Question

我试图创建一个灵活的导航栏，在较小的屏幕上有一个下拉菜单。我的基础是https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_topnav

下拉菜单在较小的屏幕上中断。我上面有图标。所以不是＆＃34; Home Home＆＃34;它有一个房子图标，而不是第一个带有标题的房屋。

＆＃13;

//  FUNCTION FOR NAV BAR  //
function myfunction() {
  var topNavX = document.getElementById("myTopnav");
  if (topNavX.className === "topnav") {
    topNavX.className += "responsive";
  } else {
    topNavX.className = "topnav";
  }
}

追加额外的课程

topNavX.className + =“responsive”;

在附加新的类名之前应该有一个间距。
