Your story is a classic story of why you want to have an external stylesheet instead of an internal stylesheet. If you have an external stylesheet and a reference to that stylesheet in each (x)html file, changes can be done in the stylesheet and effective in all files that reference to it.
So, your answer is to create an external stylesheet. Move the styles in it you apparently defined in your original HTML file and create a reference. Even creating the links can be done easily. Select in the Book Browser all the HTML files, right-click and appoint the stylesheet to the files.
After that a change in the stylesheet is effective in all files.
