Roller tips and tricks: image rollover using CSS

Second post in the Roller tips & tricks Series... as a side note, they are already (too) many webpages out there to teach you how to make image rollover's using CSS, and my intention is not to make yet another similar post. But, as I was searching myself for such info, the top pages returned by Google all --sorry, I admit, I did not follow much links after Page 1 but who does anyway?-- describe a technique of using a background image which is imho very cumbersome --you would need to create a distinct CSS class for each distinct image! So I ended up going back to the CSS Specs to learn enough to be able to write this stuff below. Hope it helps!

How do create (non-background) image rollover using CSS?

When you move the mouse over the images in the Download section of the sidebar, the image changes and shows the text "Get it Now". Here is how it works…

Roller tips and tricks : image and Planet

Apache Roller is the blog-roll application that currently powers the blogs.sun.com site. It comes with a large selection of templates that allows anyone, with no particular programming skills, to easily get started with blogging. To further customize your blog though, you will need to switch to manual and learn some HTML, CSS and Velocity, Roller's template programming language.

I get quite often asked about how to program some of the features that you see on this blog. Simple things but they seem to be of enough global interest, so I'm finally blogging about them here. I'm planning an initial series of 3-4 posts on the top questions that I got so far. There will be more posts of tips & tricks as I get more requests. And always feel free to ask right here, in the Comments section.

How to get images to display in an RSS reader, for sure?

If you upload an image into your blog's resource directory and use it as part of a blog post, Roller will by default strip out the hostname out of the URL. E.g. if you type <img src="http://blogs.sun.com/openomics/resource/happy2009.png" />, Roller will save <img src="/openomics/resource/happy2009.png" />. I.e. it will convert an absolute URL to a relative URL --relative to your blog website's root URL-- if the image sits on the same website. And there's apparently nothing you can do about it --I tried at least and I could not find a checkbox anywhere in the blogger's admin interface to prevent this to happen.

This behavior of course causes no problem to your online visitors. They are surfing your blog's website --here blogs.sun.com-- and the relative URL gets resolved fine by the browser. Your subscribers though, that are reading your blog offline, may run into issues…

FeedBurner accounts are moving to Google

As a follow-up to my posts on Web Analytics (cf Part 1 and Part 2), here is a quick update on FeedBurner. As a reminder, FeedBurner enables a blogger to track his off-site traffic, i.e. his subscribers. FeedBurner gives you a feed URL that replaces the blogging site's default RSS feed and on which it performs extra monitoring and analytics --it basically answers the question of how many subscribers a blog has.

Since the acquisition of FeedBurner by Google in 2007,  users were expecting / hoping a closer integration of FeedBurner with Google's family of products targeted at publishers and advertizers --Google Analytics to start with. Nothing happened in 2008 but things have now started to move. Since the Christmas break, the http://feedburner.google.com/  URL is up-n-running and one can start moving his FeedBurner account & feed to a Google account. Which I did earlier this week.

The migration was very smooth. You simply log into http://www.feedburner.com/, follow a few links to get the migration started and you eventually receive an email notification when it completes. It took about 5 to 10 minutes for my 2 feeds --the entries and comments of Openomics. Google offered me to update my feeds using the feeds2.feedburner.com domain --was feeds.feedburner.com-- which I did not do, but it all works fine still --subscriptions are being redirected from the old to the new domain.

So, good job Google! The only noticeable difference, as shown in Figure 1 above, is that the FeedBurner Stats Dashboard --the plot of subscribers & reach over time-- moved from being histogram-based to a solid-line graph --to align with the graphical standards of Google Analytics, I am guessing.
