This PR fixes #340 issue.

Description:

Previously, in the about section, the contributor list would slide from right to left but restart its animation before completing the full cycle. The fix ensures the contributor list completes its slide animation cycle smoothly before resetting, improving the user experience in the about section.

There was an error in the calculations and CSS styles, which caused the animation to reset before completing the entire contributor list.
