当滚动页面时,我的粘滞条为什么不消失并且颜色不变,所以我找不到。
我尝试通过chrome控制台理解,但是我对JS的了解真的很差。我尝试从此处使用和转换教程:“ https://www.w3schools.com/howto/howto_js_navbar_sticky.asp”。
在野生动物园中,导航栏正在跳跃,并且不会随着滚动和IE淡出,我认为它也不会淡出(我不记得我无法在Mac上对其进行测试)
您可以在以下链接上查看该网站:http://www.coramp.eu
在模拟器上,您可以看到最高利润,但是我在任何浏览器上都没有,而且我也不想。我想将导航栏粘贴在窗口顶部
请问我可以帮忙吗? :'(
答案 0 :(得分:0)
并非所有IE版本都支持Sticky,请参阅:https://caniuse.com/#search=sticky
在野生动物园中,导航栏正在跳跃并且不会消失
在Safari上不褪色,因为您使用RGBA(将不透明度指定为0.9),但是您放置了RGB。因此,应该改为rgb(139, 139, 157, 0.9)
,rgba(139, 139, 157, 0.9);
是这样:
#header.isSticky {
background: rgba(139, 139, 157, 0.9);
...
}
跳跃是因为当您的header
变成sticky
时,它的行为类似于位置fixed
,并且下面的所有内容都“跳转”到该位置,因为它可用。一种解决方法是在您的.slideshow-container
上添加填充,然后将其放置在header
的后面,并使用负边距。
.slideshow-container {
...
padding-top: 120px; /* 50px plus header height */
margin-top: -70px; /* header height */
}
这对您有意义吗?
