I have created content using html in a new page in a Drupal 7 site, with existing styles applied from the same style sheet that is used to style other similar pages. The css selectors are the same but no style is being applied when the new page is saved. If I copy the similar html from an existing page created in the same way and paste its content into the new page as a test, it is also not formatted in the new page using the style.css file.
The new pages are visible in the menu and can be displayed, but not with styling. Can you advise?
