2. Let's take a look at the differences between intra-row elements and block-level elements:

1. Intuitive differences between intra-row elements and block-level elements

The elements in a row are arranged in a straight line and arranged horizontally in the same row.

Each block-level element occupies one row and is arranged vertically. Block-level elements start from the new line and end with a broken line.

2. Block-level elements can contain intra-row elements and block-level elements. The row element cannot contain block-level elements.

3. The differences between intra-row elements and block-level element attributes are mainly in the Box Model attributes.

The width setting of the row element is invalid, the height setting is invalid (line-height can be set), the upper and lower of margin is invalid, and the upper and lower of padding are invalid.

3. Conversion of intra-row elements and block-level elements:

Converts block-level elements into a line element: display: inline;

Converts an element in a row into a block-level element: display: block;

Line block element: display: inline-block;
