CodePudding user response：
In the first code, Remove overflow property from the navbar, and add a min-height to it like this,
.topnav {
/* overflow: hidden; */
background-color: #333;
position: sticky;
top: 0;
min-height: 45px;
}
Since you are using the float property in navigation items, it may cause trouble
The working code Code
CodePudding user response：
I have corrected your code because the overflow hidden dropdown menu was not visible checkout this code. If you want then I can paste the full code here. I hope this will help you.
Your first code solution
.topnav {
background-color: #333;
position: sticky;
top: 0;
}
@media screen and (min-width:768px){
.topnav {
display: flex;
}
}
@media screen and (max-width: 767.98px){
.topnav {
overflow: hidden;
}
}
Your second code solution
ul {
display: flex;
list-style-type: none;
margin: 0;
padding: 0;
/* overflow: hidden; */
background-color: #333;
position: -webkit-sticky; /* Safari */
position: sticky;
top: 0;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
/* overflow: hidden; */
background-color: #38444d;
}
