Typekit is one of the easier ways to get fonts fancy working on your Web site. Simply open an account, choose a font and paste a few lines of code into your pages. TypeKit takes care of the rest, to ensure that your loading fonts and there is no unwanted flash content (FOUT) or other problems.
However, there is a possible problem with the default way of incorporation of Typekit fonts. If the code of TypeKit ne fails to load, it may slow down the rest of your site. Typekit avoids FOUT pause your loading of the page for a fraction of a second, but if the script of Typekit does never finished loading, this fraction of a second can turn into several seconds. While Typekit has excellent uptime, admittedly, failures to arrive and understand us if you do not want to hang out on your own site on another.
For those concerned according to Typekit, there is a workaround solution - load Typekit scripts asynchronously. Recently put the Typekit blog has posted an in-depth look at various ways to incorporate Typekit fonts in your pages, including an asynchronous method that does slow your page down with Typekit to become temporarily unavailable.
The disadvantage of the asynchronous design pattern that describes the Typekit is that it is a bit of extra code in your pages. Probably a few more bytes in your HTML code will cause a significant speed hit, but it is something to keep in mind.
