修复了主要内容和幻灯片菜单在多级推送菜单上的重叠

标签: css html5 css3 drop-down-menu responsive-design

我在响应式网站上使用此菜单。

https://tympanus.net/codrops/2013/08/13/multi-level-push-menu/

这很好用,除了我无法改变将主内容推向右边的行为。我想修复主要内容,而菜单应该与主要内容重叠。

我尝试了很多东西,但不知道如何实现这一目标。任何帮助表示赞赏。

您必须更改component.css和mlpushmenu.js文件:

在component.css中:

搜索:

.mp-menu {
    position: absolute; /* we can't use fixed here :( */
    top: 0;
    left: 0;
    z-index: 1;
    width: 300px;
    height: 100%;
    -webkit-transform: translate3d(-100%, 0, 0);
    -moz-transform: translate3d(-100%, 0, 0);
    transform: translate3d(-100%, 0, 0);
}

并改变:

.mp-menu {
    position: absolute; /* we can't use fixed here :( */
    top: 0;
    left: 0;
    z-index: 1;
    width: 300px;
    height: 100%;
    -webkit-transform: translate3d(-100%, 0, 0);
    -moz-transform: translate3d(-100%, 0, 0);
    transform: translate3d(-100%, 0, 0);
    transition: all .5s;
}

现在改变mlpushmenu.js:
