This is a test of Yahoo User Interface (YUI) and especially its grid layout features, which is why this page is so gaudy. I wanted to prove how the blocks are actually laid out.
It is going to have two equal width columns of text with a header and a footer. I have put the biggest heading in the header division. And the two columns fill the page between that and the footer. Both the header and footer divisions span the page width, which is the 750px option "#doc", and all four structures are HTML divisions. It seems from the way this page is constructed that the grid system does not know how to balance content between the two sides of the layout, that you have to adjust the text if you want to balance it between the divisions. Since YUI does a CSS reset, I had to add back all of the style to get the headings to appear more distinct.
I have added style to make the blocks as distinct from one another as they can be by setting the background color: lightgreen for the body, aquamarine for the main header, green with yellow lettering for the next level header, pink for the paragraph blocks and lightblue for the footer paragraph block which also has italic font styling. I also added bigger fonts for the headers and a top margin for each as the CSS reset strips this all away.
This shows the gutter used by the designers to make this all work with a reasonable probability. The theory is that if all of the variables with how the "A" group of browsers, the most common as well as the best supporting ones for CSS, are treated in a well chosen group of compromises. after careful UI study, that this will work well in all of them. So, between the OS and the browser this standard will look and perform about the same.
I added some new paragraphs to the right-side division, so that should blance the columns more. This page has a link to the URL of the Javascript library that implements the CSS reset and the gridding.
Finally, I centered the header text and justified the paragraph blocks.
Today the Beatle, John Lenon who was murdered in 1980, would have been seventy. My House Mate is 54, which means that his 56th birthday is on a Tuesday and because the Julian pattern ran through from 1901 to 2099, he was born on a Tuesday. Lets see what the cal(1) command says about that.
I needed a break between this paragraph block and a preformatted block showing the shell command output, which has the body background.
