Frameworks
“… a set of tools, libraries,
conventions and best practices
that attempt to abstract routine
tasks into generic modules that
can be reused.”

CSS RESET
Gleiche Ausgangsbedingungen für Alle!
Eric Meyer – CSS Reset Reloaded
http://meyerweb.com/eric/tools/css/reset/
YUI Reset Demo
Browser-Reset
Eric Meyer‘s Reset-CSS
Pro• Abstände werden zurückgesetzt
• Schriftgrößen unberührt
Contra• ol, ul { list-style: none; }
• <strong> ist nicht bold
• <em> ist nicht italics
Barriere per Default• :focus { outline: 0; }
YUI Reset-CSS
Pro• Abstände werden zurückgesetzt
• lässt :focus unberührt
Contra• H1...H6 erhalten font-size: 100%
• ol, ul { list-style: none; }
• Unnötiges Zurücksetzen von
Standardformatierungen für
strong, em, ins, del, sub, sup
Offene Diskussionen
“The problem I've had with these resets is that
I then find myself declaring much more than I
ever needed to just to get browsers back to
rendering things the way I want. As it turns
out, I'm perfectly happy with how a number of
elements render by default. I like lists to have
bullets and strong elements to have bolded
text. ”
Jonathan Snook, No CSS Resethttp://snook.ca/archives/html_and_css/no_css_reset/
Offene Diskussionen
“I don’t want to take style effects for granted.
[…]
It makes me think just that little bit harder
about the semantics of my document. With the
reset in place, I don’t pick strong because
the design calls for boldfacing. Instead, I pick
the right element – whether it’s strong or emor b or h3 or whatever – and then style it as
needed.”

Back to the root …
SASS
“Sass makes CSS fun again. Sass is
CSS, plus nested rules, variables,
mixins, and more, all in a concise,
readable syntax.”
// Sass h1
height: 118pxmargin-top: 1em
.taglinefont-size: 26pxtext-align: right
/* CSS */h1 {
height: 118px;margin-top: 1em;
}
.tagline { font-size: 26px;text-align: right;
}
SASS
Mixins Generiertes CSS
// Sass
=table-scaffoldingth
text-align: centerfont-weight: bold

=left(!dist)float: leftmargin-left = !dist
#data+left(10px)+table-scaffolding
/* CSS */
#data {float: left;margin-left: 10px;
}
#data th {text-align: center;font-weight: bold;
}
#data td, #data th {padding: 2px;
}
HAML
“Haml is a markup language
that’s used to cleanly and simply
describe the HTML …”
• Markup should be beautiful
• Markup should be DRY
• Markup should be well-intended
• HTML structure should be clear
Compass CSS
Ruby // Sass
Meta-Framework mit Portierungen für Blueprint, 960.gs, YUI
Scaffold – Rapid CSS Development Framework
PHP
Zahlreiche CSS3-basierte Bausteine
Layout-Plugin (CSS 3 Multicolumn Module)
