I verified that the table headers are no longer dark blue with white text. They now have a light background with black text as expected. Also, I noticed that the dropdown option is not properly aligned under the 'Role' section. I know this wasn't part of the PR, but I just wanted to point it out for future reference.

Reviewed PR. The code is neat and applies semantic class names effectively. The use of box-shadow adds depth to elements, and dark mode is well-implemented. The code works as expected.

Changed as expected. Well done!

Hi @yany960,
I have reviewed the PR and I have ran the application on my system by following the steps you mentioned. I have found that the application is showing the table headings row with the intended background color. So, I would agree to merge the implementation to the main.

Checked that the table headers in User Management now have a light background with black text instead of dark blue and white.
Made sure the table header looks the same across the UI.
