May was quite a busy month this year wasn’t it? We had NFJS, JavaOne, Firefox 3 is starting to be adopted much more rapidly… phew. Therefore, this month a have a bit larger list of links than usual (and trimmed it down a bunch). All great resources that may not have gotten all the attention they deserved:

CSS

CSS Qualified Selectors [ShaunInman.com] – There could be a proposal to the CSS Working Group for this, and I think that this would be an incredibly useful addition to CSS.

Tomorrow’s CSS today: 8 Techniques They Don’t Want You To Know [Sitepoint] – This article shows 8 really cool CSS selectors for progressive enhancment. Most of these involve variations of the attribute selector (which is not supported by IE6), but there are some very cool ways to decorate elements, especially links, with these techniques.

How To: Resizeable Background Image [CSS-Tricks] – Chris Coyier compares three ways to apply a resize-able background to an HTML element, the best one being a purely CSS solution that is really neat. A good read.

JavaScript

SocialHistory.js: See Which Sites Your Users Visit [RWW] – You may have seen scripts around this topic popping up lately, but Aza Raskin has pulled into a bit of JavaScript so you can include it on your site and provide a better user experience.

April was a GREAT month for blog readers. I pulled some mostly under-recognized posts and blogs from my del.icio.us bookmarks to share them with you. You can add me to your del.icio.us network if you want to keep up on all my bookmarks in real-time.

Firefox

Restore Firefox 3 Smart Bookmarks – If you really miss having Smart Bookmarks for Firefox 3, here is a simple about:config tweak to fix you right up!

Reviewing my bookmarks this month, I found some really great resources that I had to write about. In case you missed them, here are the best which (for the most part) went under-noticed. Enjoy!

HTML

You think you know HTML, don’t you? | kay lives here – An insightful opinion piece about front-end coding in general. Some good discussion is a bonus.

HTML Reference (beta) – SitePoint’s new HTML reference covering concepts, elements, attributes, compatibility and even microformats! You will want to bookmark this for future reference. A perfect complement for their CSS reference.

CSS

CSS Compatibility and Internet Explorer – It is made even more useful because you can see the selectors etc. that IE8 plans to support. Slightly exciting but also a bit disappointing. Good to know though :)
