Good example for this would be almost any online clothing store. When a new shirt gets put on the site how does one make it go to the first slot and slide the rest over or even onto the next page? Is this possible with HTML without change classes or id's every time I add something new to my website?
Almost any online clothing store would be dynamically controlled, i.e. the articles would be stored in a database and be sequentially numbered. It is then a matter of programming to determine which article comes first.
In this gallery example, I use floated paragraphs as containers. You could do the same thing with Div tags or Definition Lists. As new items are added to the top, everything else moves over.
Forgot to reply! This was so helpful! Thank you so much. New problem...
