CSS frameworks speed up development, ensure usability, meet all W3C standards, are compatible across most browsers, and a hell of a lot more. Sounds marvelous.
Why doesn’t everybody use them? For the novice developer, frameworks may be a little bit tricky to get their head around? That is where this article comes in, to hopefully give everybody a better understanding of what a framework is and how to use it effectively.
We will focus on how to use the Blueprint Framework, a framework that is a little bit more mainstream and mature than the rest (I am not saying better). We have getting started guides, advanced tutorials, plugins, tools and apps, and some insightful further reading articles.
Hopefully, this article will give everyone a better insight into CSS frameworks and eventually love them.

The Blueprint CSS Framework Files
The framework has a few files you should check out. Every file in the ‘src’ directory contains lots of clarifying comments.
Compressed files (these go in the HTML):
- blueprint/src/reset.css: This file resets CSS values that browsers tend to set for you.
- blueprint/src/grid.css: This file sets up the grid (it’s true). It has a lot of classes you apply to divs to set up any sort of column-based grid.
- blueprint/src/typography.css: This file sets some default typography. It also has a few methods for some really fancy stuff to do with your text.
- blueprint/src/forms.css: Includes some minimal styling of forms.
- blueprint/src/print.css: This file sets some default print rules, so that printed versions of your site looks better than they usually would. It should be included on every page.
- blueprint/src/ie.css: Includes every hack for our beloved IE6 and 7.
- lib/compress.rb: A Ruby script for compressing and customizing your CSS. Set a custom namespace, column count, widths, output paths, multiple projects, and semantic class names. See commenting in compress.rb or run $ruby compress.rb -h for more information.
- lib/validate.rb: Validates the Blueprint core files with the W3C CSS validator.
- blueprint/plugins/: Contains additional functionality in the form of simple plugins for Blueprint. See individual readme files in the directory of each plugin for further instructions.
- tests/: Contains html files which tests most aspects of Blueprint. Open tests/index.html for further instructions.
This is a quick tutorial on how you start using Blueprint from Joshua Clayton.
Blueprint should be put in your site’s CSS directory. After you’ve done that, add these three lines to the <head> of your web pages. Remember to make sure the HREF path is correct:
Now, you are good to go. You are ready to tackle Blueprint.

Advanced Blueprint Tutorials
Customizing Typography Baselines with Blueprint CSS
BluePrint’s typography.css file sets up some very nice typography styles that create a beautiful baseline grid. By default, it sets the font-size to 12px and sets up the line-height and baseline of 18px based on that. While this is fine, I often prefer to have a larger font-size than 12px. So how is that calculated?
This small but valuable tutorial explains the equation for customizing Blueprints typography baselines.
One of the neat features of blueprint is a compressor script that not only renders all the various CSS bits that you want according to the given column numbers and sizes for each project into one neat (and compact) CSS file, but it also lets you define semantic classes and ids. And on top of that, the compressor script will also generate a PNG image that conforms to the column size and padding you've selected.

This tutorial focuses on the process of applying a CSS grid (Bliueprint)and designing a prototype of a home page template. The layout design, in this tut, is based on the popular layout seen on many WordPress Magazine themes.

This tool helps you to calculate an individual grid layout for your Blueprint-based website or web application. Being a static grid framework, you usually start with defining the total width of your grid and then separate your workspace into columns. By default, Blueprint comes with a 950px grid, which is divided into 24 columns. However, often this configuration is not sufficient to create the kind of layout you have in mind.
Construct is a visual layout editor based on Blueprint & jQuery, and exists both as a useful tool for CSS designers and as proof that a visual layout editor is possible to acheive with clean CSS & semantic HTML.
Blueprint's Compress.rb: A Walkthrough
The purpose of refactoring Blueprint’s compress.rb and other scripts was to make it much more extensible and useful for developers working on multiple projects. Developers using Blueprint on one or two single sites don’t care that the full Blueprint distribution is packaged with the site. However, developers working on multiple sites from a single computer are often left with the hassle of keeping all these copies up-to-date, with extra custom files floating around and very much a large mess.
The goal of rewriting the compression script was to allow for extreme customization of the output Blueprint CSS as well as ease of keeping projects up-to-date with the newest Blueprint source without much hassle.
Plumb is a clever a web layout composition tool for Blueprint framework. All you have to do is draw some 'stuff' on the pages stage and it will generate the HTML for you. Brilliant!
Blueprint comes with a background grid image, but it only works as a background, and it is not that useful when you are working with colors and final tweaks. This Adobe AIR app gets around this by showing a floating grid, sized at 18px and with Blueprint-sized columns.
It is semi-transparent, draggable, and resizable. So you start it up and align things as you please. It floats to the front, so you can even edit behind it while it is running.
Boks is an AIR application (so it works on Windows, Mac and Linux) that provides a User Interface for Blueprint CSS's framework. It's been designed for those who think the Grid System is good but never really took the time to give it love.

It consists of guides that comply with Blueprint's grid of 24 columns of 30px, 10px wide gutters, and a horizontal width of 950px. Horizontal guides are provided at 18px or 1.5 em line-height for 12 px base font.
