我是“编程”网站的新手(只是为了好玩),遇到了一个我找不到解决方案的问题。
代码末尾或打开代码/ Tisire / pen / wLRvdR
菜单按钮应该固定并且永远不会隐藏 但是向下滚动时,菜单按钮位于弹性框后面
我已经在这里发现了类似的问题,但是对我来说却没有可行的解决方案……弯曲和位置似乎不是一个很好的组合。
有人知道吗?
代码:
function openNav() {
document.getElementById("myNav").style.height = "100%";
}
function closeNav() {
document.getElementById("myNav").style.height = "0%";
}
/* Menu */
#topnav {

padding-right: 1em;

padding-top: 0.5em;
}
#menubutton {
font-size:80px;
cursor:pointer;

}
#menuright {

padding-right:5em;
}

只需将z-index属性添加到您的按钮
function openNav() {
document.getElementById("myNav").style.height = "100%";
}
function closeNav() {
document.getElementById("myNav").style.height = "0%";
}
/* Menu */
#topnav {

float:left;
padding-top: 0.5em;
}
#menubutton {
font-size:80px;
cursor:pointer;
z-index:3;
position:fixed;
}
#menuright {
float: right;
