I am amateur to the wordpress. I found this theme (sparkling) and I very like it. I have problem that I don’t know how to put slider with pictures under menu on this page https://colorlib.com/sparkling/ to my page . I would really like to use it but I don’t how. Could anyone help me please ?
The best place to start is by following steps described in theme documentation.
If you are still having problems, please let me know with that you are struggling and I will try to help you from there.
Is it possible to make the slider image using the pages? I read the documentation is for the post.
Because the slider only for static title, not for the new post
No, it is not possible for this theme.
The easiest method is to use some WordPress plugin from WordPress.org to replace slider that comes with theme.
