Vector icons for the website.
This is my first time not using pixel images to decorate a website. Instead, all icons are saved in the SVG format and converted to a webfont, which is then used to style regular HTML characters into icons.

For example, here's a font with the above icon set - VectorIcons.ttf

The advent of webapps like IcoMoon and Fontello not only made the process of building @font-face kits an absolute no-brainer, it also gave an easy access to hundreds of existing vector icons, many of which are free and of production quality.

When coupled with now virtually universal support for CSS text-shadow, box-shadow and gradients, this almost completely eliminates the need for raster form of smaller decorative and nuancing elements.

This is a very big deal and a great time-saver.
