我有一个 jquery 幻灯片，在纵向和横向位置都有两种不同的图像尺寸。我设法将它们水平居中，但无法让它们垂直居中。
我尝试在 #slideshow { 中使用垂直对齐，但它没有用。我尝试指定一个“顶部”像素位置以使横向图像居中，但纵向图像未居中。有人可以帮忙吗？我已经包含了下面的代码。谢谢！
function slideSwitch() {
var $active = $('#slideshow DIV.active');
if ( $active.length == 0 ) $active = $('#slideshow DIV:last');
// use this to pull the divs in the order they appear in the markup
var $next = $active.next().length ? $active.next()
: $('#slideshow DIV:first');
// uncomment below to pull the divs randomly
// var $sibs = $active.siblings();
// var rndNum = Math.floor(Math.random() * $sibs.length );
// var $next = $( $sibs[ rndNum ] );
$active.addClass('last-active');
$next.css({opacity: 0.0})
.addClass('active')
.animate({opacity: 1.0}, 300, function() {
$active.removeClass('active last-active');
});
}
var intervalID = "";
$(function() {
intervalID = setInterval( "slideSwitch()", 5000 );
});
</script>
