Hey @Nikita - yes absolutely start building simple websites, we all start out as a beginner. WordPress is both easy and difficult. Its easy because it is designed to be friendly to use, and to get going on WordPress the amount of work you need to do is minimal. A big however though is that to be good at WordPress you really need to know a lot of things outside what you have been introduced to here at FCC. You need to know the WordPress way of doing things, the way and order it loads all those files, and how to override some of this behaviour. You need to know PHP, no getting around that. Fortunately PHP is really easy to get into as a second or third language. Learn about child themes ( different concept from a theme ). And plugins, knowing what to use and how to choose a good one simply comes with experience and exposure.
There are lots of free courses on WordPress, and some inexpensive pay ones on places like Udemy. If you find that WordPress is for you, there are a few more expensive places to dive deeper and really learn the inner workings.
I’ve come to enjoy WordPress, and to learn a fair amount about it’s inner workings, but the amount of work I put into this has been every bit as involved as getting the Frontend Developers certification here on FCC, so be warned!
