Yes this is actually becoming quite popular at the moment. Same with buying and hand coding a website using a bootstrapped based template.
Interesting thanks I'm giving that a play with over the weekend. It's also quite common for a lot of people to convert WordPress into what's called a headless version. This is also popular with Drupal based websites to.
And is a great application.
There is actually quite a few, add on themes/plug-ins that will allow you to do that with design with WordPress now. Not just meant for developers but normal people.
In the WordPress world they refer to them as "Theme Framework's".
@Jaali as you also have some basic coding experience depending on how much you know you may want to look at a framework like bootstrap.
That's for the same reasons why Windows is very popular with hackers. People forget to do maintenance and basic security tasks.
If you choose a good reliable web host and keep WordPress up-to-date you will not have any problems. And don't install random themes and plug-ins.
