Nueva: Custom CSS code works in editor, but not live site (Font Changes)

First off, this is the first website I've spent a lot of time on. I'm new to coding with CSS. I took all of the coding off of websites and answers to similar questions.

I'm currently still using the trial version with Ajax loading disabled.

Here's a link to my website and a password:homecomfortsolutionsboise.comMnbb77

What I wanted to do:Have a slideshow gallery on the top of my page with text over top of it.Center the text over the imageEdit the font type and size

On my editor, it appears successful. When I go to the live site, everything is good except the font type isn't the same.

Here's the code I used:

Any other information I could provide to help you help me?Any tweaks you think I could make to fix things?Is there a more ideal way to write code to create the effect I want?Thanks for the help!

@haydenshapiro You need share site url! If your site is in trial, see how to setup password and share url: https://beaverhero.com/squarespace-how-to/#HowtoSetupPasswordShareSiteURL

@tuanphan Sorry! Here's the link and password:

@haydenshapiro It should be

font-family: Oswald, sans-serif;
color: #000 !important;

So this sort of worked. The font changed with your code, but it's not Oswald and when I opened up squarespace today to work on the site I noticed the font had reverted back to whatever it was before I was able to make it Oswald. I'm gonna play around a bit and see if I can troubleshoot some more.

@haydenshapiro Oswald is default font in SS or Custom Font which you uploaded?

I would like to use the Oswald default font in SS. It appears that when "sans-serif" follows the font, it applies Arial. When font-family isn't specified or "sans-serif" isn't present it applies a font similar to Times New Roman.

When I applied the code yesterday and wrote "font-family: Oswald" the font appeared as Oswald (the default SS font) on the editor, but not on the live site. Without changing anything, when I opened the editor this morning the font was no longer Oswald. I checked the CSS code and everything was the same. Quite interesting.

Thanks for your help!
