Among the WordPress themes from Greta Theme, TheFour Lite is one of the best themes to use for business. Besides a business theme, you can even customize it easily to make it a personal blog. It comes up with a decent and clean appearance that gives you relaxation and friendliness when using.
The most notable feature of TheFour Lite is its speed. This is a super light and fast theme so that you can have the smoothest experience. It’s also SEO friendly and responsive in all devices.
I think that if you are a beginner and want to find an easy and simple business to use, I highly recommend TheFour Lite. It's compatible with Gutenberg and all the browsers, already optimized for SEO and responsive in all devices. The speed is excellent and the design is clean and decent. I suppose that these features are all you need to run a simple website for yourself.
If you upgrade to the Pro version, a lot of extraordinary features will surprise you. Therefore I think you should try this free version first and then buy the pro one.
