We have three major types of Fonts, Italics, Bold and Normal. Each one has it’s own meaning and can be used in different contexts. But if you are deciding on a font for your website, one must never choose or opt for Italics.
There are many reasons why we should not use it. One of the reasons is that it doesn’t appear professional, especially if you are developing a website for a company.
A key thing to note is that themes which you download from the Internet or any application which generates some feed, more often than not it appears in Italics. And sometimes you might not even notice it especially of your focus is on somehow getting the feed of your app in the website.
Most of the public facing websites do not use Italics. So it always makes sense to follow that practice.
