How Can I Reduce FOUT?

I've created a site using fronts from TypeKit.

What can I do to help eliminate the flash of unstyled text before the site loads? It looks really bad!

Hi Natasha, I was running into similar issues with Typekit. If you go the async route, there are some options.

    // Load typekit font
    // add .wf-loading class to styles to account for FOUC
    (function(d) {
      var config = {
        kitId: 'YOUR_KIT_ID',
        scriptTimeout: 3000,
        async: true
      h=d.documentElement,t=setTimeout(function(){h.className=h.className.replace(/\bwf-loading\b/g,"")+" wf-inactive";},config.scriptTimeout),tk=d.createElement("script"),f=false,s=d.getElementsByTagName("script")[0],a;h.className+=" wf-loading";tk.src='//use.typekit.net/'+config.kitId+'.js';tk.async=true;tk.onload=tk.onreadystatechange=function(){a=this.readyState;if(f||a&&a!="complete"&&a!="loaded")return;f=true;clearTimeout(t);try{Typekit.load(config)}catch(e){}};s.parentNode.insertBefore(tk,s)

This script adds a couple of classes to your html element. .wf-loading is added to your html element while the fonts are loading, and .wf-active is added when they are done loading. I'm using those to sort of hack the UI a little. I created an animation that sets the font's opacity to 0% while they're loading, and the transition to 100% when the fonts have loaded. Here's what it looks like: http://www.somecallmejosh.com

I'm not 100% sold on the above idea. I get Adobe's reason for suggesting that FOUC/FOUT is cool (episode 172 of www.shoptalkshow.com). But, that doesn't make me and other users like it any more The other method offered by Typekit eliminates the FOUC, but it becomes a blocking script:

<script src="//use.typekit.net/YOUR_KIT_ID.js"></script>
<script>try{Typekit.load({ async: true });}catch(e){}</script>

Try moving all your javascript to the bottom of the page. This should make it so the CSS load first which will help. You could also try hosting the font locally (if you aren't already). Then lastly try to have as few files as possible (one CSS, one JS(maybe two if you used a framework)) and make sure they're minified.

I heard Tim Brown recently state on the Shop Talk Show to pick fonts in your fallback font stack that are close to the web font you're loading. That way it won't be as jarring when the TypeKit font loads.
