网页的 Material 设计。如何设置 mdc.menu 的位置？
我会将 mdc 菜单从左上角移动到右上角。顶部 70 像素，右侧 25 像素。
请看我的截图。
如何更改元素样式。
请看一下我的js代码。我必须在哪里进行更改？在 css 中还是在 javascript 中？下面的更改是我使用浏览器 chrome 完成的。
element.style {
right: 25px;
top: 70px;
}
这是完整的html代码。

const drawer = mdc.drawer.MDCDrawer.attachTo(document.querySelector('.mdc-drawer'));
const topAppBar = mdc.topAppBar.MDCTopAppBar.attachTo(document.querySelector('#app-bar'));
topAppBar.listen('MDCTopAppBar:nav', () => {
drawer.open = !drawer.open;
});
const menu = mdc.menu.MDCMenu.attachTo(document.querySelector('.mdc-menu'));
menu.setAnchorCorner(mdc.menu.Corner.BOTTOM_LEFT);
menu.open = false;
menu.setFixedPosition(true);
const btn = document.querySelector('#menu-button');

最佳答案
可以设置mdc-menu的位置使用属性方法的组件setAbsolutePosition()它有两个参数；第一个:是从顶部开始的位置，作为整数，第二个作为水平位置，作为 n 个整数。
例子:yourElement.setAbsoltuePosition(100,100)
这将设置 yourElement 的位置距离顶部 100 像素，距离左侧 100 像素。
