Hi @landondavis
If you haven’t make edits in themes files yet, then the first things I can suggest is:
– have a backup of your theme’s files which you can restore in case anything goes wrong
– work from FTP. This way if anything goes wrong, you’ll be able to revert the changes. If you’re not sure about your FTP credentials, please contact your host. They should be able to help.
To make your changes future proof, consider creating a child theme: https://developer.www.ads-software.com/themes/advanced-topics/child-themes/
which you can edit without having to worry that your changes will be lost by an update.
Many theme developers create official child themes, so asking your theme’s developers whether they have a child theme could be a good start.
The way you can work with child themes is that you copy over the files you want to change, and make the edits only in the child theme. E.g. if you need to edit the header.php of the parent theme, then first you need to copy that over to the child theme. Then you can make the edits at the child theme.
I checked the linked page, and I didn’t see the slider overflowing the sidebar/widget area there. Were you able to figure it out?
I also checked a few posts, but I didn’t see any slider there either.
