Blog Format

Is it possible to change the format of the blockquote in the blog format page of Eino?

I have made format choices based on what works best in terms of background and readability for the rest of the site, but the blog page leaves a lot to be desired. The typeface font is very large and spaced far apart making it hard to read. Also the color is very light against a light background. The ‘quoting’ effect doesn’t really convey it’s a quote at all. Can any of these format choices be changed only on the blog page?

I mean can it be done easily? I don’t know anything about CSS or formatting.
