}

and here the HTML

<div id="bandiere">
    <a><img src="ita.png" class="miniflags" /></a>
    <a><img src="ger.png" class="miniflags" /></a>
    <a><img src="eng.png" class="miniflags" /></a>
</div>

Thanx for help

Alex
