Inline-level Elements and Inline Boxes in CSS

CSS Web Development Front End Technology

Inline-level elements have their CSS display property set to either ‘inline, ‘inline-table’, or ‘inline-block’ and these elements do not force a line break above and below themselves. Inline-level boxes are generated by each inline-level element which is a part of the positioning scheme as well as contains child boxes.

Inline boxes are boxes which have their content follow inline formatting context. Inline boxes are split into a number of inline boxes whilst those inline boxes that are never split are called atomic inline-level boxes.

Anonymous inline boxes are those boxes over which developer has no control. If a block box contains some bare text and other inline-level boxes, then the bare text around inline-level boxes follows inline formatting context and is enclosed in anonymous inline boxes.
