Zoe Mickley Gillenwater gave a talk at Generate Conference in London where she shared several mistakes she made while learning CSS flexbox and other techniques. These included misunderstanding how flex-basis works, incorrectly using CSS transforms like rotateX, and making assumptions about screen reader support that caused accessibility issues. She emphasized that vulnerability and sharing mistakes openly can help both oneself and others learn. Making mistakes is a natural part of the learning process, and perfection should not be expected or feared.
Here are some of the stuff I learnt while making it, and if you are working on responsive design, you should probably keep this as reference. Note: You are free to download, edit, distribute and use this work in any way you want.
Building responsively allows us to create flexible user interfaces that support the widest possible audience with a single front-end codebase. But in embracing the ever-increasing contexts in which our sites are used, performance and accessibility must remain our highest priorities; we must continually question each code addition, and improve our delivery and application techniques to ensure they’re best serving users’ needs.
This talk will explore the challenges of creating fast and broadly-accessible websites and offer approaches that dramatically improve performance, usability, access, and sustainability.

65. “Designed for humans first and
machines second,
microformats are a set of simple,
open data formats built upon
existing and widely
adopted standards.”

66. “HTML design patterns for common
chunks of content that web builders need
to markup anyway.”
“Oh, and Google understands them, too.”

68. REPLACING ABBR
• <ABBR> element is used by screenreaders to expand abbreviations
like “lbs” or “NCAAP”
• However unintended consequences occurred trying to workaround
browser bugs for other HTML elements
• What happens when a screenreaders text like this:
• “Let’s go to <abbr class="geo"
title="30.300474;-97.747247">Austin, TX</abbr>”

72. DATA-ATTRIBUTE
• You can set data-attribute to any element you want.
• Set meta information that can be utilized by JavaScript or CSS later on.
<img src=“john-smith.jpg”
data-imgtype=“mugshot”
alt=“John Smith’s mugshot”>

77. ARTICLE VS ASIDE VS
SECTION
• Marc Grabsanki says:
• Article is unique content to that document
• Section is a thematic grouping of content, typically with a heading -
pretty generic
• Aside is content that is tangentially related, like a sidebar
div has no meaning whatsoever, so there is nothing semantic about
divs
77
78. ARTICLE VS ASIDE VS
SECTION
• Bruce Lawson says:
• Aside is for something tangentially related to its parent element. Or, if a
sibling to the main content, it can be used to make sidebars of navigation,
recent comments, colophons, author bios etc.
• Article is a discrete piece of content that could be syndicated - a blog
post, a news item, a comment, a widget
• Section can also contain articles. for example, you could have a page with a
<section> full of entertainment articles, and a section of political news etc.
78
79. ARTICLE VS ASIDE VS
SECTION
• Molly Holzschlag, Opera standards evangelist, says:
• <section> clarifies <div>
• <article> 'replaces' <div id="content">
• <aside> 'replaces' <div id="sidebar">
• Chris Mills, Opera browser employee, plays it safe:

80. WHAT ABOUT THE DIVS?
• Marc Grabanski, jQuery and HTML5 guy:
• “div has no meaning whatsoever, so there is nothing semantic about
divs”
• Bruce Lawson, Opera browser employee:
• “Like all semantic questions, it depends on the context. If your only
reason for wanting an element is to group stuff for styling, it's a div.”

100. HTML5 AUDIO
• AUDIO element attributes are SRC, AUTOBUFFER, AUTOPLAY,
LOOP, CONTROLS
• If you don’t have CONTROL, player becomes transparent
100
101. HTML5 AUDIO SUPPORT
FF3.5+ S4+ Ch3+ Op10.5+ IE9+
Ogg
Y Y Y
Vorbis
MP3 Y Y Y
WAV Y Y Y
101
102. SUPPORTING AUDIO
<audio controls autobuffer>
<source src="html5audio.mp3" />
<source src="html5audio.ogg" />
<!-- include Adobe Flash player EMBED and OBJECT code
here -->
</audio>
Use Flash for older versions of IE
102
103. SUPPORTING AUDIO
• If you do insert audio, setting the file to autoplay is not recommended,
as it interferes with the experience for web surfers using screen
readers.
• Don’t use WAV file type.
• Better to ship a compact disc to the user instead.
103
108. HTML5 VIDEO
• WIDTH and HEIGHT should be required, IMO, but movie plays anyway
based on the values in the video file itself.
• Video formats may have their own posterframe. The browser should
use that by default unless overridden by valid POSTER attribute value.
• Text can be included within VIDEO element to allow user to download
video if their browser doesn’t support.
• If you want to give users control, use CONTROL attribute.
108
109. HTML5 VIDEO
• Video can start automatically if using the AUTOPLAY=”1” attribute and
value.
• Spec provides for LOOP, AUTOBUFFER which also take a value of O
or 1.
• Codecs support...
109
110. HTML5 VIDEO
“It would be helpful for interoperability if all browsers could
support the same codecs.
However, there are no known codecs that satisfy all the
current players: we need a codec that is known to not require
per-unit or per-distributor licensing, that is compatible with the
open source development model, that is of sufficient quality as
to be usable, and that is not an additional submarine patent
risk for large companies.
This is an ongoing issue and this section will be updated once
more information is available.”

111. CODECS
• Ogg (or “Vorbis”)
• No need to worry about patents
• H.264
• Created by the MPEG group
• If you have blu-ray disc player, you are using it
• WebM
• A wrapper for the VP8 video and Ogg audio streams
111
112. VIDEO CODEC SUPPORT
FF3.6+ S Ch5+ Op10.6+ IE9+
Ogg Y Y Y
H.264 Y Y* Y
WebM (W4.02+) (Ch6+) Y
112
113. LESSONS LEARNED
• To get most <video> support, you need 2 video files: H.264
and .OGG.
• iOS Devices can handle MP4 (H.264)
• Safari, IE, Flash can deliver MP4 (H.264)
• Firefox, Opera can deliver .OGG
• Then hit them with FLV video, which supports H.264
http://camendesign.com/code/video_for_everybody
113
117. LESSONS LEARNED
• Use VLC or Firefogg to encode common movie files types to OGG
• H.264 encoding? Use Handbrake
• If you are hot to trot for HTML5 Video, like, right now, check out Mark
Pilgrim’s tutorial:

• Good primer:
