I have been asked to theme my APEX 19.2 app and the designer has come back with a fairly simple ask. The top left hamburger be white and purple like below:
I am using the theme roller to apply the settings and can't seem to get the active and inactive state to stay white and purple.
I have even tried my own CSS in the theme roller like below but only with limited success. Any ideas how I can achieve this?
CSS I am currently trying
t-Button--icon {
color: #393093!important;
background: #ffffff!important;
border-color: #393093!important;
}
t-Button--header {
color: #393093!important;
background: #ffffff!important;
border-color: #393093!important;
}
t-Button--headerTree {
color: #393093!important;
background: #ffffff!important;
border-color: #393093!important;
}
t-Header-controls {
color: #393093!important;
background: #ffffff!important;
border-color: #393093!important;
}
is-active {
color: #393093!important;
background: #ffffff!important;
border-color: #393093!important;
}
NavigationBar {
color: #393093!important;
background: #ffffff!important;
border-color: #393093!important;
}
Even with all of this my button active and hover still looks like this:
I feel like I am close but after several hours of fiddling, I thought it was about time I consult the collective experts. Any help and advice would be greatly appreciated. If you can't already tell I am still learning CSS.
