Thank you for the answer. I didn’t realise that that plugin just did the editor without making any changes to the theme’s css.
So I would add the styles I need to the additional CSS section of my customisation section, then set them up in this too so that I can access them in the wysiwyg editor rather than having to hit up the text editor?
Is there a plugin that does both, or can I take the CSS generated by Just TinyMCE custom styles (where is it stored and plug it into my theme?)
Sorry for the newbie questions.
