You can get the embed code in two ways:
- get it on the banners list page. Use a "get HTML5 code" point in the banner settings
- when you edit the banner, you can get the code in the "Publish" menu, click on the "Copy HTML5 code" menu point
Then you'll see a settings form. Where you can set a banner type (animated or an image), should a banner be responsive (adapt to the container), what window it should open in (in current/self or in parent/blank).
When you set all the settings you need, copy the code.
Now the embed code is ready to be implemented in the site. Open a site page code, find the place and past the embed code there. Save changes. Clear site cache if you need.
Occasionally, banners don't load on some sites without a protocol. In those cases, you can add https: or http: (depends on your site protocol) to the banner URL.
If you want, you can check the banner code. How to do that you can read in the article Check a banner code.
