“Responsive iframes without wrappers did you say?” blog post:

Responsive iframes without wrappers did you say?

⚠️ This article is outdated: Don’t use jQuery. Also, this JS technique does not work well when server side rendering.

Responsive images are pretty intuitive; apply max-width: 100% and voila. But what to do about those pesky iframes (video embeds!) whose height does not remain in ratio to width when responding down? The most common technique you will come across dates back years and involves wrappers styled to preserve a hard-coded intrinsic aspect ratio (typically 16:9). Most of the popular scripts such as fitvids.js utilize this technique.

This approach sucks for few reasons:

  1. Wrappers may not play nice with your current setup. Perhaps your videos are added, sized and positioned via a CMS WYSIWYG.
  2. Is ~75 lines of jQuery really necessary?

Fun with Sass & font icons

⚠️ This article is outdated: CSS in JS is far superior to Sass, and font icons are no longer a good idea. Use inline SVG React components and in certain situations plain old .svg files in img tags.

Icon fonts have been been best-practice for a while now. They allow us to use tons of fully styleable cross-browser vector icons with one lightweight HTTP request.

Folk typically use font icons via non-semantic presentational markup such as class="icon icon-happy-face" that should be avoided. With a pinch of Sass you can add icons to elements purely via your stylesheet using easy to remember names, without polluting your markup. Yay!



OS X Mavericks RubyGems cleanup issue

Ever tried sudo gem cleanup in OS X Mavericks only to be hit with errors like this?

Attempting to uninstall sqlite3-1.3.7
Unable to uninstall sqlite3-1.3.7:
  Gem::InstallError: sqlite3 is not installed in GEM_HOME, try:
  gem uninstall -i /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/gems/2.0.0 sqlite3

Font icons like a boss with Sass & Font Custom

⚠️ This article is outdated: First I moved on to a custom Gulp workflow, then for a while I used SVG symbols and external references with a polyfill. Now I use inline SVG React components, and occasionally plain old .svg files in img tags.

Here we take “Fun with Sass & font icons” to the next level by automating the tedious stuff, including the actual font generation.

Manage all your project’s font icons in one folder as nicely named SVG files. Add icons to this folder to have your fonts magically rebuilt and your Sass automatically set up for you to start using the icons via their nice names; without touching your markup or dealing with non-semantic class names.

What are the perks?


How to optimize SVG

Editors like Illustrator can save out some really dumb SVG code sometimes. Properly optimized SVG files can be as much as 80% smaller. Bunches of empty groups, pointless attributes and many other inefficiencies decrease readability and reliability.

Every SVG file should be manually optimized in 3 passes using:

  1. Your vector graphic editor.
  2. The SVGO command-line optimization tool.
  3. Your text editor.
