The following is a guest post by by Parker Bennett. While icon fonts are efficient and easy to use and scaleable and all that, one of the classic "strikes" against them is that the icon can only be one color. Parker has a brand new project that solves that issue in a simple and clever way. I'll let him introduce it for you.

Even though the future of icons will likely be SVG, here in the present, icon fonts still offer a compelling alternative — with super easy styling of color, size, text-shadows, hover effects and more using just CSS. Icon fonts are still awesome.

One big advantage SVG has over icon fonts is full color. But icon fonts don’t have to be limited to just a single color. By overlapping two or more elements we can create unique “multi-color” icons with a contemporary flat look. If you’ve ever done any two-color or screen printing, it’s a similar idea.

I call them Stackicons.

For each color, we use a separate pseudo element, then use absolute positioning to stack them on top of each other. (If you want more than two colors, it will cost you a non-semantic span.)

/* @font-face to load icon font... */
    
    /* horizontal button row: inline-block vs float makes positioning easier using text-align */
    
    /* any class that starts with "st-icon-" */
    [class^="st-icon-"] {
      display: inline-block;
      vertical-align: top;
      white-space: nowrap;
      /* child elements absolute */
      position: relative;
      /* remove inline-block white-space */
      margin-right: -.16em; /* 5px */
      /* if not already universally applied */
      -moz-box-sizing: border-box;
      -webkit-box-sizing: border-box;
      box-sizing: border-box;
      /* padding here for text, icons replicate this using size and position:absolute - padding makes touch-target bigger */
      padding: 0.143em;
      /* units used in font: 1em = 2048, icons 2400 wide, so icons are 1.171875em (2400/2048). Add padding x2 to get size: */
      height: 1.45788em;
      width: 1.45788em;
      font-size: 1.815em;
      /* text hidden old-school */
      text-align: left;
      text-indent: -9999px; }
    
    /* position:absolute stacks pseudo elements - extra <span> in markup = 2 extra pseudo elements */
    [class^="st-icon-"]:before,
    [class^="st-icon-"]:after,
    [class^="st-icon-"] span:before,
    [class^="st-icon-"] span:after {
      display: block;
      position: absolute;
      white-space: normal;
      /* match padding above */
      top: 0.143em;
      left: 0.143em;
      /* undo text hidden */
      text-indent: 0;
      /* inherits size from parent, ems cascade */
      font-size: 1em;
      font-family: "Stackicons-Social";
      font-weight: 400 !important;
      font-style: normal !important;
      -webkit-font-smoothing: antialiased;
      -moz-osx-font-smoothing: grayscale;
      font-smoothing: antialiased;
      /* screenreaders */
      speak: none;
      /* transitions here */ }
    
    .st-icon-amazon:before {
      /* character code - unicode private use area */
      content: "\e079"; /* black "a" */
      color: black; }
    
    .st-icon-amazon:hover:before {
      color: #626262; }
    
    .st-icon-amazon:after {
      content: "\e080"; /* orange smile */
      color: #ff9900; }
    
    .st-icon-amazon:hover:after {
      color: #ffbd59; }

Using rgba values, we can even do some color mixing to give us more colors. If we really want to push the limits, we can use -webkit-background-clip: text to give icons a -webkit-linear-gradient background.

Yes, it’s a bit on the hacky side: It takes some design forethought, and the ability to generate an icon font. There are more moving parts to manage. But it also offers a lot of flexibility, especially using Sass variables.

Stackicons-Social

To show how it works, I made a free, open source icon font, Stackicons-Social, and created a Sass “Construction Kit” to generate the CSS for both single color icons and “multi-color” versions of over 60 social brands.

I also created a range of button shapes in the font, from square to circle (plus icon-only), and have classes that override the shape on the fly. Want circular icons? Just add the .st-shape-circle class. iOS style? .st-shape-rounded3.

Putting It Together with Sass

Behind the scenes, there is a group of .scss _partial files that Sass compiles. If you’re comfortable using Sass you can customize things extensively just by changing variables in this "construction kit":

• fonts-stackicons-social - Path to stackicons-social font.
• colors-social–2014 - Color variables for social brands.
• unicodes-stackicons-social - Font unicode characters abstracted into variables.
• construction-kit-stackicons-social - This is where we generate default values for icon size, margin, padding, shape, color, hover-style, etc. (Play here.)
• css-defaults-stackicons-social - This does the CSS grunt work to create each .st-icon-($brand) class.*
• override-shapes-stackicons-social - Let’s you override the button shape on single-color icons using classes: st-shape-square to st-shape-circle, plus st-shape-icon.*
• override-colors-stackicons-social - Some examples of “color-styles” for single-color icons to demo different options. Lots of extra CSS, so it’s commented out by default.*
• multi-color-kit-stackicons-social.scss - Like “construction-kit” above, but for the .st-multi-color class: generates default shape, color-style, etc.
• multi-color-css-stackicons-social.scss - Like “css-defaults” above, this does the CSS grunt work to generate each multi-color .st-icon-($brand) class.*
• multi-color-override-shapes-stackicons-social - This allows you to change icon shapes using classes on multi-color icons.*

* Because Sass doesn’t allow us to use variables within variables, this uses a lot of @if statements to generate the .st-icon-($brand) classes. Ugly, but marginally maintainable. There are several @each statements, listing the brands to output. Ideally, you would go through and edit these lists to limit the CSS output to only the brands you need.

Rolling Your Own

There are some great free resources for creating icon fonts, including icomoon.io and fontello.com. I use Adobe Illustrator and Glyphs on the Mac. (Glyphs Mini is a lower cost option that limits the units per em to 1000. They also offer student pricing.) To generate the web font versions, I recommend FontPrep, which Brian Gonzalez just made open source. FontSquirrel is another good free option. (If you’re interested in more workflow details, let me know in the comments.)

You should also check out some random dude (P.J. Onori) and his iconic project. He also has some helpful tips on using icon fonts.

We are proud of our alums and their constant achievements. Three of UMBC’s alums, in particular, have made it in the news and we thought you should know! Read about Sean Scheidt, Zofie Lang, Terry Nolan and their stories of success.

Sean Scheidt ‘05, visual arts photography, is featured on BuzzFeed for his before-and-after photographs of burlesque performers. Take a look at his ability to create and capture these artful transformations, or as BuzzFeed’s Matthew Tucker puts it, his ability to challenge “preconceptions of the performance art.”

More of Scheidt’s intriguing photography can be found on his site, seanscheidt.com.

Zofie Lang ‘02, psychology and sociology, will be presenting her 12-piece assemblage at BlackRock Center for the Arts’ show, Collective: a visual narrative of tale, time, and thought. She is proud to be presenting alongside artists Renee Lachman and Henrik Sundqvist. Lang will use digital photography, found objects and photo montage to explore folklore, literary tales and their meanings. Details about the show can be found on BlackRock Center for the Arts’ site.

Lang’s personal site, zofielangfairytales.com, also provides a sneak peek of some of the pieces she will be presenting at the exhibit.

President of the Arbutus Business and Professional Association, attorney Terry Nolan ‘82, political science, is committed to his job and prides himself on giving back to and growing his local community – it’s where his heart is, explains his wife, Patti Sue Nolan. Nolan works out of his law office in Arbutus and has made a name for himself amongst the town in which he lives. Read more about Nolan’s success in The Baltimore Sun’s article.
