@nirotem Okay, so that tells us that, the embed code, in the absence of any other javascript/jquery references should function just fine. This indicates that there is definitely something in the Weebly environment that is interfering with the proper functioning of the BibBase embed.
Weebly loads version 1.8.3 of jquery and BibBase loads version 2.2.4. While you can run multiple versions of jquery on a single page, there exists the possibility of conflict. There is a "noConflict" solution to this but you'd have to make some modifications to the jquery code and that's probably not something you can or want to do. And, it's not a certainty that this is the source of the problem.
In the Chrome code inspector, I stripped out all the page elements (header bar, logo, navigation, etc.) other than BibBase and the scroll problem persists which possibly indicates an issue with the Weebly javascript that fixes the header bar (where your logo and navigation menu reside) to the top of the page after you scroll down the page (you'll see some of this special behavior on other pages in your site where, upon scroll, the header bar changes color from burgundy to white and the navigation menu items change font color from white to black). There's a way to disable Weebly's scripts at least so you can test BibBase in the absence of those scripts but you'll need to modify the page html for that. And disabling those scripts will make that particular page not work the same way as the other pages (mobile behavior, scroll behavior, etc.). So you may solve one problem only to have to figure out another.
Hmmm. Thorny problem. I'm sorry that I don't have a definitive solution for you. My guess is that you're going to have difficulty getting BibBase to work properly on Weebly. Getting Weebly devs to look at this particular issue is likely a dead end as all current development work at Weebly appears to be directed at the Square site builder (since the acquisition of Weebly by Square) and virtually nothing of update significance has been done with the Weebly Site Editor in years (which frankly is a red flag for the longevity of the platform). You might contemplate hosting your site directly with BibBase. To use your own custom domain, as you've done with Weebly, would require you to sign up with their Professional Plan at $20 per month which is a bit steep for a site primarily centered around academic works. I have no idea what their site editor looks like or how flexible it is with respect to building regular site pages, i.e., pages not related to publications or academic works. My guess is that it's not a particularly great tool (I was not able to even find a screenshot of their page editor).
Your other options include checking out other web hosting platforms that may be able to run the BibBase embed without any problems. You can use the usual free trials of most Weebly-similar platforms (Squarespace, Wix, MailChimp, etc.) to test them out without necessarily committing to a particular platform.
