I’m trying to set the font size of a text element, however, it doesn’t appear to be being applied correctly.
Font sizes can be set in various places within the Blocs application. They can be set globally for the entire site via the project settings, they can be set via the sidebar (which will apply them as a freehand class) and they can also be set via a class added with the Class Manager. If you are trying to style a text element and it’s having no effect, it’s very likely that another class is overriding the one you are trying to apply.
If you are applying styling via the project settings, make sure the element doesn’t have a custom class applied directly to it that has text values as these will override the text settings applied via project settings.
