The blogger changes the line spacing and fonts in published posts when everything looks fine in the draft. How to deal with it?

Question

css

The blogger unhappily changes fonts and paragraphs in published posts from one paragraph to the next.
A typical example:
Everything looks great in the post editor, all the text is in one font and the paragraph between the lines is small. Publishing (or Preview mode) - the distance between the lines has become 2 times larger in several paragraphs (sometimes this happens for the entire text, sometimes for only a few paragraphs, sometimes the distance remains the same as initially in the editor, but rarely). Often, phrases written in Latin become a different smaller font than the general text.
Please tell me how to deal with this!

Answer 1

To paste from Word, it is better to use the combination Ctrl + Shift + V - to paste text without styles. Then it can be formatted in the Blogger editor.
