Technical Details & Customization: "Power Centers": This list targets what scholars call "power centers"—large-scale units with significant funding and direct access to institutional decision-makers (Mallon & Bunton, 2005). Non-Stop Animation: The vertical-scroll CSS keyframe ensures the list moves continuously. To make the loop perfectly seamless, ensure the very last item in the list is a duplicate of the first. Interactivity: The widget is programmed to pause when a user hovers over a specific center, allowing them to read the metrics (like the Relative Citation Impact or global ranking) before clicking away (Dhawan et al., 2018; Jefferson et al., 2018). Scrolling Speed: You can slow down the scroll by increasing the 30s in the animation property to 60s, or speed it up by decreasing it.
