Just thought I'd give a little bit more detail here - you can put an id on anything, but they should really only be used for an item that only appears once per page, that will have its own styling or that might need to be easily targeted on its own in JavaScript. Classes are more flexible - they can be put on multiple elements to style or easily select them together.
I'm not going to say you should never use IDs, though - they have some benefits. One is using links to various points on the page - say you had a long document on your web page that had headings. You could provide table-of-contents-style navigation on the page that would link to that location on the page, so the user doesn't have to scroll and look for it - that is done with IDs. I also mentioned JavaScript - an ID can be useful if there is functionality that you only want to attach to a single element on a given page, because selecting by ID in JS is pretty simple and wouldn't be affected if you refactored your HTML or added more items to a class (as long as you don't remove the ID).
It's also important to note that an element can have both an ID and a class, so you can use them both as needed.

using ID or Class it doesnt metter use whot you preffer :), sometimes are good Classes but sometimes are IDs
Classes for multiple changes in your code and repeateble
ID for single change/ hot fix / JavaScript / .....

19,141 PointsFor a site with HTML/CSS/JavaScript, you just need a text editor. Your OS might come with a basic one (like Windows NotePad), but most people like to use one that actually has code highlighting and such. A couple popular ones are Atom and Sublime Text. There are others too - feel free to do a quick Google and choose the one you like the look of. When you're building your site, just make sure you have the correct file extensions (.html, .css, .js), and you're good to go.
To implement additional things, like libraries (JQuery for example), just hop over to its website. There are usually instructions online for installing whatever you decide to practice with in the future.
