After some WordPress projects, came up a decision, and it was never tune up themes without creating a child theme.
Frankly, the first thing you would be tempted to do is modify directly the theme files. Then you’d probably decide to keep track of changes to avoid problems when updating.
Reached that point emerges the problem that this solution its absolutely imposible to manage.
Next evolution comes when you edit CSS file adding your lines at the bottom of the file. Not bad, but be careful with updating theme.
The best solution looked for me as the simply css plugin goodie. No doubt this is a very clean solution and upgrade proof.
But lets be honest, if you want to do something very personalized, you need to touch the code files.
So then is when child themes demonstrates its potential, its not only easy, its super clean and works like a charm.
