In a block-level container, when the total number of inline-level boxes in a row When the width is smaller than the width of the container, the text-align attribute is used to specify the horizontal distribution of these inline boxes in the line.
In fact, the text-align attribute determines how the inline-level boxes are distributed horizontally in the line by specifying which point the line box is aligned with. It can only be applied to block-level elements. Its most typical application is to specify the horizontal alignment of each line of content in a paragraph.
A paragraph is a block-level container. Each line of content in the container will generate a line box. You can think of a paragraph as a stack of these line boxes. Since not every row of content can fill the width of the container, you can use the text-align attribute to specify the horizontal alignment of the content in each row.
