yaooqinn opened a new pull request, #54573: URL: https://github.com/apache/spark/pull/54573
### What changes were proposed in this pull request? Replace the custom `.btn-spark` CSS class with Bootstrap 5's built-in `btn-outline-secondary` class. ### Why are the changes needed? The custom `.btn-spark` class (lines 45-59 in webui.css) defines a legacy gradient background, box-shadow, and hover transition that duplicate what Bootstrap 5 provides natively. Replacing it with `btn-outline-secondary` simplifies the CSS and ensures consistent look with the rest of the BS5-upgraded UI. Part of SPARK-55760 (Spark Web UI Modernization). ### Does this PR introduce _any_ user-facing change? Yes — the "Go" buttons in paged tables and stage page now use Bootstrap 5's outline-secondary style instead of the custom gradient style. The visual difference is minimal. ### How was this patch tested? - Verified no remaining references to `btn-spark` in the codebase - Visual inspection of paged table "Go" buttons ### Was this patch authored or co-authored using generative AI tooling? Yes, GitHub Copilot was used. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
