我在使用bootstrap词缀时遇到了问题,并且停留了两天,因此我需要您的重要帮助。
我是网络开发人员的新手,请原谅我的转储问题。我玩着有关词缀(粘性导航栏)的w3schools示例
就我而言,我想将导航栏保持在屏幕底部,并且在用户滚动时,我希望导航栏变得粘稠。
我已经尝试了百万种方法来避免导航栏跳动,但是没有成功。
当我尝试在容器流体类中设置高度:vh时出现问题。我试图设置没有运气的百分比。
由于我请求您的帮助,我认为我的方法不正确。
欢迎任何建议:)

答案 0 :(得分:1)
您可以使用粘性位置。像这样:
.affix {
top: 0;
position: sticky;
width: 100%;
z-index: 9999 !important;
}
