Hello.
I would like to make a website like http://www.jww717.net/ .
I learned basic HTML and CSS.
I am stucked.
Questions :
What programs do I need to learn to make such a website?
How do I link my pages together?
How do I make so many index ? (The first few pictures than the main index)
How do I make it like I can update blog posts on the website immediately?
In Codecademy there is option in the learn page on makeing a website and making an interactive websites so try out those courses.
I tried.
It does not teach me how to link my pages together nor how to make it into a blog-like website
Actually to make a public website you need to buy it as a domain and to link pages together, well that is another adventure for you to find out through many ways… 
Good luck though!
Try learning HTML, CSS and JavaScript.
the structure for them is.
<!DOCTYPE html>
<html>
<head>
<title>
<!-- write your website's title here (it won't display) -->
</title>
<style>
<!-- write your styling (CSS) here -->
</style>
</head>
<body>
<!-- write your HTML here -->
</body>
<script>
//write your JavaScript here.
</script>
</html>
I recommend you learn the basics here. If it’s not enough, try looking for the “world’s largest webdeveloper site”. 
Also, to have a place where to write your code, you only need a note pad. Write your code on a notepad, save it as an .html by writing .html at the end of the name. Also, save it as “all files” and codification UTF-8. That’s for advanced things but it’s better to get used to having it now.
What is your recommendation of learning ‘‘world’s largest webdeveloper site’’?
I have learned the basic html and css.
Do you mine contacting me personally?
