Too many lines of CSS. Should I use a child theme?

Hi there,

i would recommend a child theme once you hit around 400+ lines of CSS.
The advantages is that style sheet can be optimized, requested once and cached by the browser so you may notice a slight improvement after first load.

Thanks David. I looked through the tutorial on GP's site. If I switch, I'm guessing I won't lose any changes in Simple CSS right? I can just copy them over to a new CSS stylesheet (i.e. style.css)?

That's correct Simple CSS will still hold the code.
And yes they get moved into your child theme style.css

Make a backup of the site first, just to be safe.

Great, thanks so much for your help David! :)

You're welcome
