HTML5 ol element: render an ordered list
| min | video details |
|---|---|
| 00:08 | the ol element allows us to add an ordered list to the page |
| 00:12 | the li element allows us to add items to the list (ordered in this case) |
| 00:15 | in an ol, the items are ordered by default: ascending - first item has the ordinal value = 1 - the second item has the ordinal value = 2 |
| 00:25 | adding an ordered list (ol) to the page |
| 00:32 | adding items to the list through li element |
| 00:44 | an ordered list displays by default numbers in front of each item (li) |
| 00:50 | now we can fill in the list |
| 01:04 | this is an ordered list with 3 items |
| 01:07 | which renders in browser like this |
| 01:12 | note: by changing the position of the items in an ordered list we're changing the meaning of the list |
| 01:21 | player no2 is now on first position; first position = the winner position (→ if he won the competition than this list is valid, otherwise no!) |
