It's possible to add css files, I want to add some buttons but a css file should be added to the forum/website how I can do it. For example I want to add some buttons like the download button added in the following post, Also many other features likes sliders, landing page etc.

    Shinesfox if you want to add CSS to just your own website, you can use the "Custom CSS" feature under Admin > Appearance.

    Extensions can register CSS files using the Extend\Frontend extender, see https://docs.flarum.org/extend/frontend.html#asset-registration

    If you have a large amount of CSS or want to place it under version control, you can also use the Extend\Frontend extender from the local extend.php file without the need for an extension.
