AEAChicago2007 – “Secrets of the CSS Jedi” by Eric Meyer

Back to main AEAChicago2007 post

Web 2.0 reflection of Yoda!
isindex tag? from HTML 1.0, no one's used it in five years or so.
display: table doesn't have to only apply to tables
padding on images not just text; images have backgrounds
punchouts with transparent images so changed background on rollover
	shows through
turn a table into a bar graph
	old version on Meyer's site
	table { display: block; position: relative; }
	tr, th, td { position: absolute; bottom: 0; }
	tr { width: 25% } (create columns)
	th, td {width: 100%; }
	thead tr { left: 100%; top: 50%; margin: -2.5em 0 0 5em; }
	(headers outside table)
	thead th positioned correctly - legend with border on each th
	table #q2 {left: 25%; border-right: 1px dotted #999; } etc
	table tbody th { top: .75em; vertical-align: top; }
		(Q1 label at top of column)
	start using <th scope="row"> and <th scope="col">
	tbody td.sent vs td.paid colors
	position td.sent on left of column, 40% wide
	and td.paid on right, 40% wide
	borders set so look like buttons
	outset CSS property doesn't say what colors should be
	so browsers decide (poorly)
	#q1 .sent { height: 36.9%; }
	#q1 .paid { height: 33%; } etc
	precalculated numbers here; since probably coming out of database,
		just program to produce
	or could use JavaScript
	CSS will probably never let you do math: see section 8(?) of CSS1
		but also see CSS3 proposals
	Microsoft had behavior CSS-like property, but many people hate it
	extra div/list/whatever for tick marks at each $10,000
	could use content::after if willing to lose them in IE
	could use tfooter row maybe?
	#ticks { position: relative; top: -30em; margin-bottom: -30em; }
	#ticks .tick { border-bottom: 1px dotted #999; }
	#ticks .tick p { position: absolute; left: 100%; }
		(put them to the right of the graph)
use same markup for horizontal bar graph instead of vertical
accessible and indexable
reset styles
	:focus { outline: 0; }
	table { border-collapse: separate; border-spacing: 0; }
		(need cellspacing in markup)
	blockquote:before, blockquote:after, q:before, q:after { content: ""; }
	blockquote, q { quotes: "" ""; }
Firefox package / Contents/Mac OS/res/ has Firefox's default .css files
line layout is incredibly complicated, so not getting into
can set all elements to display:block and will show head etc. in (most?)
	modern browsers
html element's background inherits upward to canvas
if html element doesn't have a background and body does, it inherits
	upward to canvas
if display html element, there can be space outside it - that's where the
	Force comes from
