A block of markup you copy and paste straight into a post, a page or a template. There is no file to upload and no account to keep, and once it is pasted the section belongs to you.

Not in its colours. This one carries its own paper, ink and ember, so it looks the same in every theme and the same as none of them. Take another treatment if you want your palette.

Almost never, and never as a surprise. This section is core WordPress blocks and nothing else. A few sections in the library ask for our companion plugin, which comes with your access, to move; each one says so on its page before you buy, and each stays a legible section with it switched off.

Yes, in the editor's colour panel like any other block. Three values do the work: the paper, the ink on it and the ember on the label. Change the paper and check the ink still reads.

The colours stay exactly where they are, which is the promise. The typeface and the spacing still come from your theme, so the section changes its face and keeps its palette.

Replace this answer with your own terms. It is the row buyers read most carefully, so say the number plainly here rather than sending them off to a licence page to find it.
