How to choose the correct design of the article, which will correspond to the general view of the site?

The other day we made an article for our site. But I do not really like what the font looks like.

Please tell me which font will look good in the articles on this site. If you have any comments on the design of this site, I'd be happy to hear them.

My English is not so good. So do not hesitate to ask when something is wrong
