Adding custom CSS1 user found helpful
1) Can someone confirm if this applies sitewide to the theme, or just this page in question?
2) Could a better location for theme customization be considering for future versions of 5.7? i.e. not requiring going into a page's attributes to make these changes?
If you add style customizations in the CSS section of the customizer, and then save them, you can choose whether they apply to the whole site or to just the page in question.
Re: 5.7 CSS. What's weird is the first time I tried to do this I could have sworn it did not ask me to apply it sitewide or just the page in question. Now I see the prompt. Not sure how I missed it before... anyway, thanks for the reply.
