Read more button and Add new comment - are not visible and need style.

I have reviewed this merge request. After applying the MR, the "Read more" button and "Add new comment" are visible on the frontend. However, the admin panel text and submitted user text are not visible due to the color style override. To address this issue, please check the issue Article - Tags links are not visible 🐛 Article - Tags links are not visible. Needs review . In comment #6 🐛 Article - Tags links are not visible. Needs review , I have created MR!12. Thank you

I have tried to apply the MR !6 but there is some error.
Please check the screenshot for the same.
