how to create a website?

There are many way to go about creating a website. Which way you take can depends on a few things such as:

1. The purpose of the website: A simple website like a personal blog may not require a lot of skills or effort to create. Something like a restaurant website with online ordering and reservations requires some skills but there are products available that make it easier. A complex website like youtube for example will require a lot of skill and time.
2. The complexity of the website: If you are creating a site for just displaying text its fairly simple to design but a site that does photo editing in your browser will need a lot more thought put into it.
3. Is the site static or dynamic: A static site does not store any data from the users using the website. A dynamic website will store information like comments, user logins, sharing, etc. A dynamic website usually need what we call in the industry as a back-end and most of the time needs to custom coded.

Based on the purpose and complexity, if you like to do this yourself and do not want to learn coding then you can use a site like wix..com. If you like to code then you'll at a minimum need to learn HTML, CSS. If the site is complex you need to learn Javascript or Java or Python or PHP
