单击链接时，如何将负margin-bottom动态应用于元素。尝试在单击选项卡时删除其底部边框。当我将负边距应用于tab元素时，它是有效的，但它应用于所有的选项卡，这看起来很有趣。有人能看一下吗？
jQuery(document).ready(function() {
jQuery('.tabs .tab-links a').on('click', function(e) {
var currentAttrValue = jQuery(this).attr('href');
// Show/Hide Tabs
jQuery('.tabs ' + currentAttrValue).show().siblings().hide();
// Change/remove current tab to active
jQuery(this).parent('li').addClass('active').siblings().removeClass('active');
// tried adding this code but it doesn't seem to work
$(function() {
$('tab-links a').click(function () {
$( ".tab-links.active" ).css('margin-bottom','-2px');
});
});
e.preventDefault();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"> </script>
</body>尝试使用toggleClass，如下所示：
JS:
$( ".tab-links a" ).click(function() {
$( this ).toggleClass( "neq-margin" );
});
CSS：
.neq-margin {
margin-bottom: -2px;
}
