You can tell many designers by checking their typography. Because this type is the basis of design.
You can use types to create the entire design. You can also use the type design as a basis to get a subtle queue from the selected font. In order to improve the typography in the design, we must first learn the basics.

Develop a vocabulary of description types. Understand terms such as tracking, kerning, and leading meaning. The article A Beautifully Illustrated Glossary Of Typographic Terms You Should Know is a good visual resource for learning these terms.

Then, if you want to fully understand how to apply typography to the web, please see Web Typography: The Elements of Typographic Style Applied to the Web.
Finally, learn how to pair fonts. FontWolf and FontPair are great resources. Pairing fonts can greatly change the dynamics of the design.
