Hi and welcome back,
The best way to stay on top of these stylings is learning how to implement the changes you’d like. A few useful resources would be to watch this YouTube Video on using the ‘Inspect’ tool to identify and make changes using CSS.
Another option, if you haven’t already, is to install and tryout the Simple Custom CSS plugin Geoff mentioned in his last response.
CSS is a fairly simple language to learn and once you get the basics down, the rest comes pretty easy!
Please let me know if this helps and keep me updated on your progress. Have a great weekend!
Cheers 🙂
