There's a little white downward pointing carrot next to "National Menu" in the top left corner of this website. When I inspect the :after element with chrome and firefox the content is just an empty white box. Copying that content seems to be no use, and I can't grab it from the main.css stylesheet either. I'd like to know how to reproduce that carrot, and further I'd love to know how to handle situations like this in the future.
It's char 59401, but the magic lies in the font
That specific icon is http://fontello.com/#search=angle,down
On how to handle this in the future, there are a lot of fonts that are icons. They make it simple to use vector based icons and can be colored like any other font. When you see something similar to
<i class="NameOfLibrary NameOfLibary-IconName"></i>
It's typically an icon font where you can look up the classes
If the icons has been integrated into the main stylesheet and there are no classes to be found, inspect the ::after and find out what font it's using, then look that up
