Everybody loves high-quality and free icons with a massive number of items and Gemicon is an exciting set that will surely get your love.
This set consists of 600+ icons that are available in both PNG and PSD.
It is offered in multiple sizes (16*16px, 32*32px, 64*64px) and PSD version is created as a shape layer so that it can scale.
Gemicon is completely free to be used in both personal + commercial projects.
We have icons as images, fonts and here is an inspiring gallery of icons with only HTML-CSS.
One Div is an inspiring set and showcase of icons that are created with a single
<div> element and with the help of creative CSS3 rules.
There are 55+ icons, new ones are added from time-to-time and it is possible to click the source codes with a click or download them.
The icon set may not be the perfect fit for everyday use but it is a very nice source of inspiration.
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.
P.S. The rules in the CSS generated are named similar to Twitter Bootstrap which is nice for the fans of the framework.
