【问题描述】：
我正在将我的网站部署到生产环境并运行 Lighthouse 审计。运行审计时审计抛出错误。它告诉我“373px 的视口大小与 360px 的窗口大小不匹配”。我已经验证了我的 HTML 和 CSS，但没有发现具体的错误。我不确定它是否在我的侧导航栏的 .style.width 中。
Javascript：
function openNav() {
document.getElementById("mySidenav").style.width = "150px";
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
}
function openNav2() {
document.getElementById("mySidenav2").style.width = "150px";
}
function closeNav2() {
document.getElementById("mySidenav2").style.width = "0";
}
function openNav3() {
document.getElementById("mySidenav3").style.width = "150px";
}
function closeNav3() {
document.getElementById("mySidenav3").style.width = "0";
}

检查您的浏览器缩放比例是否为 100%，并确保 DevTools 未停靠在单独的窗口中。这些是首先要尝试的两件事，因为原则上 HTML 和 CSS 看起来不错（即使我将它复制到小提琴中，我也无法判断它们是否会影响某些布局方式）。
-
谢谢，您知道移动页面的尺寸应该是多少吗？不应该超过 360px 吗？
-
移动页面可以任意大，这完全取决于您的网站内容。有些人在平板电脑上一直使用他们的“移动布局”来横向（例如 1024 像素），其他人有 2 个断点用于小手机屏幕（

@PythonCoder1981 这里有更新吗？我看到的是如果我在桌面菜单上使用水平弹性框，我总是会收到这个错误。如果我使用 old skool CSS box 模型，没有 Lighthouse 会失败。如果我使用
display:none;隐藏 flexbox 桌面菜单将起作用，但只有在返回时使用display:inherit;。
