Zooming

Closeread enables the reader to zoom in on particular bits of both code and text using a similar syntax to highlighting

To zoom to particular lines of code for your reader, you can add an attribute to your trigger called zoom-to. To zoom to a line of code, you can either use a line number or a span id.

• zoom-to="3": zoom to line 3
• zoom-to="cr-love: zoom to the line containing the span cr-love

The following section demonstrates that functionality.

The limerick is a form of poetry composed of five lines.

Here is the first limerick appearing in the written record, from the Saint John Daily News in 1880.

The end of the first two lines of a Limerick must rhyme.

The end third and fourth line also rhyme and are nudged in a bit.

hlz is a short-cut that you can use when you want to zoom into on a line while also highlighting it (or a span within the line).

Let’s revisit the limerick.

Let’s focus on this line.

Or this phrase.
