粘性標題轉換不順利

Question

我創建了一個粘性標題。其中我也調整了徽標圖像的大小。 這工作正常。我只是想當徽標圖像被調整到更小和更大的尺寸時發脾氣。

我可以得到任何幫助。

     window.addEventListener('scroll', function(e) { 
     var distanceY = window.pageYOffset || document.documentElement.scrollTop, 
      shrinkOn = 300, 
      header = document.querySelector(".header-top"); 
     if (distanceY > shrinkOn) { 
      classie.add(header, "smaller"); 
     } else { 
      if (classie.has(header, "smaller")) { 
      classie.remove(header, "smaller");

Answer 1

div.header-top img#logo { 
display: inline-block; 
height: 150px; 
width:200px; 
float: left; 
font-size: 60px; 
color: white; 
-webkit-transition: all 0.3s; 
-moz-transition: all 0.3s; 
-ms-transition: all 0.3s; 
-o-transition: all 0.3s; 
transition: all 0.3s; } 

給一個寬度圖像和你的小圖像

div.header-top.smaller img#logo { 
    font-size: 30px; 
    height: 100px; 
line-height: 75px; 
width: 125px; 
-webkit-transition: all 0.3s; 
-moz-transition: all 0.3s; 
-ms-transition: all 0.3s; 
-o-transition: all 0.3s; 
transition: all 0.3s; }
