请教个CSS，给图标加框框

/*Greasemonkey*/
#greasemonkey-tbb >* {
    padding:4px 4px !important;
    border:1px solid #BBC2C8 !important;
    margin-left:-5px !important;
    list-style-image:url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAA6klEQVR42qWTMQrCQBBFF7xEgrUklWDhBSIWSeMBrDyIJNewES+wYGMv6BnEE0SsxNiJEv/CrIzDZg268CCT+f9nYCdKNZwkSTpgAlbgACqwVW0OhCNwBLVgBjIw9Jmn4OEwc+YuYw9ocP9ivhitNEfUqFtitJE1p+DMmhsQgDFN8yRNCNZMZzypCShFesgmW4AlqwOhLZUcj4Q7YgD6tqbep74h4P0sa1dA+UfASdFiSIMZee+pbUDm+kLuWbLcNaF5cbU3AArP/RfsJm48QPMd8EzQJY3Rat6If9jE2LXOmn7bJmNFmsj6XniZHU4PnwhMAAAAAElFTkSuQmCC")!important;

}


这么写不对吗？然后现在点他也不能出来菜单了

我想弄成这样的

#greasemonkey-tbb image {
padding:5px 4px !important;
border:1px solid #DCDCDC !important;
margin-left:-8px !important;
}
加框框这样就足够了。

n2day：#greasemonkey-tbb image {
padding:5px 4px !important;
border:1px solid #DCDCDC !important;
margin-left:-8px !importan...回到原帖
