@PRAteek-singHWY if I am not wrong the original theme of the background was not white it is introduced in PR #768 and now in this PR we are again struggling with readability issue because of theme changes. Is this theme change planned for the website?
If not I propose to get theme from system preference and our website should be dynamic for both dark and light.

Hi @manshusainishab
No new background color was introduced in PR #768. That PR mainly restored the body background to white, which had been changed earlier in PR #767.
In PR #767, the background was modified from white to #010817

That PR was raised to resolve the issue where a white background appeared during overscrolling. PR #768 addressed the overscrolling behavior itself and restored the default body background to white. You can also check the video attached in PR #768 to see what was breaking earlier after PR #767.

To be sure, you can also check some older merged PRs where screenshots are attached — the background there is clearly white.
Regarding the readability issue on the explorer, it is already being handled in PR #788.

Also, your thought about supporting theming based on system preference sounds like a good idea. As far as I know, a specific theme design has not been formally discussed yet, so it might be worth bringing it up with the maintainers to see how they would like to approach it.

Thanks for the clarification @PRAteek-singHWY I thought the original colour was not white because when I was fixing the readability issue I applied the text with white colour because background was dark at that time on main branch
