我正在尝试在 Royalslider 插件上添加一个徽标。它设置为 100% 宽度和灵活的宽度以适应响应式布局。我使用 css 在 Royalslider 顶部放置了一个徽标。它有效,但不完全是我想要的。我基本上计算滑块的当前高度,并将 CSS margin-top 设置为该值除以 1.5。
无论浏览器窗口的大小如何,我都希望它垂直居中。这可能吗?我的数学需要调整吗?任何想法表示赞赏。

<p id="floating-logo" class="align-center"><img src="wp-content/themes/skeleton/images/parallax_logo.png" /></p>
当前 CSS(仅适用于 p 标签):
#floating-logo {
display: block;
position: absolute;
margin: 0 auto 0 auto;
width: 100%;
z-index: 3000;
}
#floating-logo img {
margin: 0 auto 0 auto;
}
Javascript:
jQuery(document).ready(function() {
offsetHeight = jQuery("#new-royalslider-1").height();
offsetHeight = 0 - offsetHeight / 1.5;
//console.log(offsetHeight);
jQuery("p#floating-logo").css("margin-top", offsetHeight);
//console.log(jQuery("p#floating-logo").css("margin-top"));
$(window).resize(function() {
offsetHeight = jQuery("#new-royalslider-1").height();
offsetHeight = 0 - offsetHeight / 1.5;
console.log(offsetHeight);
jQuery("p#floating-logo").css("margin-top", offsetHeight);
console.log(jQuery("p#floating-logo").css("margin-top"));
})
});
