It’s very convenient for front-end developer if you use font awesome icons in your design. To use font awesome in photoshop:
- download the zip from https://fontawesome.io/icons
- install FontAwesome.otf
- go to cheatsheet http://fortawesome.github.io/Font-Awesome/cheatsheet, copy the icon directly
- paste in photoshop text layer, you should see a square
- choose FontAwesome as the font-face
Again, front-end developers will love you when they get to write the CSS.
