3,383 PointsConfused about use of "ID" multiple times on a single html page on 'How to make a website'
There's #wrapper, #logo, #gallery on the same html page. Is this meant only for learning purposes? I thought "Id" could only be used once, the rest being 'classes'.

20,816 PointsWhat they do is correct. Here, you use more than one id's: wrapper, logo, gallery;
What they mean by "'Id' could only be used once, the rest being 'classes'" is that you can't have two elements with the same id.

You can have as many ids as you want on a page but you can only use a specific id once. For example; id="logo" can only be used once on a page. You could also use id="gallery" on the same page but it can be used only once on that page. On the other hand class="someClass" could be used multiple times on a page.
