What type of item should I add to canvas if I have to show and hide it frequently?

I'm a newbie who has to add some text to five areas of a canvas that I will need to show and hide frequently. Was curious what type of tag should I use? I was thinking of using the .append method to add a dynamic DIV or is there a different type of tag that I should use in HTML 5. And is it easy to hide and show. Please help..
