How to spend more time building sites and fewer days debugging IE

Outline The problem we had About CSS Frameworks About Blueprint CSS Our experience

Problem I realised that every new project I began, I was beginning from scratch

Problem Global reset of all browsers to reduce browser inconsistencies . Setup the page layout Setup the typography , images , forms , general HTML tags, etc.

Problem Sometimes, I'd recycle code from previous projects.

Problem … but often I wouldn't .

Problem Reinventing the wheel doesn't always lead to reliable results. http://www.dev102.com/2008/11/25/10-ways-to-programaticly-shoot-yourself-in-the-foot-part-b/

After launch After months of development, the day after you've launched a new site invariably …

The client says… "But we wanted a 3 column layout !"

The client says… "Well, you never told us that …!"

The client says… "We need one, like … right now !"

The client says… "OK, but it'll take a couple of hours to code it up…"

Problem It was not an efficient way to work.

Problem No standards No continuity No flexibility Coding took too long

Problem Debugging took even longer

Search I went looking for a solution…

Solution: Frameworks I'd been looking into JavaScript and PHP frameworks ...

Solution: Frameworks I wonder if there any available for CSS ?

Solution: CSS Frameworks Oh, yes!

What a Framework is “ A set of tools, libraries, conventions and best practices that attempt to abstract routine tasks into generic modules that can be reused .” — Jeff Croft http://www.alistapart.com/articles/frameworksfordesigners

What a CSS Framework is “ A library that is meant to allow for easier , more standards-compliant styling of a webpage using the Cascading Style Sheets language.” — Wikipedia http://en.wikipedia.org/wiki/CSS_framework

What a CSS Framework is “ The goal here is to allow the designer or developer to focus on tasks that are unique to a given project, rather than reinventing the wheel each time around.” — Jeff Croft http://www.alistapart.com/articles/frameworksfordesigners

Problem And we remember how that looked! http://www.dev102.com/2008/11/25/10-ways-to-programaticly-shoot-yourself-in-the-foot-part-b/

Types of CSS Framework Preset-layouts Grid-layouts Content with Style Yahoo! UI Grids 960 Grid System Blueprint CSS YAML

Preset-layouts: Content with Style Vertical navigation Horizontal navigation

Grid-layouts: Blueprint CSS 24 columns

Elements of a CSS Framework Global reset of all browsers to reduce browser inconsistencies . Setup the page layout Setup the typography , images , forms , etc. Modular Optional plugins

Advantages Cross-browse r support Faster development time Well-structured, modular code Visual design cohesion Helps beginners learn

Disadvantages Often non-semantic Bloated code Limited — a lack of flexibility You inherit other people's bugs Can take time to learn

Disadvantage #1: Non-semantic (1/2) Often get non-semantic classes such as: <div class="column span-4"> Either add an ID to <div id="logo" class="column span-4"> And/or copy the code for these non-semantic classes into your CSS code for #logo once you're happy with the design.

Disadvantage #1: Non-semantic (2/2) Custom CSS #logo { background-color: black; float: left; margin-right: 10px; width: 150px; } Declarations from .column and .span-4 in framework.

Disadvantage #2: Bloated code (1/3) CSS Frameworks generally try to cover every eventuality . Unlikely you'll need to use every declaration in every project. Blueprint CSS is only 15 KB compressed including print.css and ie.css . Use Firefox plugin Dust-Me Selectors to identify unused selectors in your CSS files. www.sitepoint.com/dustmeselectors/

Disadvantage #2: Bloated code (2/3) Dust-Me Selectors www.sitepoint.com/dustmeselectors/

Disadvantage #2: Bloated code (3/3) And/or compress the code code.google.com/p/minify/ Minify! YUI! Compressor developer.yahoo.com/yui/ compressor

Disadvantages: Limited CSS Frameworks can be limited to the needs of the author, lacking flexibility. Many frameworks have MIT or GPL licences allowing you to adapt them. Most frameworks are modular , so just write your own plugins to extend them.

Our experience I like!

Our experience Coding standards Continuity across sites Flexible and maintainable Fast , great for 'sketching' ideas

From this:

To this ... in about 1 hour

Our setup: common files framework.css style.css

Our setup: audience external.css internal.css students.css pgstudents.css staff.css

Our setup: layouts external_home.css internal_home.css layout4.css layout5.css layout3.css layout2.css

Example: External layout 2 framework.css style.css layout2.css external.css

Example: Internal Staff layout 2 framework.css style.css layout2.css internal.css staff.css

Example: Internal Students layout 2 framework.css style.css layout2.css internal.css students.css

Our setup: columns within content Each layout has custom classes for columns .column1of2 .column2of2 .column1of3 .column2of3 .column3of3 .column1of4 .column2of4 .column3of4 .column4of4 .column1of1-23 .column2of1-23 .column1of12-3 .column2of12-3 .column1of1-234 .column2of1-234 .column1of123-4 .column2of123-4

Example: multiple columns .column1of1-23 .column2of1-23

Middle of the presentation Time for half-time oranges

Conclusion Get things done much faster Continuity across sites Standard way of doing things Flexible and maintainable
