Q:

Where do I code html?

So I recently finished the HTML and CSS course at Codecademy, and I want to practice coding with html and css. My problem though, is that I don't know where to start. I've been searching around to try and find the information I need, but I can't find anything. I kind of feel like it's so obvious noone's ever needed to ask, but I don't know, so here I am, asking.
While searching for the answer to this question, I could only find sites that teach how to use html and css, like Codecademy, and sites that let you test html code like w3schools.com, but no sites that let you practice html and CSS.
Here's my question:
Are HTML and CSS created as .html and .css files on my computer?

You can use any text editor.  Try Sublime Text - download the app for your operating system and install.
Create a new file, saving it with the file exetension .html.  Be sure you saved the file in an easy to find location - like you would with any word processing document or spreadsheet.
Open a browser (Safari, Chrome, Firefox).
Click and drag your new HTML file into the tab window.
Make some changes in your HTML file.
Refresh your browser tab.
You're now on your way to learning more about coding HTML in your local environment.
