@meetarora10 but this design is already there in all the pages as all the pages are linked with the styles.css i thouht you were changing the scrollbar why did you removed the code from the css and added it individually in all the other pages wouldn't it make the code bigger in other pages and keeping it in styles ensured that the scrollbar is there in any new page added to the website later right

@aditya-bhaumik yes it was present but scrollbar was not visible in the website. So I added in individual files , trying to make it visible in all the pages in the website.

If you say I will change the styling of the scrollbar @aditya-bhaumik

@meetarora10 it is visible as i checked it in all pages you can try changing the scrollbar to some better design but dont remove it from the styles.css and also remove the extra code you put in html files

i am closing this pr you can create another pr with the changes

Make a scrollbar which will look good with the projects color theme
