Theme child on wordpress

Question

I'm new on wordpress and I have readed about childs themes.

My question is, Is that neccessary that I create my self child theme or can I use other theme child created ? that's to say, if I use a child theme created for other person, that theme will not change that I do it?

Answer 1

The way a child theme works is that it overrides the default settings of your chosen theme. So you only have to allow for the parts of the theme that you want to make your own.

As long as a child theme created for someone else is based on YOUR main theme, then you could use someone else's child theme.

For example, if someone has a child theme that works for Wordpress 2017, you can upload and modify that for your own use, for example to change the css or create your own header and footer files (usually named header.php and footer.php). These are the things I do most often.

If you don't already have a child theme for your chosen theme, though, it is best that you create one yourself. It is quite straightforward, all you have to do as a minimum is create a child theme folder with a style.css in the correct format and a functions.php file in the same folder using these instructions https://codex.wordpress.org/Child_Themes

If all you want to do is play with color and fonts, you might find it easiest to just use the Wordpress Theme Customizer. These changes will be maintained during upgrades in a custom.css file (or equivalent) so you shouldn't need a child theme.

Hope this helps
