Hi there!
Thanks for your query.
Did you mean this one? https://prnt.sc/D45YDWTplzyQ
Here is the code responsible for the image:
#sp-footer .container-inner:before {
content: url(../images/footer-shape-1.svg);
}
Please use this code in your custom CSS to replace the image with your own. You need to upload your desired image through the media first and then copy the image URL and paste in the above code.
If you want to remove then use the following code snippet instead:
#sp-footer .container-inner:before {
content: none;
}
Note: Path towards custom CSS(Joomla 3): Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
Hope this helps!
Best Regards
