Web Font Anti-pattern: Data URIs—zachleat.com
After I posted my Critical Web Fonts article on Twitter, I had an interesting conversation with a developer named Wim Leers about embedding Web Fonts as Data URIs. @zachleat @MarcDrummond Why not just embed as a data URI in the critical CSS? Cached, no FOUT. Example: https://t.co/tqQ03G3dhf. — Wim Leers (@wimleers) January 6, 2016 His suggestion was to embed the font directly in a style block on t
Optimizing SVGs in data URIs by Taylor Hunt on CodePen
Awhile back, CSS-Tricks posted “Probably Don't Base64 SVGâ€, which concluded that SVGs in data: URIs are smaller used as-is instead of base64-encoded. It’s got the right idea, but there are a few complications and further optimizations. Better browser support In the provided code, we have: (Assume the ... are replaced with real SVG data) .bg { background: url('data:image/svg+xml;utf8,<svg ...> ...

Noisy URIs
What is this? Data URIs (unique resource identifiers) are resources (such as images) converted into text so that they can be used with webpages without referencing external files. A great explanation of data URIs can be found on CSS-Tricks.com Repeating noise images are very useful for adding a little texture to all kinds on element on a web page. When you're designing in Photoshop it's simple to

The proper MHTML syntax
Reducing the number of HTTP requests is a must, sprites are cool, but a pain to maintain, so there come data URIs (for all browsers) and MHTML (IE6 and 7). I've talked about these things on this blog to a point where the blog comes up in top 10 results in search engines for queries like "mhtml" and "data url". Therefore I think it's my duty to clarify a point for the good of the mankind 🙂 MHTML w
MHTML - when you need data: URIs in IE7 and under
UPDATE: It's very important to have a closing separator in the MHTML document, otherwise there are known issues in IE7 on Vista or Windows 7. The details are here. In the previous post I described what data: URIs are and how they are useful to reduce the number of HTTP requests. Now, the problem with data: URIs is that they are not supported by IE < 8. But, thanks to this article (in Russian), her
