HTML5 adding all headings in page
| min | video details |
|---|---|
| 00:04 | video tutorial: adding headings in page |
| 00:12 | saying you have the next headings you want to add into your HTML document |
| 00:17 | this is the main heading, so its rank should be 1 → h1 |
| 00:22 | this heading is right under the main heading, so its rank should be 2 → h2 |
| 00:28 | the next 3 headings can be placed on the same level but under h2, so their rank will be 3 → h3 |
| 00:38 | "day one Sistine Chapel", is a heading under h3 → its rank will be 4 → h4 |
| 00:44 | this heading is under h4 → its rank will be 5 → h5 |
| 00:47 | this heading is under h5 → its rank will be 6 → h6 |
| 00:51 | the rank of each heading has been decided, now we can add them (the headings) in page, using the tags: <h1>, <h2>, <h3>, <h4>, <h5>, <h6> |
| 02:10 | the biggest heading is h1 while the smallest is h6 |
| 02:18 | for example purpose: adding paragraphs e.g. a page with headings and paragraphs |
| 02:43 | you can add explicit sections in order to better structure your content: HTML5 way |
| 02:50 | in order to maintain the same semantic, 'Rome' heading will be nested inside a section |
| 02:57 | 'Colosseum', 'Pantheon', 'Sistine Chapel' will be nested inside a section INSIDE 'Rome's section |
| 02:59 | 'day one Sistine Chapel' heading will be nested inside a section INSIDE Sistine Chapel's section |
| 03:03 | and so on..we will continue to nest headings in sections INSIDE sections until we reach the corresponding rank for that heading |
| 03:10 | Example: nesting h2 (+ other tags) inside section element |
| 03:23 | nesting h3 (+ all other tags) inside section element INSIDE h2's section |
| 03:39 | nesting h4 (+ all other tags) inside section element INSIDE h3's section |
| 03:57 | nesting h5 (+ all other tags) inside section element INSIDE h4's section |
| 04:14 | nesting h6 inside section element INSIDE h5's section |
| 04:27 | the display and the semantic have been maintained |
| 04:40 | in order to avoid confusion: if you do not realize the appropriate heading rank for that nested section, better use h1 inside all nested sections like this: |
| 05:16 | the display and the semantic have been maintained in this case too |
| 05:25 | h1's and sections nested inside other sections in order to target the corresponding rank for our headings |
