There are very nice icon fonts out there, both free or paid, and they provide flexibility in several ways compared to using standard icons.
However, a major drawback is that icon fonts usually come as a single font file where we need to load the whole file to use few items.
You’ll remember Fontello that allows us to create custom icon fonts via a web interface. Font Custom, an open source tool, is a command line alternative for it.
Simply target the folder that has your SVG or EPS icons and it’ll generate the fonts. Also, it’ll keep watching the folder in case you make any changes to the icons and will always keep the fonts up-to-date.
Notes: The rules in the CSS generated are named similar to Twitter Bootstrap which is nice for the fans of the framework.
