In Microsoft Visual Studio Professional 2017, when I edit a JavaScript or CSS file, the Intellisense Quick Info for Members, Objects and other keywords don't appear. However, when I open the same files in Visual Studio Code 1.66.0, Intellisense Quick Info is shown properly. This results in me failing to interpret the significance of JS and CSS functions and keywords, hence, causing a ream of inconvenience to me. Why is this happening and how can I make Quick Info appear properly for JS and CSS files in Visual Studio 2017? Any help on this matter is greatly complimented.

Regards
