Feedback from that article suggests that, besides some uncertainty about how large a jump break section should be, some people are still uncertain how to add a jump break, in the first place.
Jump break sections, unlike some other "read more" solutions, can be uniquely located and sized in each post. This requires the blog will not use a dynamic view.
You can make any given jump break as large, or as small, as you wish - when you wish.
You simply edit each individual post - and manually insert the jump break, as required. Older blogs may need an update to the post template. Really old blogs - or blogs with custom templates - may need a bit more of a tweak.
Since there are two post editor modes - "Compose" and "HTML" - there are two ways to insert a jump break.
- With Compose mode, you use the "Insert jump break" button, on the toolbar.
- Position the cursor, where you want the jump break located.
- Hit the "Insert jump break" button.
- With HTML mode, you simply insert the special "Jump Break" code, where you want the jump break located.
