Question

我试图让徽标响应并在小屏幕和大屏幕上保持相同的比例。但是，在笔记本电脑上，徽标在全分辨率下太大，但在较小的屏幕上接近正确的尺寸。任何有关如何修复图像大小的帮助表示赞赏。哦，请不要告诉我使用bootstrap或任何框架！

/* Toggle between adding and removing the "responsive" class to topnav when the user clicks on the icon */
function myFunction() {
  var x = document.getElementById("myTopnav");
  if (x.className === "topnav") {
    x.className += " responsive";
  } else {
    x.className = "topnav";
  }
}

Answer 2

从图像显然太大的事实来看，我首先要在任何图像编辑软件中调整图像大小

<img id="logo" src="">

CSS：

#logo {
width: %; //whatever percentage you find most appropriate 
}

但请记住，宽度取决于父容器（100％是父容器的宽度）。

在您的情况下，父母是＆＃34; ul＆＃34;它占据了宽度的100％，因此徽标占据了宽度的35％。
