Element in the CSS row and block-level element

Although some elements can use CSS (display: block/inline) to convert intra-row elements and block-level elements, some cannot. For example, labels such as H1, H2, and H3 embedded in DT do not comply with W3C standards.

Although the problem has been solved, I am not very familiar with the line elements (also called inline elements) and block-level elements. The following content is collected from the Internet.

In the standard document stream, that is, if there is no other CSS style control, the block-level element occupies one line, that is, the bandwidth is always the same as the browser width and has nothing to do with the content. The width of the element in the row is only related to the content.

Inline elements are generally basic elements based on the semantic level (semantic. Inline elements can only contain text or other inline elements. Common inline elements are "".

Both block element and inline element are concepts in the HTML specification. The basic difference between block elements and inline elements is that block elements generally start from a new line. After CSS control is added, the attribute differences between block elements and inline elements will not be different. For example, we can add the inline element cite to the display: block attribute so that it also has attributes starting from the new line each time.
