Microdata in HTML5 and what it means for technology
Fresh off an opportunity to help shape early use of Microdata in Google, let’s talk about some ways Microdata might be used in the future and its overall potential for driving innovation in technology.
The top 5 dumbest things Web developers do today
The Web is certainly much different in 2007 than it was in 1997 when I created my first Web site. There were things back then that were really annoying (under construction .gifs, blinking text, and ugly frames)… I certainly contributed to the ugliness. But 2007 has its share of terrible Web practices too. That got me thinking: what bothers me the most about Web pages today? Here’s my top 5 list of the poorest things Web developers are doing in 2007.
What’s the difference between HTML and XHTML?
If you’ve mastered HTML, you’re 90% of the way towards using XHTML. They’re actually very much the same thing—tag-based markup languages used to display Web pages. The difference is only seen by the people creating the pages (Web designers, programmers, etc.) and focuses on “forgivability”— HTML allows for some ugly code (mixed case tags like <BoDy>, improperly nested elements, and unclosed tags), while XHTML does not. If you write HTML, it’s probably a good idea to start using XHTML practices anyway. It will take 5 minutes to learn, and it’s just a better way of doing things.
What’s the difference between <span> and <div> tags?
<span> and <div> tags both allow a Web designer to style text and add other formatting attributes to their Web page. They are not interchangeable tags, though. <div> tags are block-level elements, whereas <span> tags are not. This article explains this, and other differences, between <span> and <div> tags.
Prevent files from being indexed with robots.txt
It is common to publish Web pages, images, and other files on your Web site that you do not want everyone to see. By using robots.txt, you can make broad declarations about which files are browsed by robots (and potentially found by users) and which files are hidden (unless you tell someone exactly where they are!).
