I am working on a project which requires both Bootstrap & Materialize frameworks. I have this navbar toggle which is normal when not in active state.
But when it goes into active state and has a background fill with the default colors of Materialize CSS.
I am trying to set the background color to transparent but it doesn't. This is the CSS which I tried.
.navbar-toggler-icon{
background-color: transparent !important;
}
.navbar-toggler-icon :active{
background-color: transparent !important;
}
This is the codepen link.
