I am currently making a website on HTML js css... I want to know what is the best WebHosting service that is cheap
If you are just starting out, I recommend Firebase Hosting (https://firebase.google.com/pricing).
This would suit you because it is free to get started. As long as it is only you and a few friends trying it out, you will find the cost is $0.
Only when thousands of people are using it, or you are storing hundreds of images or videos, will it start to cost something, and that cost is predictable.
