Make entry Images float left and title/text align right EXCEPT the first entry

Hi, I’m Nora.
Thank you for your previous help on creating widgets.

I recently want to make some adjustment on the display of the articles. I want to make the entry images float left and the title/preview text/continue reading align-right but EXCEPT the first article.

I only know how to adjust the image to align-left by adding custom CSS, but I couldn’t find a way to move the titles and make an exception for the first entry.

I’ve noticed that the entries seem to be included in one column, so that’s my difficulty. Is it possible to make it happen?

Thank you.
