Copying object properties, the robust way

If, like me, you try to avoid using heavy libraries when not needed, you must have definitely written a helper to copy properties from one object to another at some point. It’s needed so often that it’s just silly to write the same loops over and over again. These days, most of my time is […]

On the blindness of blind reviews

Over the last couple of years, blind reviews have been popularized as the ultimate method for fair talk selection in industry conferences. While I don’t really submit proposals myself, I have served several times on the other side of the process, doing speaker selection in conference committees, and the more data points I collect, the […]

Stretchy: Form element autosizing, the way it should be

As you might be aware, these days a good chunk of my time is spent working on research, at MIT. Although it’s still too early to talk about my research project, I can say that it’s related to the Web and it will be open source, both of which are pretty awesome (getting paid to […]

Spot the unsubscribe (link)!

After getting fed up with too many “promotional” emails and newsletters with incredibly obscure unsubscribe links, I decided to make this tumblr to point out such examples of digital douchebaggery. This annoying dark pattern is so widespread that Google even added a feature to Gmail for making those unsubscribe links obvious! Unsubscribe links are crucial […]

Conical gradients, today!

It’s no secret that I like conical gradients. In as early as 2011, I wrote a draft for conical-gradient() in CSS, that Tab later said helped him when he added them in CSS Image Values Level 4 in 2012. However, almost three years later, no progress has been made in implementing them. Sure, the spec is […]

Idea: Extending native DOM prototypes without collisions

As I pointed out in yesterday’s blog post, one of the reasons why I don’t like using jQuery is its wrapper objects. For jQuery, this was a wise decision: Back in 2006 when it was first developed, IE releases had a pretty icky memory leak bug that could be easily triggered when one added properties to […]

jQuery considered harmful

Heh, I always wanted to do one of those “X considered harmful” posts*. 😀 Before I start, let me say that I think jQuery has helped tremendously to move the Web forward. It gave developers power to do things that were previously unthinkable, and pushed the browser manufacturers to implement these things natively (without jQuery we probably wouldn’t […]

Awesomplete: 2KB autocomplete with zero dependencies

Sorry for the lack of posts for the past 7 (!) months, I’ve been super busy working on my book, which up to a certain point, I couldn’t even imagine finishing, but I’m finally there! I’ve basically tried to cram all the CSS wisdom I’ve accumulated over the years in it 😛 (which is partly why it […]

An easy notation for grayscale colors

These days, there is a lengthy discussion in the CSS WG about how to name a function that produces shades of gray (from white to black) with varying degrees of transparency, and we need your feedback about which name is easier to use. The current proposals are: 1. gray(lightness [, alpha]) In this proposal gray(0%) is […]

Image comparison slider with pure CSS

As a few of you know, I have been spending a good part of this year writing a book for O’Reilly called “CSS Secrets” (preorder here!). I wanted to include a “secret” about the various uses of the resize property, as it’s one of my favorite underdogs, since it rarely gets any love. However, just mentioning the […]
