Video demonstration col element

| 00:04 | video tutorial: col tag |
| 00:04 | col element represent a column inside a colgroup element (= inside a column group) |
| 00:11 | the table has 4 columns which can be rendered through 4 col elements inside colgroup element |
| 00:19 | 4 columns |
| 00:23 | since col element does not display in browser, we applied a border on it to highlight it |
| 00:26 | we will group ⁄add 3 columns inside the first group of columns and 1 column inside the 2nd colgroup element |
| 00:31 | note: span attribute is not present on colgroup element → we can nest col element inside colgroup |
| 00:51 | thus we have 4 columns (4 col) grouped in 2 columns groups: 3 inside the first colgroup and 1 inside the 2nd colgroup |
| 00:59 | highlighting the colgroup elements; there are 2 inside table |
