Why does my post show up in the preview in different colors?

If you edit a post and you look at the preview, sometimes you notice deviations like different text colors, font sizes or fonttype.

Most likely it's because you copied text from an HTML source (like a webpage) and so the text carries al the HTML formating in the background.

If you copy text from e.g Word of a webpage, make sure you do that with the shortcut CTRL+SHIFT+C (Mac: COMAAND+SHIFT+C) and paste the text with CTRL+SHIFT+V (Mac: COMMAND+SHIFT+V).

By using these shortcuts, you make sure all formatting will be removed from the text.
That way, all the strange colors, font sizes and font types will be gone.

There is another way to get rid of the unwanted formatting:
Paste the copied texst first in a simple editor like Notepad. From there copy the text and paste it into the post.
