Text selection units.

Target exact character positions or a relative portion of text.

Index selection addresses exact positions; percentage selection addresses a share of the text. The first row emphasizes three characters while the second emphasizes half the line. Both strings and their selector units remain editable.

A prompt to start from

Use Strata. Create a restrained Bone comparison with two Denim number rows. In the first text layer, use an index selector from 0 to 3 to lift and darken exactly the first three characters. In the second, use a percentage selector from 0 to 0.5 to affect half of its ten characters. Label the two rows quietly at the left and introduce their selector amounts in sequence. Keep strings and range units explicit in the project.

A few useful details.
