Easy Quotes

If you are using the Easy-Quotes Block as a Widget, try to find out what Header Tag your Theme uses as Widget Title. Usually this should be "h2" or "h3". In your Widget Block Settings "Title" you can then set that value. Same for the CSS-Class. Under your Easy-Quotes Block Settings "Advanced" you can enter that classname under "Title CSS class(es)".

Both: While you're at the backend of your site, and trying out different Fonts, they'll get loaded from an external google location. When you've found a font that pleases you, and your quote is viewed for the first time on the frontend, the font gets automatically downloaded to a local folder. From this time on, only the local font is in use.

Just change the "Published"-Date of your quote to this time. The quote will then be shown every year at that day. The year won't matter. (So if you publish a quote on e.g.: 2020-02-29, the quote will pop up every 4 years in a leap year.) If there is no Quote associated with a day, the most recently published one is displayed.

This should be a Cache Problem. If you're using a Cache Plugin your site gets cached and can't show dynamic content. You have to switch off your Cache Plugin or try the experimental feature "Avoid caching" in your Easy-Quote Block-Settings. (This will fetch the dynamic content through the REST-API and leaves your Cache intact.)
