How would I apply code(JS, HTML, and CSS) to a website?

Question

Do I put it in a text space on the website or what??

Answer 1

HTML is a language used to process text, just as in the same way you have your text editor.
Now CSS is a language that is used to keep the styling of the word document away from what the document actually says.
HTML —> content.
CSS —> style of content.
JavaScript is used to make both of these dynamic. That is, it controls both of them, drop-down menus. Creation of new tags, i cannot see color blue so i click accessibility/helpchangeColourOptions, i just liked someone. All these and much more. It makes it come alive in essence. But all of these THREE, sometimes more, MUST be somewhere in a computer. A special type of computer people can connect to and get these documents (a site) so you see where database comes in. Now the database too needs a language to act as a transport van between the user accessing the documents and the database processing this. Hence PHP.
PreHyperText Processor.

It depends on what kind of website design you have in mind. What were you thinking about? I'm might be able to help you out. Also I recommend you use Notepad++ as your ide for creating a website. If you can't get that, then use plain old notepad
