of course!! :D i think coding (HTML/CSS or otherwise) is super fun once you really get into it, if you're looking for any good resources to get you started here's some i recommend!:

• w3schools: has good references & simple tutorials overall, i come back to this one a lot!
• sololearn: beginner-friendly interactive tutorials, good jumping-off point. if you've ever used duolingo it's kinda like that but for coding!
• bootstrap 4.6 documentation: documentation for the CSS framework toyhouse uses, basically tells you what all the words inside class="" here do.
• circlejourney's toyhouse live code editor: shows your changes live onscreen as you make them, so you don't have to save every time you want to see what you did.
