Greetings!
Just starting my day here and see your post notification.One thing though, is it possible to get a link to your site where this is? But let’s see if I can help here with colours based on the theme’s own demo site for reference.
For the first one about links, this is the theme’s default link colour:
a,
a:visited {
color: #59a9bb;
}
a:focus,
a:hover {
color: #161616;
}
So to override that, copy the ones you want to change and put it into the Additional CSS tab of the customizer. Hopefully that helps.
For the main menu current colour, this is the batch of code that does this to the menu link(s).
@media (min-width: 992px) {
.main-navigation-menu a:focus,
.main-navigation-menu a:hover,
.main-navigation-menu li.home a:focus,
.main-navigation-menu li.home a:hover,
.main-navigation-menu li.current-menu-item > a,
.main-navigation-menu li.current-menu-item.menu-item-home a:focus,
.main-navigation-menu li.current-menu-item.menu-item-home a:hover {
color: #4a9fb3;
}
}
Copy that code also, then just change the color: value.
For the button, this is the theme’s default colouring for buttons:
.button, button,
input[type="submit"],
input[type="reset"],
#infinite-handle span,
.wp-block-button .wp-block-button__link {
background-color: #bcd6dc;
color: #fff;
}
Once again, copy that and then update the colours. However, if you want to just change the button you mentioned, you can do it like this:
input[type="submit"] {
background-color: #bcd6dc;
color: #fff;
}
That will change all form buttons that are using the button type “submit”. Usually this will be any form that has a submit button.
Hopefull all the above helps ??
