这里我的代码正在工作。但汉堡菜单不可见。这里。菜单换行。菜单这个选择器导致了问题。加入这个汉堡后就看不见了。如何设计才能让我看到汉堡菜单并点击。有办法做到这一点吗。如果需要，我可以加载图像进行理解。

</html>在css中，您可以在其中设置汉堡菜单的样式：
.menu-wrap .hamburger {
position: absolute;
top: 0;
left: 0;
z-index: 1;
width: 60px;
height: 60px;
padding: 1rem;
background: var(--primary-color);
display: flex;
align-items: center;
justify-content: center;
}
您希望它与屏幕的右上角对齐，所以只需将left: 0;替换为right: 0;即可。
