I've just finished wrestling with a new website for the Year 11 Ecosystems topic that is beginning in a weeks time. After about 4 full weekend days of creating resources, uploading, fiddling with annoying layout issues and creating buttons that are at least a similar size to one another I'm finally happy with how it looks.
Along the way I discovered that I don't know how to embed Prezi presentations, so to get around that I tried using Quicktime screen recordings and publishing them through iMovie and Youtube. It worked fairly well (but took a while), and another limitation is that students will need to pause the video if they want to read slower or read again, rather than clicking through a Prezi at their own speed.
If someone knows how to embed a Prezi then I would be very happy to find out!
I also found out that you can put tables within tables to help with the layout, and also how important it is to not turn the tables invisible until you're completely done with moving them around.
To make buttons of a similar size I created a background pattern using colorlovers, took a screenshot that was the size of the button I wanted, and then added text to that screenshot in picmonkey. It's taken me about 5 different websites to realise that if I just take a small (button-sized) original screenshot from colorlovers, then I can just take a screenshot of that full size when I'm finished in picmonkey, rather than guessing at how large I should drag the final screenshot.
Now I'm looking forward to seeing how the Year 11's react to the site and the work!
