The recommended method of customisation of themes on your blog is by using Child Themes.
Child theme - is a kind of “add-on” on top of your existing theme. It can be used to replace existing files in your theme, add css or introduce new features without changing main theme’s code. The benefit of Child Themes is that you can continue to update the parent theme without risk of losing your customisations.
For your convenience, you can now download a basic Child Theme for your SimplifiedBlog theme.
How to use it:
- Upload it to your blog (you should have SimplifiedBlog installed).
- Customise your Child Theme: add css to style.css file, add functions to functions.php. Add files you want to replace in the parent theme.
- Activate it. Enjoy.
