I don’t understand what you are saying, if you have it inline it’s not scss, scss needs to be preprocessed to be used in production, codepen does that automatically for you
On the page where I have the HTML for the calculator, I have …
I tested .scss file. However, I Don’t appear to know how to connect that to the HTML file. 
do you mean not in codepen? because codepen deals with scss automatically once you set the settings appropriately
you should research how to include SCSS in your project, then, because it needs to be converted to CSS and you need some tool that does that
Otay, I did a bit of research. Possibly I can watch one or more SCSS videos. I Haven’t been checking this thread often, as you likely can tell.
at this point as the topic has completely moved away from the original question , maybe open a new topic when you need help
I Coverted the SCSS to CSS. So this whole case is Solved!
