Hey Isabel,
You can paste any HTML code you want to use into the innerhtml section if you make sure you are escaping the single quote or double quote mark that is used to wrap the code. I suggest you view the source code and do it from a source code level so you know what is being used rather than using Dreamweaver.
If you look at the code it says something like thediv.innerHTML = “HTML CODE”
The HTML CODE there is surrounded by two double quotes. So as long as whatever the HTML CODE is doesn’t have another double quote in it you should be fine. Or if you must use a double quote you can use a backslash to escape that character. Most of the time you can replace any double quotes you might have in your code with single quotes.
