.content {
top: 25%;
left: 5%;
position: absolute;
}
The container of the h1 is positioned absolutely. The default z-index is causing it to overlap other elements which have a smaller z-index value.
Setting the z-index of the .content div and navbar may help to solve the problem.
.content {
top: 25%;
left: 5%;
position: absolute;
z-index: 10; /** something smaller than the z-index of the navbar **/
}
.navbar {
...
z-index: 20; /** something bigger than the z-index of .content **/
}
