I used the CSS overflow Property today and set it to ‘auto’ so that my code fit on the screen.
pre { overflow: auto; }

CSS :last-child:after
I used the CSS :last-child and :after selectors to hack the content: property on my menu lists. Basically items in the menu have a pipe ‘|’ between them, except no pipe before or after the list. I did that in CSS with:
#menu li:after {
content: ' | ';
}
#menu li:last-child:after {
content: '';
}
How To Set Cron to Run Every 5 Minutes
Thanks to this handy document How To Set Cron to Run Every 5 Minutes I now my crontab configured so that my jj5-test repo gets updated every five minutes. It’s the sort of thing I generally do in a post-commit hook, but in this case that won’t work owing to the way the servers are configured (the files are in my account and not owned by the www-data user the commit-hook runs as).
So to configure cron I issued the command:
$ crontab -e
And then to update my svn working copy:
# m h dom mon dow command */5 * * * * cd /home/jj5/web/test && svn update > /dev/null
Handling character encodings in HTML and CSS
On my list of things to do is read the document Handling character encodings in HTML and CSS from the W3C. For some reason I can’t quite bring myself to concentrate on it right now.
HTML5 and CSS positioning
I stumbled across a weird bug today that I didn’t know about and wasn’t expecting. I’d done a little bit of a CSS file to go with a little bit of HTML that did some simple positioning of content. Then I validated my document on the W3C Markup Validation Service and it complained about a missing doctype. So I added a doctype for HTML5. After I did that my page looked all screwy, the CSS positioning was applying correctly. Anyway it turned out that the reason the CSS wasn’t applying was because I had property specifications like this:
#content {
margin: 170 50 50 50;
padding: 0;
}
Whereas I needed to specify the units, like this:
#content {
margin: 170px 50px 50px 50px;
padding: 0px;
}
PHP heredoc syntax
Today I used the PHP for the first time.
$data = <<<EOF my data EOF; echo $data;
view-source URI scheme
Today I learned about the view-source URI scheme. Check it out!
URI scheme
Reading about URI schemes today.
The UriSchemes page at the W3C suggests a few ways to add support for URL schemes. Maybe I could get file: URLs doing something suitable for SMB network resources in Firefox.
Internet explorer support for file URIs
The URI file://bender-xp/C$/ works in an anchor tag in IE8 to open the \\bender-xp\C$ file share on my network. In this case bender-xp was the name of my local machine but it works for remote file shares too (I tested it to a Samba share on another box).
Unfortunately my version of Firefox (version 9.0.1) doesn’t support this.
