Snag in Google Docs to Blog Posting!

As one meets with a problem, he/she wants it to be solved earlier as far as possible. Whenever there is difficulty in publishing my Blogger blog posts through Google Docs, I try to find out other ways to remove it. One such instant: whenever I typed a text in Google Docs' Document page with a different font and font size (other than the default), inserted an image in it and published my post (article) in the blog, I found that there were always more than one alteration in the font sizes in the post making it look bizarre. Later I noted during such difficult blogging that whenever I highlighted the first paragraph, there was an underlining of the first few lines of it! I tried then different ways to remove it. One that clicked lastly was: selecting the whole typed text present in the document (including the image) and changing the font size first to that with lower numbers one by one, and then increasing the size to that wanted one, again one by one! When I published this document then, I did not get any alteration in size and the blog post was neat.
