One area where I regularly hit a wall is when using JavaScript. Documentation on the various browsers' support of JavaScript and the Document Object Model (the DOM - a way of interacting with the various elements within a document in a logical fashion) is not always well documented. Sometimes the information is there, but it takes a lot of digging, and other times it's just time to try and learn by finding what works.

One thing that is very important is to never assume that what works in FireFox will work in Internet Explorer, or any other browser. I'm slightly ashamed to admit that I made this mistake again only last week and only realised the error when the client commented on the problem (thankfully, it was not a production site, but delivering even a staging site to a client like that is never a good idea).
