Hi,
To edit the location of the Slider:
1. Please log in to your account.
2. On the right drop-down menu find the Layout tab and click on it.
3. There you can see the Edit Layout, Edit CSS, and Edit JS tabs. There you can edit/fix your page layout, code, and CSS styles.
The fastest and easiest way to edit Slider is to delete class="index" from <header class="index" role=" banner">. It will move your slider directly below the header area but will change the style of the header.
