How should the result of stretching a landing page on Wordpress look like?

Question

Landing pages

Hello. There is a task - to pull a landing page on wordpress, in order to carry out seo optimization through plugins. Standard layout in html, css, js is ready. I myself have never done anything like this, so I would like to be explained the very principle of work, that is, what exactly is required of me and what the result should look like, and most importantly, in short, what should be done and how (WP is not needed by the customer to change the content , but for seo, as he explained to me). The landing itself is very simple: the main file, the style file, some js and a feedback form, and pictures.

This process is called "creating a wordpress theme", you can read in the documentation , there are many tutorials on the topic "create wordpress theme for scratch".
UPD. When you create a theme, then upload the entire project (the basic WordPress installation and the theme you made) to the hosting server, make a few changes to the config and database, there are also tutorials, you can search :)
