Sans serif fonts are often used to convey a contemporary, minimalist feeling to a website. Serif fonts are considered more traditional and may convey “confidence” in your message.
Mixing font styles adds texture to your site keeps your pages interesting. Pages with texture are more likely to engage viewers – but choose your type carefully or you’ll wind up with a hodge-podge that nobody wants to look at. You have invested a lot of time writing clear and concise content, and if you really want viewers to read it – don’t make their life more difficult with poorly-chosen type faces. Don’t forget that choosing the right color and size is just as important. But I’ll leave that subject for another article.
TIP: Always test your site in all the major browsers since type and page design looks different depending upon the browser.
