The latest on using border-radius to make rounded corners

The CSS property border-radius is used to make rounded corners. A rule such as

#twitter {
border: solid 1px blue;
border-radius: 10px;  }

Would round the borders of a an element with the id="twitter" by the same amount on all sides.

As with all CSS rules involving the box model, you could choose to round each corner differently. For example,

#twitter {
border: solid 1px blue;
border-top-left-radius: 8px;
border-top-right-radius: 12px;
border-bottom-right-radius: 16px;
border-bottom-left-radius: 20px;  }

In the past, vendor specific prefixes were needed along with the border-radius property. One was needed in the past for webkit (webkit-border-radius) and for mozilla (moz-border-radius).

The good news is that webkit browsers, which includes Safari and Chrome  no longer need the vendor specific prefix. Firefox after version 4 also supports border-radius. IE9 supports border-radius. Opera supports border-radius.

Heres the take-away headline: modern browsers now work with border-radius.

Review: Moodle for Dummies

Moodle For Dummies (For Dummies (Computer/Tech), written by Radana Dvorak is aimed at the institutional user who is required to use Moodle instead of one of the education management systems like Blackboard. It is not meant for the individual user who might want to set up Moodle on his or her own server.

The book consists of screen by screen and menu by menu explanations of Moodle and its capabilities. It covers creating and managing courses, adding modules to courses, administering courses, setting up questions, grading, and more. There are explanations of how to add chat, blogs, and wikis to a course, and of using databases to share material with your students. You can learn how to set up for different languages, set security, and change the appearance of your course. There’s a chapter on getting reports and statistics and viewing your logs.

The last chapter talks about ways to keep your learners involved, but the suggestions are pretty mundane.

There’s nothing very exciting about Moodle for Dummies, but if you need to learn to use Moodle, this book will get you there.

Summary: A utilitarian explanation of absolutely everything you can do with Moodle.

A review by Virginia DeBolt of Moodle for Dummies (rating: 4 stars)

Now curating HTML5 News

html5 news on scoop.it

I read so many HTM5 posts, I decided to use scoop.it to curate a site called HTML5 News.

You can subscribe to HTML5 News by RSS. If you don’t want to subscribe, I’ve put a link to it in the sidebar here on Web Teacher. You can find it there if you want to take an occasional look.

I’m open to new sources of news if I’ve missed any good ones. You can suggest sources on the HTML5 News site.

We need to face the fact that I’m now officially a fan of apps that allow me to organize and curate topics in which I have an interest. I use Flickr to collect photos of women in tech, I use paper.li to collect tweets from women in web education, and now  scoop.it. Are any one of these tools better than the other?  No, they all have a purpose.

Useful links: Microdata and RDFa, protocol relative, Inclusion, validators

Microdata and RDFa Living Together in Harmony from Jeni’s Musings is valuable reading for anyone interested in the semantic web. It’s a long article full of fine-grained suggestions. She concludes,

Regardless, there are lessons that RDFa and microdata could learn from each other, and changes to both languages that would help developers use them on their own, switch between them and mix them in the same document. I expect and welcome debate about the viability and effectiveness of the changes and guidelines that I’ve suggested here.

Public discussion of Jeni’s post is on Google+ as well as her blog.

7 Awesome iPad Apps For Students

First we had the iPod and it caused a cultural revolution – those white ear buds sold it more than anything else. Apple was quick off the mark to follow with the iPhone which again caused waves in the cell phone market because of its capabilities and mass appeal. Finally Apple has made the vision of Arthur C. Clark come to fruition with the advent of the iPad – a personal handheld computer with a touch screen interface. Apple doesn’t just enter into a market – it creates the market in the first place.

And the iPad has found a special place in the hearts of students all over the world. Why? First off the form factor of it means they’re not having to lug around heavy laptops all the time when they need just basic note taking and web browsing functions. And of course there’s the coolness factor that comes with an iPad – if you don’t have one then you definitely want one. It’s really that simple.
But are there any apps that can really and truly benefit students in their studies and in their scholastic and personal lives?

Convert ($2.99)

You’ll never have to remember conversion ratios ever again – this neat little app does all the work for you.
