Clean Up, Clean Out And Slants On The Side

Also relates to Peregrinations

Unfortunately I had to say goodbye to a few childhood memories today. My home has suffered a bit from damp the last few winters and I got a real shock when I opened my video/games cabinet last night to discover an entire culture had evolved, that even Mr Bellamy would have been proud of! So the day has been spent restoring my living area to a more habitable balance, paying the bus fare for my herd of woodlice to go and live elsewhere, and disposing of some now unrecognisable classic board games - Risk, Stratego and Dungeon Quest to name a few. Still I did rediscover a few old CDs slipped down the side of the cabinet, including Northern Exposure, which is now bringing back a few memories of those heady clubbing days in the hot Leeds sun of 1997.

Back to the engine now, and been toying around with Python and the transaction capabilities of the InnoDB on MySQL server. Oh and after reading this fun article on using CSS borders to create slants, here is a little herald I created last night (just for amusement). Mozilla and Firebird only for this one.

Another Makeover For The RNIB

Also relates to Web Standards and Accessibility

I decided to join the games this evening and have a quick stab at rebuilding the RNIB home page. Admittedly, a lot of the work had already been done by Simon and the others, but I started with a blank slate to see if I would take the same approach. The final draft is a little and rough and ready - done at speed - but renders consistently across the Windows browsers. Once again I haven't been able to test it on other platforms - barely enough room for a single PC in my office! Since the RNIB serves a specific purpose I set specific structural and design goals for the rebuild

1. Readily resizable content (to at least two times) without breaking up the structure of the page.
2. Logical and accessible structure, that could render easily on an alternative browser (eg Braille or Speech in this case).
3. Keep the design as close to the original as possible (since RNIB had already invested the time in releasing a new front end design, and assuming they have done accessibility checks on the choice of colours). Actually I wasn't totally sure what the original design was intended to be as it looked so radically different across IE, Opera and Moz!

Much of the approach I took appears to be similar to the work already done, however a few areas of the build differ

• Using Fahrner Image Replacement technique on the graphical parts of the page served no purpose in a non-visual environment. For example, the RNIB banner in the top left on screen I placed within the style rule for the top level header element - h1 {background: url('../g/rnib.gif') no-repeat top left;}. Then the text equivalent, cloaked from the screen in a span element, would be served for non-visual user agents, instead of the alt tag of the image.
• I placed the banner at the bottom of the XHTML document, and positioned it absolutely. This way it serves as a reminder when a non-visual UA reaches the end of the page. Some would probably argue that by definition, a banner should be placed at the start of the document, but this is just my view of banners!
• This also meant, there were four clear full width horizontal bars from the top of the page, and I started the main content (ie splitting the columns) below these four rows. Thus, by enclosing all three columns within a wrapper container, the background colour could be set to that of the two sides, to avoid the white space problem that would other arise with using position:absolute to place each column.
• Rather than relying on the pipe divider, I put both the horizontal menus into inline lists using a combination class to extend the rules from one list to the other without impinging on the rules for the vertical lists.
• The date seemed to sit in an odd place when the page was read through a text browser, so I pushed it to the bottom as well, and positioned it using negative relative placement.

That's most of it. I am sure there is a lot that could still be improved, IE does a vainishing trick sometimes over the inner floats, and, the CSS could certainly be improved if more advanced selectors could be used without compromising browser compatibility (good ol IE!?) Oh, and I only set a global selector to switch off borders, margins and padding at the outset since I wanted to do this quickly and working from a blank slate seemed the quicker way to go. Actually worked quite well, although it makes for hard work integrating Fahrner's keyword hack to support IE5.x safely. (I say 5 since @import was used to exclude version 4 browsers, which actually get a reasonable, if plain, styleless version). Finally, the filesize (15KB) is not representable since I removed much of the anchor code, and additional accessibility code would probably still need to be added, plus metadata.
