Like many information technology professionals, I've had to become somewhat proficient in basic Hyper Text Markup Language (HTML) coding. As a blogger, that basic knowledge often pays off, particularly when one of my iPhone Life blog posts doesn't look right. I have gathered several great tools throughout the years that help me write and test HTML, the fundamental code that tells your web browser how to present content. If you’re looking for an iPad/iPhone app that can teach you the basics of HTML, check out L2Code HTML ($2.99). This intuitive tutorial app teaches you the fundamentals and also handily provides a color-coded text editor to make creating your own pages (or even formatting blog posts) as easy as pie!
