How many custom data tags are allowed per element. Could I have more than one data- property per element? Can I do something like this?
<img data-longDescription="This is my really long description that would be longer than this." data-anotherCustomData="Hi Mom" src="mysrc.jpg" alt="my image" />
Thanks in advance.
You can have as many
[data-]attributes as you’d like. What’s important is that they don’t share the same name, and that they’re prefixed withdata-.I recommend reviewing the HTML5 specification.
