Author Notes

1. While implementing the changes, I noticed that some styles for ColorInputField component were added in all the components where ColorInputField was imported and used. The styling of this field was also causing issues when moving to the sidebar.
2. This PR also contains changes to fix ColorInputField such that it doesn't require additional styling in importing component.
3. I found the old ButtonStyles component design didn't look good in sidebar. Thus, I added a new ButtonStyles component in newConsole with comparatively better design.
4. This PR is dependent on #719 for live preview in static pages.
