“汉堡”风格菜单栏长度

Question

我在创建“汉堡菜单”时遇到问题，不知道如何解决它。

试图获得类似于本站的效果(Resize Browser)：http://www.sebastianbailey.co.uk/

当点击条形时，它会变成一个 X，但条形太短会造成一个奇怪的 X。

我已经把它放到codepen上查看了： http://codepen.io/sparcut/pen/xVyZNQ

这是我目前正在做的尝试并达到效果。

.mobile-open .nav-mobile {
    .mid {
        display: none;
    }
    .top {
        margin-top: 15px;
        margin-bottom: 0 !important;
        transform: rotate(45deg);
    }
    .bot {
        margin-top: 0 !important;
        transform: rotate(-45deg);
    }
}

感谢@ali-sheikhpour 将我推向正确的方向。虽然它仍然看起来有点不稳定。 Codepen 更新

由于您的菜单的宽度和高度比例与链接示例不同，您必须从顶部和左侧微妙地移动条形以达到对称效果（除了旋转）。我已经根据自己的选择更新了边距，但是您可以更改它们以设置您希望形成十字架的正确位置。

请运行sn-p：（我已经将html代码包装在一个500px的div中，以防止sn-p的关闭按钮和你的菜单受到干扰）

$(window).on("load", function() {
	$("#preload").fadeOut("fast");
});

$(document).ready(function() {
	$(".nav-mobile").click(function() {
		$(".nav-container").toggleClass("mobile-open");
	});
});
