W3C Working Draft )(
Ex: Pure red would have a W3C lightness of 76 ( 0.299 normalized).
sRGB Luma ( Rec. 709 )
Ex: Pure red would have a lightness of 54.2 ( 0.21 normalized).
Using Weighted Euclidean Distance in 3D RGB Space
This method is not official, but it has been reported that it produces better results than the above two:
Ex: Pure red would have a lightness of 125.1 ( 0.49 normalized).
In order to determine which of …
…years later, the stylesheet was introduced in the HTML4 specification along with the W3C Validator service. The service was designed to help people generate syntactically accurate markup in both HTML and CSS. It worked. In the early 2000s validation symbolized professionalism among web developers. Everyone had the badges on their page. Everyone was drinking the validation kool-aid.
Validation Is No Longer Useful
Over the past five or so years our web development workflows have begun …
How to use the W3C Geolocation and Google Geocoding APIs to reverse-geocode at a browser level
How to speed up responses with caching
How to test virtually every aspect of the app as it's built
Includes the source code of a Rails app with easy to read code and high performing geospatial queries
posted some thoughts today about how he wishes the W3C would architect the next version of the Content Policy.
I agree with Alex that designingas a "library" that uses other browser primitives would increase its long-term utility and make it compose better with other platform features.
Alex is advocating the use of extensible web principles in the design of this , and I wholeheartedly support his approach.
The W3C Navigation Timing specification provides a browser API and visibility into the timing and performance data behind the life of every request in the browser. Let's inspect the components, as each is a critical piece of delivering the optimal user experience:
Given the URL of a resource on the web, the browser starts by checking its local and application caches. If you have previously fetched the resource and the appropriate cache headers were provided ( …
…they've stayed remarkably stable because that's the best way to prevent breakage. Like the W3C says: Cool . Which means this isn't much of a problem in the wild and even if it was, don't change would still have big holes with direct links break.
Good explain what all the possible attributes of a resource are. They explain the possible values of those attributes. The options available and … docs
…magic image format ( mif) . How do we deploy it? As a recent bug on W3C points out , our markup provides no facility to specify different formats for a single image. Let's assume we add such mechanism. The syntax does not matter, I'll just make it up for the sake of an example:
<img srcset= "awesome.jpeg 1x, awesome.mif 2x" alt= "Use awesome MIF for retina screens!" >
So far, so good. The browser reads the page and decides to load the . mif …
to help coordinate cross-technology architecture developments inside and outside W3C
As has said before , the existing web architecture needs reform that would make it more layered. We should be able to explain the declarative parts of the spec (like markup) in terms of lower level primitives that compose well and that developers can use for other purposes.
And the W3C must coordinate much more closely with, the (very active) committee that is designing …
On November 18, 2010, the W3C made the decision to no longer support the standard. This was due to disagreement from a number of vendors - including Mozilla and Microsoft - on how it should be practically implemented and incomplete browser support. As a result, IndexedDB was introduced as an alternative standard for web data storage.
However, IndexedDB is not a browser database but an Object Store . It allows for applications to design, store and manipulate objects, without sterilization, …
