Can you earn revenue from products built with HTML and CSS?

Of course you can if you keep an open mind to spot the opportunities. I've earned a decent living for a couple of years by making HTML templates and publishing them on top marketplaces with no boss, no commute, no alarm clock. Currently I sell them on my own website https://htmlrev.com with exposure from my Twitter audience https://twitter.com/luciantartea The website itself is noting more than a HTML page powered by Gumroad for payment and item delivery. I've created an ebook to share with you my 5 years template making experience with results and tips. Would love to have your support on the Product Hunt launch page where you will find 2 complete free chapters https://www.producthunt.com/posts/how-to-create-and-sell-html-templates
