How Do You Remove Unused CSS From a Site? (via) Chris Coyier takes an exhaustive look at the current set of tools for automatically removing unused CSS, and finds that there’s no magic bullet but you can get OK results if you use them carefully. # 21st November 2019, 4:41 am

Datasette: Ability to customize presentation of specific columns in HTML view. Still a work in progress, but Datasette master now allows you to inject links to one or more additional CSS and JavaScript resources (optionally with SRI hashes) which will be included on every page. Each template also now provides CSS classes on the body element derived from the current database and table names to provide hooks for custom styling. Next up: custom template support. # 30th November 2017, 7:27 am

CSS element() function (via) Vincent De Oliveira explores the CSS element function (2 years ago), which sadly is still only supported by Firefox. It lets you render any HTML element as a CSS background image, enabling folding effects, animated backgrounds, live previews and more. # 13th November 2017, 2:34 pm

What are some ways that brought your proficiency of CSS to another level?

An exercise I found useful when I first learned CSS was to implement CSS versions of the designs of popular sites. This was back when most sites still used tables for layout.

Wrapping block elements in anchor tags? I know this wasn’t valid markup in HTML4 but has this changed or is the only option through JS?

jQSlickWrap. Clever jQuery plugin which allows text to wrap around irregularly shaped images, by processing the image with canvas and rewriting it as a sequence of floated horizontal bars of different widths. It’s a a modern variant of the the ragged float trick first introduced by Eric Meyer. # 23rd November 2009, 7:44 am

How to Make a US County Thematic Map Using Free Tools. This is the trick I’ve been using to generate choropleths at the Guardian for the past year: figure out the preferred colours for a set of data in a Python script and then rewrite an SVG file to colour in the areas. I use ElementTree rather than BeautifulSoup but the technique is exactly the same. The best thing about SVG is that our graphics department can export them directly out of Illustrator, with named layers and paths automatically becoming SVG ID attributes. Bonus tip: sometimes you don’t have to rewrite the SVG XML at all, instead you can generate CSS to colour areas by ID selector and inject it in to the top of the file. # 12th November 2009, 10:49 am

It’s interesting to me how much [Closure] feels like a more advanced version of Dojo in many ways. There’s a familiar package system, the widgets are significantly more mature, and Julie and Ojan’s Editor component rocks. The APIs will feel familiar (if verbose) to Dojo users, the class hierarchies seem natural, and Closure even uses Acme, the Dojo CSS selector engine.

Girlfriend as a case study

I’ve been helping my girlfriend recreate her site using CSS and structural markup. She’s new to web design and has been taking to CSS like a duck to water—as a veteran of Microsoft Word globally defined styles come to her naturally and she took very little time to cotton on to the importance of seperating presentation from content. I’ve shown her tables as well but she isn’t really interested as she sees CSS as a much better solution for general presentation. I’m hoping to help run an HTML/XHTML/CSS training course at the University early next year with a heavy emphasis on structural markup, standards compliance and accessibility so it’s great to have a guinea pig to play with :)
