Internal Notes for Reviewers

I noticed during the demo video that was filmed the BG img for the training hero banner repeats instead of being seamless. Fixed now.

PR Summary

This pull request introduces an enhancement to the CSS styling of the training site. Specifically, it adds the background-size: cover; property to the CSS rules for elements with a hover state. This change ensures that background images are scaled to cover the entire element, maintaining their aspect ratio and filling the element's space without distortion. This enhancement improves the visual presentation of elements with background images when hovered over.

Test Suggestions

• Verify that elements with background images scale correctly to cover the entire element on hover.
• Check that the aspect ratio of background images is maintained when the background-size: cover; property is applied.
• Ensure that the change does not affect other styling properties or cause layout issues on different screen sizes.
• Test the hover effect across different browsers to ensure consistent behavior.
