| 00:04 | video tutorial: hgroup element |
| 00:10 | hgroup element represents the heading of a section, allowing you to group the next headings: h1, h2, h3, h4, h5, h6 |
| 00:17 | Explanations: |
| 00:17 | <h1> Section heading<⁄h1> represents the heading of that section |
| 00:22 | Question: what if we have more than 1 heading (heading + subheadings) that represents the heading of that section ? |
| 00:43 | in order to make the 2 headings (h1, h2) to represent the heading of the section, we need to group them → thus resulting the hgroup element |
| 00:49 | grouping h1 and h2 headings, by nesting them inside hgroup element |
| 01:08 | h1 represents the heading of the first explicit section in page |
| 01:13 | hgroup (h1+h2) represents the heading of the second explicit section in page |
| 01:20 | if you have more subheadings, these can be added inside hgroup (h1+h2+..) if you whish to be part of the hgroup = the heading of the section |
