Currently 404 page has some dummy text. Design a page so that it looks cool 🤣 https://tinkerhub.org/learn/lolol

• You can edit https://github.com/tinkerhub-org/TinkerHub-Learning-Paths/blob/main/themes/tinkerhub/layouts/404.html for this page.
• Create 404.less in: https://github.com/tinkerhub-org/TinkerHub-Learning-Paths/tree/main/themes/tinkerhub/less/layouts and add styles there.
• Refer other files in the folder for the structure
• Include that 404.less in index.less below the line: https://github.com/tinkerhub-org/TinkerHub-Learning-Paths/blob/main/themes/tinkerhub/less/index.less#L40
• use this script to convert less to css https://github.com/tinkerhub-org/TinkerHub-Learning-Paths/blob/main/themes/tinkerhub/watch-scss.sh
