@tkister Okay, I was just trying to figure out if your “wish” was specific to Webflow or looking for general knowledge about classes.
What users are referring to in creating an extra page (that they either keep and don’t make visible or delete when the project is finished) is this – you build the elements you plan to use, give them a class or use the main class (for example ALLH1headings), then you style them via the CSS designer controls. Then those classes with the styles applied are available to use throughout the site. Taking that one step more, say you want a feature section to use on a few different pages then you would build your feature section and you could either copy and paste it to other pages. If you copy and pasted the features section for use on multiple pages but then wanted one page’s features section to look different you could add a nested class just for that page. Mat Vogels (https://webflow.com/mat) created a clonable Style Tile (Webflow - Style Tiles) that works as a bit of an example on how you could setup your styles to be used throughout the other pages of your site.
There isn’t too much to explain about how the classes appear in the actual code other than a “w” is put before the Webflow default classes, and spaces and underscores are replaced by dashes. You can use the web inspector on your browser to inspect the code and see how the classes display. In the example below the class=“w-section” was the default class for a section – “base-full” was the class I added to style the section.
Honestly, I think class naming strategy and class nesting strategy comes down to the preferences of the person doing the work and is more than just related to Webflow but the design/development community at large. However, it’s been pretty widely discussed in the forums and here are few links…the post were Sergie gives some tips is older but still mostly applicable.

The videos do cover naming so you might give them another look.
Anyway, hope that helps.
