导航栏中标题阻止链接中的图像

Question

我的导航栏中间有一个图像阻止了我的链接，我在下面做了一些代码来表明这一点。我尝试用z-index修复此问题，但它一直阻止我的链接 由于我的其余代码（不在此代码段中），我无法将图像放在导航栏中。我认为如果我得到<a>背后的绝对图像应该可以解决，但我无法用z-index＆＃39;

$(document).ready(function () {
        $("nav a").click(function(event){
        $("article").removeClass("slide_1");
        $("article").removeClass("slide_2");
        $("article").removeClass("slide_3");
            var clickedId = event.target.id;
            $('article').addClass("slide_"+clickedId);
        });
    });

将z-index:-1提交至z-index: 1;，将z-index:1; position:relative;提交至nav。

＆＃13;

＆＃13;

$(document).ready(function () {
        $("nav a").click(function(event){
        $("article").removeClass("slide_1");
        $("article").removeClass("slide_2");
        $("article").removeClass("slide_3");
            var clickedId = event.target.id;
            $('article').addClass("slide_"+clickedId);
        });
    });
