Hi everyone! Since a couple weeks ago I started to design and develop hmtl+js+css templates, also with the reactJS version, because I want to start selling templates in Themeforest.

So I was looking for ideas to make modern templates (My first idea is to make an ecological site), because I suppose a good choice to start making free templates for advertising myself.

Any suggestions about it, or tips for a beginner developer? Thanks in advance!
